  • Undefined symbol sunOglCurPrimTablePtr in Solaris-x86

    - by yowkee
    I was porting a C++ program from Solaris Sparc to Solaris x86. The program utilizes OpenGL library and the compilation is performed in a Sun Ultra27 workstation with the default GCC (3.4.3) and OpenGL library come with the machine. However, the following OpenGL call couldn't found while linking: Undefined symbol first referenced in file sunOglCurPrimTablePtr ../../lib/libgltt.so sunOglCurrentContext ../../lib/libgltt.so which, both sunOglCurPrimTablePtr and sunOglCurrentContext should be available in the default OpenGL library /usr/lib/libGL.so (links to /usr/X11/lib/NVIDIA/libGL.so.1). But I couldn't find anything from it: > nm /usr/lib/libGL.so /usr/lib/libGL.so: Searching on web, SUN or Nvidia didn't lead to any helpful resource. Any clue or helps? Thanks!

  • Apache: How can i see my localhost on 192.168.1.101 from 192.168.1.102?

    - by takpar
    Hi, I'm running Apache on Ubuntu. My IP address is 192.168.1.101 While http://localhost and http://192.168.1.101 work fine in my PC, I cannot access it from within my laptop using http://192.168.1.102 It's strange. I can ping 192.168.1.101 but I got "The connection has timed out." in browser. I'm using default apache config. so this is what my sites-available/default looks like: NameVirtualHost *:80 <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /home/www/public_html <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/www/public_html> Options Indexes FollowSymLinks MultiViews #AllowOverride None AllowOverride all Order allow,deny allow from all </Directory> /etc/apache2/posrts.conf NameVirtualHost *:80 Listen 80 <IfModule mod_ssl.c> # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl # to <VirtualHost *:443> # Server Name Indication for SSL named virtual hosts is currently not # supported by MSIE on Windows XP. Listen 443 </IfModule> <IfModule mod_gnutls.c> Listen 443 </IfModule> my laptop runs Ubuntu as well. so I don't think this is a firewall issue. commands executed in Laptop (192.168.1.102): adp@adp-laptop:~$ ping 192.168.1.101 PING 192.168.1.101 (192.168.1.101) 56(84) bytes of data. 64 bytes from 192.168.1.101: icmp_seq=1 ttl=64 time=32.1 ms 64 bytes from 192.168.1.101: icmp_seq=2 ttl=64 time=54.8 ms 64 bytes from 192.168.1.101: icmp_seq=3 ttl=64 time=77.0 ms 64 bytes from 192.168.1.101: icmp_seq=4 ttl=64 time=100 ms ^C --- 192.168.1.101 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 32.193/66.193/100.717/25.463 ms adp@adp-laptop:~$ telnet 192.168.1.101 80 Trying 192.168.1.101... telnet: Unable to connect to remote host: Connection timed out commands executed in PC (192.168.1.101): adp@adp-desktop:~$ ps afx | grep http 12672 pts/4 S+ 0:00 | \_ grep --color=auto http adp@adp-desktop:~$ ping 192.168.1.102 PING 192.168.1.102 (192.168.1.102) 56(84) bytes of data. 64 bytes from 192.168.1.102: icmp_seq=1 ttl=64 time=32.1 ms 64 bytes from 192.168.1.102: icmp_seq=2 ttl=64 time=54.8 ms 64 bytes from 192.168.1.102: icmp_seq=3 ttl=64 time=77.0 ms 64 bytes from 192.168.1.102: icmp_seq=4 ttl=64 time=100 ms ^C --- 192.168.1.102 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3003ms rtt min/avg/max/mdev = 32.193/66.193/100.717/25.463 ms adp@adp-desktop:~$ telnet 192.168.1.102 80 Trying 192.168.1.102... telnet: Unable to connect to remote host: Connection refused adp@adp-desktop:~$ telnet 192.168.1.102 Trying 192.168.1.102... telnet: Unable to connect to remote host: Connection refused What should i do?

  • Does this mySQL Stored Procedure Work?

    - by Laxmidi
    Hi, I got the following stored procedure from http://dev.mysql.com/doc/refman/5.1/en/functions-that-test-spatial-relationships-between-geometries.html Does this work? CREATE FUNCTION myWithin(p POINT, poly POLYGON) RETURNS INT(1) DETERMINISTIC BEGIN DECLARE n INT DEFAULT 0; DECLARE pX DECIMAL(9,6); DECLARE pY DECIMAL(9,6); DECLARE ls LINESTRING; DECLARE poly1 POINT; DECLARE poly1X DECIMAL(9,6); DECLARE poly1Y DECIMAL(9,6); DECLARE poly2 POINT; DECLARE poly2X DECIMAL(9,6); DECLARE poly2Y DECIMAL(9,6); DECLARE i INT DEFAULT 0; DECLARE result INT(1) DEFAULT 0; SET pX = X(p); SET pY = Y(p); SET ls = ExteriorRing(poly); SET poly2 = EndPoint(ls); SET poly2X = X(poly2); SET poly2Y = Y(poly2); SET n = NumPoints(ls); WHILE i<n DO SET poly1 = PointN(ls, (i+1)); SET poly1X = X(poly1); SET poly1Y = Y(poly1); IF ( ( ( ( poly1X <= pX ) && ( pX < poly2X ) ) || ( ( poly2X <= pX ) && ( pX < poly1X ) ) ) && ( pY > ( poly2Y - poly1Y ) * ( pX - poly1X ) / ( poly2X - poly1X ) + poly1Y ) ) THEN SET result = !result; END IF; SET poly2X = poly1X; SET poly2Y = poly1Y; SET i = i + 1; END WHILE; RETURN result; End; Usage: SET @point = PointFromText('POINT(5 5)') ; SET @polygon = PolyFromText('POLYGON((0 0,10 0,10 10,0 10))') ; SELECT myWithin(@point, @polygon) AS result ; I'm using phpMyAdmin and it blows up when using stored procedures. If this one works, then I'll try to figure out how to call it in php instead. Thanks, Laxmidi

  • User Mode Linux - Installing a module error

    - by Zach
    I am trying to run 'make' on a module in User Mode Linux to install a simple makefile. Here is my make file: obj-m := hello.o KDIR := /lib/modules/$(shell uname -r)/build PWD := $(shell pwd) default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules When I run this in User Mode Linux I get the following error: make[1]: Entering directory /lib/modules/2.6.28/build' make[1]: *** No rule to make targetmodules'. Stop. make[1]: Leaving directory `/lib/modules/2.6.28/build' make: * [default] Error 2 The problem is that no files are present under /lib/modules/. There's no directory for 2.6.28 or build. From what I've read, these should be symlinks to /usr/src, but under /usr/src, I don't see any files under that either.

  • UITableViewCellStyleDefault label width

    - by Rob Bonner
    Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!

  • Expression Encoder SDK - WMA Pro Codec Issues with Windows Server 2003

    - by PortageMonkey
    I am using the Expression Encoder SDK to encode .avi and Flash files to a .wmv format suitable for Silverlight. By default, EE encodes files with audio using the the WMA PRO codec. If you are running Windows Server 2003, this is a problem as it doesn't support the WMA PRO codec and produces and error message similar to the following. Error Message: The Audio Profile settings do not match a valid system profile. Error Source: Microsoft.Expression.Encoder Error Target Site: System.String GetProfileString() I am looking for a way to change the default audio codec to something suitable for WS 2003. I am aware that although not supported natively, there is a highly invasive way to install Windows Media Player 11 and it's codecs on WS 2003 but this involves registry tinkering and other hacks not suitable for our production environments so that solution is out.

  • FormsAuthentication redirecting to login page when visiting root of website

    - by Ryan Lattimer
    I wanted to use FormsAuthentication to secure my static files as well on my site, so I followed the instructions located here http://learn.iis.net/page.aspx/244/how-to-take-advantage-of-the-iis7-integrated-pipeline/ under title "Enabling Forms Authentication for the Entire Application". Now though, when I try to visit the site by going directly to http://www.mysite.com I get redirected to http://www.mysite.com/Login.aspx?ReturnUrl=%2f instead of it using my DefaultDocument I have set. I can go to my default document by just visiting http://www.mysite.com/Home.aspx without any issues because it is set to allow anonymous access. Is there something I need to add into my web.config file to make iis7 allow anonymous access to the root? I tried adding with anonymous access but no such luck. Any help would be much appreciated. Both Home and the Login form allow anonymous. <location path="Home.aspx"> <system.web> <authorization> <allow users="*" /> </authorization> </system.web> </location> <location path="Login.aspx"> <system.web> <authorization> <allow users="*" /> </authorization> </system.web> </location> Login form is set as the loginUrl <authentication mode="Forms"> <forms protection="All" loginUrl="Login.aspx"> </forms> </authentication> Default document is set as Home.aspx <defaultDocument> <files> <add value="Home.aspx" /> </files> </defaultDocument> I have not removed any of the iis7 default documents. However, Home.aspx is first in the priority.

  • Can not set Character Encoding using sun-web.xml

    - by stck777
    I am trying to send special characters like spanish chars from my page to a JSP page as a form parameter. When I try get the parameter which I sent, it shows that as "?" (Question mark). After searching on java.net thread I came to know that I should have following entry in my sun-web.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Sun ONE Application Server 8.0 Servlet 2.4//EN" "http://www.sun.com/software/sunone/appserver/dtds/sun-web-app_2_4-0.dtd"> <sun-web-app> <locale-charset-info default-locale="es"> <locale-charset-map locale="es" charset="UTF-8"/> <parameter-encoding default-charset="UTF-8"/> </locale-charset-info> </sun-web-app> But it did not work with this approach still the character goes as "?".

  • python optparse, how to include additional info in usage output?

    Using python's optparse module I would like to add extra example lines below the regular usage output. My current help_print() output looks like this: usage: check_dell.py [options] options: -h, --help show this help message and exit -s, --storage checks virtual and physical disks -c, --chassis checks specified chassis components I would like it to include usage examples for the less *nix literate users at my work. Something like this: usage: check_dell.py [options] options: -h, --help show this help message and exit -s, --storage checks virtual and physical disks -c, --chassis checks specified chassis components Examples: check_dell -c all check_dell -c fans memory voltage check_dell -s How would I accomplish this? What optparse options allow for such? Current code: import optparse def main(): parser = optparse.OptionParser() parser.add_option('-s', '--storage', action='store_true', default=False, help='checks virtual and physical disks') parser.add_option('-c', '--chassis', action='store_true', default=False, help='checks specified chassis components') (opts, args) = parser.parse_args()

  • WCF Runtime Error while using Constructor

    - by Pranesh Nair
    Hi all, I am new to WCF i am using constructor in my WCF service.svc.cs file....It throws this error when i use the constructor The service type provided could not be loaded as a service because it does not have a default (parameter-less) constructor. To fix the problem, add a default constructor to the type, or pass an instance of the type to the host. When i remove the constructor its working fine....But its compulsory that i have to use constructor... This is my code namespace UserAuthentication { [ServiceBehavior(InstanceContextMode=System.ServiceModel.InstanceContextMode.Single)] public class UserAuthentication : UserRepository,IUserAuthentication { private ISqlMapper _mapper; private IRoleRepository _roleRepository; public UserAuthentication(ISqlMapper mapper): base(mapper) { _mapper = mapper; _roleRepository = new RoleRepository(_mapper); } public string EduvisionLogin(EduvisionUser aUser, int SchoolID) { UserRepository sampleCode= new UserRepository(_mapper); sampleCode.Login(aUser); return "Login Success"; } } } can anyone provide ideas or suggestions or sample code hw to resolve this issue...

  • FxCop giving a warning on private constructor CA1823 and CA1053

    - by Luis Sánchez
    I have a class that looks like the following: Public Class Utilities Public Shared Function blah(userCode As String) As String 'doing some stuff End Function End Class I'm running FxCop 10 on it and it says: "Because type 'Utilities' contains only 'static' ( 'Shared' in Visual Basic) members, add a default private constructor to prevent the compiler from adding a default public constructor." Ok, you're right Mr. FxCop, I'll add a private constructor: Private Utilities() Now I'm having: "It appears that field 'Utilities.Utilities' is never used or is only ever assigned to. Use this field or remove it." Any ideas of what should I do to get rid of both warnings?

  • Mono and Apache are serving files with no ASP.NET processing

    - by dnord
    On a new Rackspace Cloud Server box (Ubuntu 9.10), I've installed apache2, libapache2-mod-mono, and mod-mono-server2. I've disabled mod_mono and enabled mod_mono_auto, but whatever I do, requests for Default.aspx return the actual contents of Default.aspx (in this case, "This is a marker file generated by the precompilation tool, and should not be deleted!") I've installed XSP, and it looks like it works okay, but I'd like to use Apache with mod_mono (seems a more common configuration) if I can get it running. However, this is no error messages and no hints, with Google obviously not terribly helpful. What else can I look for to make sure I'm configured correctly? How can I test further?

  • How can I re-size and re-position a shadowbox/greybox window to display in a certain div element?

    - by kielie
    Hi guys, I would like to know if it is possible to re-size and re-position a greybox or shadowbox window to display in a certain div element? I am creating a template for a wordpress site, and I am using the default calendar, but when you click on a date inside of the calendar, the default action is to open it up in a new window. Would it be possible to mod greybox or shadowbox in such a way that when you click on a date, the box opens up over the calendar displaying the contents in it, instead of a new page? Or is there another way of achieving the desired result, maybe with jQuery or Javascript? Any help would be greatly appreciated, thanx in advance!

  • Python - Number of Significant Digits in results of division

    - by russ
    Newbie here. I have the following code: myADC = 128 maxVoltage = 5.0 maxADC = 255.0 VoltsPerADC = maxVoltage/maxADC myVolts = myADC * VoltsPerADC print "myADC = {0: >3}".format(myADC) print "VoltsPerADC = {0: >7}".format(VoltsPerADC) print VoltsPerADC print "myVolts = {0: >7}".format(myVolts) print myVolts This outputs the following: myADC = 128 VoltsPerADC = 0.0196078 0.0196078431373 myVolts = 2.5098 2.50980392157 I have been searching for an explanation of how the number of significant digits is determined by default, but have had trouble locating an explanation that makes sense to me. This link link text suggests that by default the "print" statement prints numbers to 10 significant figures, but that does not seem to be the case in my results. How are the number of significant digits/precision determined? Can someone shed some light on this for me. Thanks in advance for your time and patience.

  • Read SharedPreferences when you haven't set the name of the file.

    - by Pentium10
    When you createa a PreferenceScreen on Android, your application creates a default SharedPreferences file for the settings. I want to read this name, or get a reference without specifing the name. Currently I use: SharedPreferences prefs = ctx.getSharedPreferences("prefs", 0); SharedPreferences.Editor ed=prefs.edit(); But this returns another copy of the preference. When I checked the folder in /data/data/myapk/shared_prefs I see two files, one named prefs.xml and the other is my [package name]_preferences.xml (this was created by the PreferenceActivity); How do I get an instance of the shared preference with the usage of the default file name, so I should not mention a name for it?

  • Why does SFINAE not apply to this?

    - by Simon Buchan
    I'm writing some simple point code while trying out Visual Studio 10 (Beta 2), and I've hit this code where I would expect SFINAE to kick in, but it seems not to: template<typename T> struct point { T x, y; point(T x, T y) : x(x), y(y) {} }; template<typename T, typename U> struct op_div { typedef decltype(T() / U()) type; }; template<typename T, typename U> point<typename op_div<T, U>::type> operator/(point<T> const& l, point<U> const& r) { return point<typename op_div<T, U>::type>(l.x / r.x, l.y / r.y); } template<typename T, typename U> point<typename op_div<T, U>::type> operator/(point<T> const& l, U const& r) { return point<typename op_div<T, U>::type>(l.x / r, l.y / r); } int main() { point<int>(0, 1) / point<float>(2, 3); } This gives error C2512: 'point<T>::point' : no appropriate default constructor available Given that it is a beta, I did a quick sanity check with the online comeau compiler, and it agrees with an identical error, so it seems this behavior is correct, but I can't see why. In this case some workarounds are to simply inline the decltype(T() / U()), to give the point class a default constructor, or to use decltype on the full result expression, but I got this error while trying to simplify an error I was getting with a version of op_div that did not require a default constructor*, so I would rather fix my understanding of C++ rather than to just do what works. Thanks! *: the original: template<typename T, typename U> struct op_div { static T t(); static U u(); typedef decltype(t() / u()) type; }; Which gives error C2784: 'point<op_div<T,U>::type> operator /(const point<T> &,const U &)' : could not deduce template argument for 'const point<T> &' from 'int', and also for the point<T> / point<U> overload.

  • CakePHP Bake association problem

    - by Apu
    I have only two tables in my database with a one-to-many relationship between them (user hasMany messages) and am trying to get basic CRUD functionality going. Bake detects the associations correctly and specifies them correctly inside the model classes, but in controllers and views it looks like Cake doesn't know anything about those associations -- I don't even get a select tag for user_id when I go add a new message. Has anyone come across this problem before? What can I be doing wrong? Table structure appears to be fine: CREATE TABLE users ( id int(11) NOT NULL AUTO_INCREMENT, username varchar(255) NOT NULL, `password` varchar(255) NOT NULL, email varchar(255) NOT NULL, created datetime NOT NULL, modified datetime NOT NULL, PRIMARY KEY (id) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; CREATE TABLE IF NOT EXISTS `messages` ( `id` int(11) NOT NULL AUTO_INCREMENT, `user_id` int(11) NOT NULL, `content` varchar(255) NOT NULL, `created` datetime NOT NULL, `modified` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

  • Ambiguous Generic restriction T:class vs T:struct

    - by Maslow
    This code generates a compiler error that the member is already defined with the same parameter types. private T GetProperty<T>(Func<Settings, T> GetFunc) where T:class { try { return GetFunc(Properties.Settings.Default); } catch (Exception exception) { SettingReadException(this,exception); return null; } } private TNullable? GetProperty<TNullable>(Func<Settings, TNullable> GetFunc) where TNullable : struct { try { return GetFunc(Properties.Settings.Default); } catch (Exception ex) { SettingReadException(this, ex); return new Nullable<TNullable>(); } } Is there a clean work around?
