• C++: posix regex error reporting?

  - by Helltone

  I'm writing a small C++ program that parses some strings. I chose to use C's regex.h because I only need POSIX Extended Syntax and I'm concerned with portability. However, I've just noticed that when regexec fails to match, it returns != 0 and I have no idea of what was wrong :-(. I expected to be able to display at least a small message like: line:col: Syntax error or giig sdoigosdigo* sodfg ^ Syntax error Is there a way to know which character did not match? Should I use boost:regex instead? For reference, my regex is: "^" "[ ;\t\n]*" "(" // (1) identifier "[a-zA-Z_][a-zA-Z0-9_]*" ")" "[ \t]*" "(" // (2) non-marking "\[" "(" // (3) non-marking "[ \t]*" "(" // (4..n-1) argument "[a-zA-Z0-9_]+" ")" "[ \t]*" "," ")*" "[ \t]*" "(" // (n) last argument "[a-zA-Z0-9_]+" ")" "]" ")?" "[ \t\n]*" ";" Which matches for instance blablabla[arg1, arg2];

• Cabal: Odd Error Message + Lack of Documentation

  - by voxcogitatio

  So I recently installed cabal (from the default binary of ArchLinux). I then tried to upgrade cabal as a user: cabal upgrade Cabal --user --prefix=$USER Resolving dependencies... cabal: fromFlag NoFlag. Use fromFlagOrDefault What I've already done: Googled the error message. Turned up the cabal source and little else. Looked at haskell-wiki on cabal-install. Looked through this guide. So basically I'm wondering: What's up with the error message? Could anyone point me in the direction of a cabal tutorial?

• i386-mingw32-g++: error trying to exec 'cc1plus': execvp: No such file or directory

  - by Cathy

  If I compile this QT c++ program in SuSE Linux include using namespace std; int main () { cout << "Hello World!"; return 0; When I type i386-mingw32-g++ helloworld.cpp I get the following error i386-mingw32-g++: error trying to exec 'cc1plus': execvp: No such file or directory Is this because MinGW package which i installed contains only gcc in it.. hence i downloaded gcc-g++-3.4.5.rpm package and just copy pasted i386-mingw32-g++ and cc1plus executable along with C++ include files. Pls reply. Thanking You

• App starts in 1.5 emulator but doesn't in 1.6

  - by DixieFlatline

  My app works on 1.5 emulator and 1.5 device. When i try to start it on 1.6 emulator, it produces strange exceptions (doesn't even start). I don't have any 1.6 device to try this app if it works on a real device. I get some warnings in Eclipse ( warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn't come with an associated EnclosingMethod attribute. This class was probably produced by a broken compiler.) and get cant rid of them (i think they come from some apache jars that i need to make http multipart posts). Is it possible that this jars are cause for my exceptions in 1.6 or is it something else? My logacat: 04-29 16:14:55.874: ERROR/AndroidRuntime(392): Uncaught handler: thread main exiting due to uncaught exception 04-29 16:14:55.894: ERROR/AndroidRuntime(392): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.poslji.gor/com.poslji.gor.FormFiller}: java.lang.NumberFormatException: unable to parse 'null' as integer 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2401) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2417) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.access$2100(ActivityThread.java:116) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1794) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.os.Handler.dispatchMessage(Handler.java:99) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.os.Looper.loop(Looper.java:123) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.main(ActivityThread.java:4203) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at java.lang.reflect.Method.invokeNative(Native Method) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at java.lang.reflect.Method.invoke(Method.java:521) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at dalvik.system.NativeStart.main(Native Method) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): Caused by: java.lang.NumberFormatException: unable to parse 'null' as integer 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at java.lang.Integer.parseInt(Integer.java:358) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at java.lang.Integer.parseInt(Integer.java:333) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at com.poslji.gor.FormFiller.nastavi(FormFiller.java:322) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at com.poslji.gor.FormFiller.onCreate(FormFiller.java:188) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1123) 04-29 16:14:55.894: ERROR/AndroidRuntime(392): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2364)

• "Forked Java VM exited abnormally" error from junit tests

  - by Alb

  I have a java junit test that passes when run alone on a development machine. We also have a hudson job which runs all the tests, invoked via ant, on a Mac OS X 10.4 node with Java 1.5. The test was passing in the hudson build until recently but now (with no related code changes) one test fails everytime with the following error: Error Message Forked Java VM exited abnormally. Please note the time in the report does not reflect the time until the VM exit. Stacktrace junit.framework.AssertionFailedError: Forked Java VM exited abnormally. Please note the time in the report does not reflect the time until the VM exit. googling shows many others seem to have run into the same problem but there I couldn't find any answer.

• openmp in mex : stackoverflow error

  - by Edwin

  i have got the following fraction of code that getting me the stack overflow error #pragma omp parallel shared(Mo1, Mo2, sum_normalized_p_gn, Data, Mean_Out,Covar_Out,Prior_Out, det) private(i) num_threads( number_threads ) { //every thread has a new copy double* normalized_p_gn = (double*)malloc(NMIX*sizeof(double)); #pragma omp critical { int id = omp_get_thread_num(); int threads = omp_get_num_threads(); mexEvalString("drawnow"); } #pragma omp for //some parallel process..... } the variables declared in the shared are created by malloc. and they consumes with large amount of memory there are 2 questions regarding to the above code. 1) why this would generate the stack overflow error( i.e. segmentation fault) before it goes into the parallel for loop? it works fine when it runs in the sequential mode.... 2) am i right to dynamic allocate memory for each thread like "normalized_p_gn" above?

• Zend RegEx Validator error message issue

  - by Mallika Iyer

  Hello, I'm validating a text field in my form as follows: $name = new Zend_Form_Element_Text('name'); $name->setLabel('First Name:') ->setRequired(true) ->addFilter(new Zend_Filter_StringTrim()) ->addValidator('regex',true,array('/^[(a-zA-Z0-9)]+$/')) ->addErrorMessage('Please enter a valid first name'); What I'm trying to accomplish is - how can i display a meaningful error message? Eg: If first name is 'XYZ-', how can i display '- is not allowed in first name.' Is there a way I can access what character the regex is failing for? Would you recommend something else altogether? I thought about writing a custom validator but the regex is pretty simple, so I don't see the point. I couldn't find a decent documentation for the zend 'regex' validator anywhere. If I don't override the default error message, I simple get something like : ';;;hhbhbhb' does not match against pattern '/^[(a-zA-Z0-9)]+$/' - which I obviously don't want to display to the user. I'd appreciate your inputs.

• Mercurial Pull Error

  - by Tyler

  I am new to the dvcs world. My company uses perforce and I'm not a fan so I thought I'd try to use mercurial as a front end. I set it up on a windows machine with TortiseHG, enabled the Perfarce extension, did a small checkout (limiting the target revision) and pulled for the rest. This seemed to be more robust than clone alone. This seems to be working fairly well as I've been able to get up to change 8700 or so. My problem is with an error in the perforce repo. During the hg pull command it hits an error abort: file path/to/file.pl missing in p4 workspace and rolls back the transaction. Is there anyway to bypass or skip that file and force it to continue since this is not a file I care about.

• backgroundDisabledColor error when upgrading from Flex3 to FlashBuilder 4

  - by DShultz

  I've upgraded a FlexBuilder3 project to FlashBuilder4, and I am seeing many compilation errors regarding unsupported tag attributes: The style 'backgroundDisabledColor' is only supported by type 'mx.controls.TextInput' with the theme(s) 'halo' Here is the offending mxml element: <mx:TextInput x="245" y="86" id="code1" maxChars="15" change="enableButton(event)" cornerRadius="9" borderStyle="solid" backgroundDisabledColor="#7977b6" /> ...what is the best workaround for this particular error? I was able to easily resolve a similar error with the "backgroundColor" attribute by changing it to "contentBackgroundColor", and was hoping there was a simple workaround for backgroundDisabledColor as well. I realize I can apply a css style, but I'd rather have a simpler solution as there are many many other attribute errors similar to this one.
