  • Working on a cross platform library...

    - by Alon
    What are the best practices on writing a cross platform library in C++? My development environment is Eclipse CDT on Linux, but my library should have the possibility to compile natively on Windows either (from Visual C++ for example).

  • How to find the real user home directory using python?

    - by nsharish
    I see that if we change the HOME(linux) or USERPROFILE(windows) environmental variable and run a python script, it returns the new value as the user home when I tried, os.environ['HOME'] os.exp Is there any way to find the real user home directory without relying on the environmental variable?. Thanx.

  • Standalone application in C, a good idea?

    - by chutsu
    The term has several definition according to Wikipedia, however what I'm really interested in is creating a program that has all its needed dependencies included within the source folder, so the end user doesn't need to install additional libraries for the app to install. For example, how Mac apps has all its dependencies all within the program itself already... or is there a function that autotools does this? I'm programming in the Linux environment...

  • Subversion with Apache and permissions issues

    - by djechelon
    Hello, I have setup an SVN repository for use with Apache 2 via svnadmin create command and appropriate vhost configuration. I found that, in order to correctly use the repository, this must be owned by wwwrun user (or www group) or chmodded to 777. I would like to ask if it's possible to explicitly tell Apache to impersonate another user when serving requests to a certain path (from vhost.conf), like with suphp extension, so I won't mess with permissions once I create a repository. Thank you in advance

  • Preventing threads from writing to the same file

    - by EpsilonVector
    I'm implementing an FTP-like protocol in Linux kernel 2.4 (homework), and I was under the impression that if a file is open for writing any subsequent attempt to open it by another thread should fail, until I actually tried it and discovered it goes through. How do I prevent this from happening? PS: I'm using open() to open the file.

  • What the best multi-thread application debugger for C++ apps.

    - by Coredumped
    I'm looking for a good multi-thread-aware debugger, capable of showing performance charts of application threads on Linux, don't know if such a thing exists, perhaps as a Eclipse plugin. The idea would be to track per thread memory allocation a CPU usage as well as being able to interrupt a thread and examine its stack trace, local vars, etc. It does not have to be an eclipse plugin or a free tool, do any of you have heard of something similar?

  • find: What's up with basename and dirname?

    - by temp2290
    I'm using find for a task and I noticed that when I do something like this: find `pwd` -name "file.ext" -exec echo $(dirname {}) \; it will give you dots only for each match. When you s/dirname/basename in that command you get the full pathnames. Am I screwing something up here or is this expected behavior? I'm used to basename giving you the name of the file (in this case "file.ext") and dirname giving you the rest of the path.

  • ffmpeg: create a video from images

    - by vailen
    Is it possible to use ffmpeg create a video from a set of sequences, where the number does not start from zero? For example, I have some images [test_100.jpg, test_101.jpg, test_102.jpg, ..., test_200.jpg], and I want to convert them to a video. I tried the following command, but it didn't work (it seems the number should start from zero): ffmpeg -i test_%d.jpg -vcodec mpeg4 test.avi Any advise?

  • Get the number of packages transmitted per connection

    - by Daniel
    How do I get the number of packages transmitted per TCP connection? I am using Java, but i know I will have to fetch the number from the underlying OS, so this quastion applies to Linux and Windows operating systems and will have different answers for each of them, I assume. I need this information to profile the network load of an application which seems to send too many small packages by flushing the socket streams too often.

  • Create ActiveRecord migration then edit in one step?

    - by geosteve
    I find myself doing this a lot: script/generate migration my_new_migration .. then select & copy the generated filename, then paste it into vi to actually write the migration. Is there any way to do this in one step? i.e. when the script/generate migration runs, it creates the file the automatically opens that file in an editor? (I'm working in an SSH terminal window on linux..)

  • C++ Libraries similar to C#?

    - by cam
    I'm coming to C++ from a .Net background. Knowing how to use the Standard C++ Libraries, and all the syntax, I've never ventured further. Now I'm looking learning a bit more, such as what libraries are commonly used? I want to start getting into Threading but have no idea to start. Is there a library (similar to how .net has System.Threading) out there that will make it a bit easier? I'm specifically looking to do Linux based network programming.
