sfml-window interfering with fopen

[joelwilliamson]

I'm using SFML 1.6 on Fedora 17.

#include <stdio.h>
#include <errno.h>
#include <error.h>

int main(int argc, char* argv[])
{
   
    FILE *fp = fopen("./simple_vertex.glsl","r");
    if (errno)
    {
        error(1,errno,"File failed to open");
    }
   
    return 0;
}

compiles and runs fine when compiled with g++ -lsfml-system fopen_error_test.cpp -o fopen_error_test && ./fopen_error_test. If I compile with g++ -lsfml-system -lsfml-window fopen_error_test.cpp -o fopen_error_test && ./fopen_error_test, I get "./fopen_error_test: File failed to open: Resource temporarily unavailable".

Any idea what could be causing this?

Weird. Does it happen only with fopen?

Anyway, make sure that your graphics drivers work fine with OpenGL (try to execute "glxgears").

Its also happening with chmod() and open() in both read-only and write-only modes. My OpenGL drivers are working fine: glxgears runs at 60 FPS. Does SFML run fine with Mesa drivers?

SFML works fine with any OpenGL implementation.

It's really weird, but I don't think it has anything to do with SFML itself. Maybe something weird in your environment.
