```

Compilation of the above code along with #include “tinycthread.h” is successfully done. But while running .exe why am I facing the issue on UBUNTU 14.04…?

Even the same issue when I executed the .exe which is already present in GLFW 3.0.4.

Please help…!!!

The same code when executed on ubuntu 12.04, runs successfully.

Thanks in advance, any help would be appreciated.
