Hi All!,
I am having a little trouble installing bullet on ubuntu 14.04. I am able to get to 99% completion and then I get the error:
[ 99%] Built target App_Bullet3_OpenCL_Demos
Linking CXX executable AppSimpleOpenGL3
…/…/btgui/OpenGLWindow/libOpenGLWindow.so: undefined reference to `pthread_getconcurrency’
collect2: error: ld returned 1 exit status
make[2]: *** [Demos3/SimpleOpenGL3/AppSimpleOpenGL3] Error 1
make[1]: *** [Demos3/SimpleOpenGL3/CMakeFiles/AppSimpleOpenGL3.dir/all] Error 2
make: *** [all] Error 2
I tried to find out what the Error 2 corresponds to for bullet, but with no luck. Here is some additional information provided by the debug option in make:
