[Paraview-developers] [EXTERNAL] Re: Build error

[Biddiscombe, John A.]

can you not just add -lpthread to your exe link flags, and do a make VERBOSE=1 to check that pthread is appended to the end of the list of libs

Hi Alan,

Ok, still no real clues, can you send me your CMakeCache.txt

Thanks,

Chris

Chris,
I am still seeing the same error.

//Thread library used.
CMAKE_THREAD_LIBS:STRING=-lpthread

//Use the pthreads library.

Hi Alan,

It looks like the library is not being linked against pthreads. Can you see if CMAKE_USE_PTHREADS is enabled and what the value of CMAKE_THREAD_LIBS is?

Thanks,

Chris

Hi Alan,

I haven't see this, I will try building with Python 2.6.3 to see if that reproduces the problem.

My latest build error with Linux, non MPI, OpenGL looks like this.  Any ideas?
