conflicting types for ‘pthread_barrierattr_t’

[hnkien]

Hello, I got the issue when using with shared library of lwan: /usr/local/include/lwan/missing.h:50:13: error: conflicting types for ‘pthread_barrierattr_t’ typedef int pthread_barrierattr_t; ^ In file included from /usr/include/pthread.h:26:0, from /usr/local/include/lwan/lwan.h:26, from hello.c:2: /usr/include/bits/pthreadtypes.h:249:3: note: previous declaration of ‘pthread_barrierattr_t’ was here } pthread_barrierattr_t;

You should compile your code with '-DHAS_PTHREADBARRIER'.

[lpereira]

This shouldn't happen. What platform and compiler version are you using, @hnkien? Could you please paste the whole output from CMake the first time it's executed (or delete the CMakeCache.txt file and run it again)?

Ah, I see the problem now. Follow @LampmanYao's advice for the moment. The missing.h header should be considered private and no .h files should include it.

[lpereira]

@hnkien It should be fixed now; it would be great if you could test this and report back. Feel free to reopen the issue.
