Did it eventually say “Found Threads: TRUE” though? If so, look for what other errors there are. I get the Failed message with my cmake, but also get the Found Threads: TRUE, and everything works.

I’ve added several packages that the CMake output indicated were missing, and the CMake still fails with the same CMakeError output. The only thing I can see is:

-- Performing Test CMAKE_HAVE_LIBC_PTHREAD

-- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed

Is that the issue? If so, how to fix? Thanks.

No, there must have been another error. Keep looking through the output and error logs.

I think it fails. The end of the output along with the cmake error code is:

-- Configuring incomplete, errors occurred!

See also "/u/jcbecker/ganesha.build/CMakeFiles/CMakeOutput.log".

See also "/u/jcbecker/ganesha.build/CMakeFiles/CMakeError.log".

-bash-4.4# echo $?

Did it actually work? Thanks.

Does it actually fail? I see similar errors and everything works find.

Apparently the cmake magic checking for pthread functions looks for both libpthread and libpthreads. Our respective systems have libpthread which if you look below IS were it finds pthread_create, so all should be good.

Hi. I’m trying to build Ganesha 3.4 (latest stable), and CMake output shows the following:

-- Looking for pthread.h

-- Looking for pthread.h - found

-- Performing Test CMAKE_HAVE_LIBC_PTHREAD

-- Performing Test CMAKE_HAVE_LIBC_PTHREAD - Failed

-- Looking for pthread_create in pthreads

-- Looking for pthread_create in pthreads - not found

-- Looking for pthread_create in pthread

-- Looking for pthread_create in pthread - found

-- Found Threads: TRUE  

However CMake fails with the following in CMakeError.log. Not sure how to proceed. Please advise. Thanks.
