Pthread CMake error
by Becker, Jeffrey C. (ARC-TN)[InuTeq, LLC]
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.
