After running configure and make depend, make fails with the following message : ./../../../libraries/liblmdb/mdb.c:4853:53: error: 'PTHREAD_MUTEX_ROBUST' undeclared (first use in this function) if (!rc) rc = pthread_mutexattr_setrobust(&mattr, PTHREAD_MUTEX_ROBUST); It appears AIX 7?1 doesn't have robust mutexes (https://www.ibm.com/support/knowledgecenter/en/ssw_aix_71/com.ibm.aix.genpro...). Disabling robust mutexes with CPPFLAGS="-DMDB_USE_ROBUST=0" works fine.
