The following error turns up during the configure step: checking for mutexes... (cached) no configure: error: Unable to find a mutex implementation The culprit seems to be the following (no-longer necessary?) line from /usr/share/crossdev/linux/linux-gnueabi: db_cv_mutex=${db_cv_mutex=no} db_cv_posixmutexes=${db_cv_posixmutexes=no} db_cv_uimutexes=${db_cv_uimutexes=no} db_cv_mutex=${db_cv_mutex=POSIX/pthreads/library/arm/gcc-assembly}
I just stumbled into the same problem. Is there any fix?
For me it fails for version 4.8.30
Commenting the lines suggested by Arun Raghaven resolved the issue, sys-libs/db compiled without errors
These versions are removed from the tree
