With dev-db/mariadb-10.2.11 I see: ``` # mysql_config --libs -L/usr/lib64 -lmariadb -lpthread -lnsl -lz -ldl -lm -lssl -lcrypto ``` dev-db/mariadb-10.2.11 appears to use this library directly (i.e. it does not come indirectly from another library): ``` /var/tmp/portage/dev-db/mariadb-10.2.11/work/mysql/configure.cmake 120: MY_SEARCH_LIBS(gethostbyname_r "nsl_r;nsl" LIBNSL) ``` However, net-libs/libnsl is not in DEPEND for dev-db/mariadb-10.2.11.

Changes reverted as libnsl is not ready in stable wrt dependent bug
Could you make this dependency optional? dev-db/mariadb-10.2.14 succeeds to build without net-libs/libnsl...
After investigation, I have found that MariaDB does *not* link to libnsl and therefore depend on it. It is simply looking for gethostbyname_r in nsl which still remains in glibc-2.26. I will look into this more but the dependency is not needed. With the move to split client-libs, this may be obsolete.
I cannot repeat this with newer versions. Marking as OBSOLETE unless new info appears to show how -lnsl gets into mysql_config/mariadb_config
