If that file not exists, DBD:mysqlEmb driver will still not be built, acting like USE="embedded" not selected. I'm using dev-db/mariadb-10.0.27 , libmysqld.a will be built only if USE="embedded" and USE="static-libs" are both set. By briefly watching ebuild dependencies, I found dev-perl/DBD-mysql-4.32.0-r2 has both DEPEND and RDEPEND of "embedded? virtual/mysql[embedded])", virtual/mysql-5.6-r6 has RDEPEND="embedded? (=dev-db/mariadb-10.0*[embedded])". That's not enough. Also, virtual/mysql controls specific DB software USE=static only. USE=static-libs is passed to virtual/libmysqlclient and then controls USE=static-libs of specific DB software. But in fact, virtual/libmysqlclient[static-libs] made not only libmysqlclient.a but also libmysqld.a . It seems oddly. Not tested: 1. I'm using mariadb, I don't know if any other mysql implementation has the same behavior (libmysqld.a requires USE=static-libs). 2. >dev-perl/DBD-mysql-4.32.0-r2 Possible solutions: 1. Give dev-perl/DBD-mysql a DEPEND(not RDEPEND due to statically linking) of "embedded? (virtual/mysql[static-libs])" or 2. (Recommended) Give virtual/mysql a DEPEND line like "embedded? (=dev-db/mariadb-10.0*[static-libs])". This seems to be semantically correct since libmysqld.a controlled by virtual/libmysqlclient is really odd. And We can control this only applied to mariadb if other DB implementation behavior unknown (Minimum changes). Reproducible: Always
Forgot to say, solution 2 may influence all packages depends virtual/mysql[embedded] not only DBD-mysql, therefore not prefect, either. :'(
This is likely going to be resolved by removing embedded support.
