Please follow the post-install instructions to rebuild all libmysqlclient consumers in the latest versions.
Re-opening because I didn't receive the post_install message. The solution was to rebuild dev-ruby/mysql2 which I expected to be picked up by revdep-rebuild. There is an "virtual/libmysqlclient:=" instruction in the slot 0.3 (and it doesn't work with virtual packages): https://github.com/gentoo/gentoo/blob/master/dev-ruby/mysql2/mysql2-0.3.21.ebuild#L25 Hower, it is missing in the latest ebuild: https://github.com/gentoo/gentoo/blob/master/dev-ruby/mysql2/mysql2-0.5.2-r1.ebuild#L25 Shouldn't it be "MDEPEND="mysql? ( dev-db/mysql-connector-c:= ) mariadb? ( dev-db/mariadb-connector-c:= )" (with :=) ?
(In reply to Anton Bolshakov from comment #2) > Shouldn't it be "MDEPEND="mysql? ( dev-db/mysql-connector-c:= ) mariadb? ( > dev-db/mariadb-connector-c:= )" (with :=) ? No, because these are API-compatible and don't require recompilation after updating the library.
Have you seen an error which(In reply to Hans de Graaff from comment #3) > No, because these are API-compatible and don't require recompilation after > updating the library. Have you seen the error which I was facing? They are compatible between each other but mysql2 complained after major mysql client version upgrade
