I’m using Homebrew to install Dovecot on Mojave, but have to modify the formula to add ‘--with-mysql’.
Unfortunately compiling always fails with: checking for mysql_config... NO checking for mysql_init in -lmysqlclient... no configure: error: Can't build with MySQL support: libmysqlclient not found I added: ENV['LD']="-L/usr/local/opt/mysql@5.7/lib" to the ‘def install’ section of the formula, but it still fails. config.log shows: … KRB5_LIBS='' LD='-L/usr/local/opt/mysql@5.7/lib/' LDAP_LIBS=‘' … And mysqlclient is here: $ locate mysqlclient /usr/local/Cellar/mysql@5.7/5.7.24/lib/libmysqlclient.20.dylib /usr/local/Cellar/mysql@5.7/5.7.24/lib/libmysqlclient.a /usr/local/Cellar/mysql@5.7/5.7.24/lib/libmysqlclient.dylib /usr/local/Cellar/mysql@5.7/5.7.24/lib/pkgconfig/mysqlclient.pc I changed the formula to: ENV['LD']="-L/usr/local/Cellar/mysql@5.7/5.7.24/lib/“ And still get the same thing. Any suggestions? Thanks, James.
