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.
