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.
