Add options to Configure in formula Dovecot --with-mysql

(James Brown) #1

I’ve used Brew to install Dovecot but it is not authenticating for me because it was not compiled with MySQL support.

I edited /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/dovecot.rb and added ‘–with-mysql’ to the args section. Then ran ‘brew reinstall dovecot’.

But I still get ‘auth: Fatal: Unknown database driver ‘mysql’’

Anything I’m doing wrong?

Thanks, James.

This seems like a question that’s better of at the dovecot people, as you’re not really using anything of homebrew anymore.

(James Brown) #3

Thanks Sean.

Not sure why you say that. I’m installing using brew (re)install dovecot, so I am using homebrew. I am just trying to slightly modify the config the formula that home-brew uses.

I think what I am doing wrong is not using ‘–build-from-source’?

(Sorry, new to Homebrew).

You’re compiling dovecot and brew isn’t the one throwing an error, dovecot is. In comparison this is a bit like writing apple about a website that you opened on your Mac not delivering the things you ordered.

I’m using dovecot
If you build from source instead of pouring the bottle you will solve your troubles with MySQL

Thanks all. I edited brew’s dovecot config file to include ‘–with-mysql’ and then used:

brew install dovecot --build-from-source

and it now works:

Install prefix . : /usr/local/Cellar/dovecot/
File offsets ... : 64bit
I/O polling .... : kqueue
I/O notifys .... : kqueue
SSL ............ : yes (OpenSSL)
GSSAPI ......... : no

                 : -shadow -bsdauth -sia -ldap -vpopmail
userdbs ........ : static prefetch passwd passwd-file checkpassword sql
                 : -ldap -vpopmail
SQL drivers .... : mysql sqlite
                 : -pgsql -cassandra
Full text search : squat
                 : -lucene -solr

It’s still trying to use pam for authentication, but that’s another discussion!

Thanks again for your help.

Trying on a Mojave-based Mac mini, and this time it is not working. I edited /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/dovecot.rb to finished the ‘args’ section with ‘–with-mysql’. Now when I run:

brew install dovecot --build-from-source

I get:

$ brew install dovecot --build-from-source

I even run:

export LDFLAGS="-L/usr/local/opt/mysql@5.7/lib"
export CPPFLAGS="-I/usr/local/opt/mysql@5.7/include"

beforehand and it still didn’t work.

Any suggestions? Thanks.

Those variables need to be in the formula, otherwise they’ll be filtered out by homebrew.

(James Brown) #9

Thanks Sean. So just add those two lines (without the ‘export’) into /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula/dovecot.rb ?

(Sean Molenaar) #10

You’d have to check other formula. I don’t remember and I’m on my phone right now.

I added:


to the ‘def install’ section, but it fails with:

checking dependency style of clang... (cached) none

I have got it to compile! I commented out the second ‘ENV’ line. So it is just:

Actually that didn’t work. It compiled OK but when I went to connect to Dovecot, it said it didn’t know what mysql was. I then looked at the formula and my edits were not there.

Adding back ‘–with-mysql’ to the args section and ENV[‘LD’]="-L/usr/local/opt/mysql@5.7/lib" after the ‘]’ didn’t work. ‘brew install dovecot --with-mysql’ fails with:

checking for auth_userokay... no
checking for mysql_config... NO
checking for mysql_init in -lmysqlclient... no
configure: error: Can't build with MySQL support: libmysqlclient not found

The libraries are definitely at /usr/local/opt/mysql@5.7/lib.

Actually, they have not been installed there. There are only in Cellar:

locate libmysqlclient /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

Have run ‘brew remove mysql@5.7’ and ‘brew install mysql@5.7’ to no avail.


Have given up on Homebrew for Dovecot and have manually installed it. :frowning:
