Compilation error

[rymdbullen]

I've got some troubles compiling the mosquitto-auth-plugin on a raspberyy pi running RASPBIAN, Version:June 2014, Release date:2014-06-20.

I want to run the backend mysql and I've installed the prerequisites:

mosquitto (1.3.2) mosquitto-clients python-mosquitto (from http://repo.mosquitto.org/debian/mosquitto-repo)
mysql-server-5.5
libmysqlclient-dev
libssl-dev

I've only enabled the mysql backend:

BACKENDS=-DBE_MYSQL

But the compiler complaints:

What do I need to do to have the compiler find these libraries?

Thanks in advance!

Check the LDFLAGS setting in the Makefile, and/or amend it to your
needs. If you want Mysql only, LDFLAGS will have to be set to something
like -lmosquitto -lmysql, depending on your platform. (Find the exact
location of the Mysql libs by running "mysql_config --libs".)

You will not need these:

/usr/bin/ld: cannot find -lpq
/usr/bin/ld: cannot find -lsqlite3
/usr/bin/ld: cannot find -lhiredis
/usr/bin/ld: cannot find -lldap
/usr/bin/ld: cannot find -llber

but you will need -lmosquitto, which is provided as mosquitto-dev or
some such package.

Also, please make sure you're using an up-to-date version of Mosquitto
and its libraries; check mosquitto.org on how to set up your system to
grab from Mosquitto's repository.

Works like charm. Thank you very much for your swift response.

May I add that the solution was to keep only the needed LDFLAGS and install the libmosquitto-dev package.
