Building check_mysql fails on Solaris

If you are using GCC and your MySQL version was compiled using Sun's C compiler (or the other way round), then it is likely that the configure options will fail, as the configure script will run mysql_config to get the appropriate CFLAGS.

There are various options:

Disable check_mysql by running ./configure --without-mysql.
Allow ./configure to finish, but manually amend plugins/Makefile and remove any non-GCC flags in MYSQLCFLAGS.
Use Sun's C compiler to compile the plugins.
Use a GCC-compiled version of MySQL.
