Re: Barnyard, /usr/bin/ld: cannot find ???lmysqlclient

["Gregory W. MacPherson" <greg () netpublishing com>]

This error - like many compile time errors - is misleading - the
linker found the library, it just doesn't like it:

> /usr/bin/ld: skipping incompatible /usr/lib/mysql/libmysqlclient.so when
> searching for -lmysqlclient
> /usr/bin/ld: skipping incompatible /usr/lib/mysql/libmysqlclient.a when

This says that your system looked in the LIBPATH and in the directory 
where your mysql libraries (presumably) live (/usr/lib/mysql):

> -L/usr/lib/mysql 

and every mysqlclient library instance that it found is not compatible 
with what the build wants. The linker is looking for a reference, and
you probably need a newer version containing an unresolved reference that
your existing libraries do not contain.

Likely, your mysql is backlevel and needs to be upgraded before barnyard 
will compile and link cleanly.

You could just build without mysql, upgrade mysql, and then rebuild 
barnyard with mysql support, but that's more work.
