Did you try the configure option --libdir=DIR object code
libraries [EPREFIX/lib]
See I am lazy and install my 64bit libraries in /usr/local/lib it my machine
and I am the only user
adrian@iceweasel:/usr/local/lib> file libmysqlpp.so.3.1.0
libmysqlpp.so.3.1.0: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked, not stripped
Personally I hate the split between lib64 and lib - but I understand it.
Part of them problem is that mysqlpp cannot know where you installed
required libraries (my mysql libraries are here /usr/local/mysql/lib/mysql
because I like to build my own version of mysql)
Finally Ray, not really sure what you are asking from mysqlpp? As far as I
know from the Filesystem Hierarchy Standard - the real place mysqlpp should
go is /usr/local/lib.
Its up to you to decide where libraries go and also to provide the path of
your installed libraries to ./configure
