Problem: /usr/bin/ld: cannot find -lmcpp
 

Hey all,
I encountered this problem, it seems ld (GNU linker) is unable to find some library? Because I installed this mcpp package into 'some_directory', is there any trick to make it find the 'some_directory'?
Any environment variable of help?

Thanks in advance...

If you compiled "mcpp" with
'./configure --enable-mcpplib --prefix=[some-other-place]'
you will have the libs in "[some-other-place]/lib" and
*) the command ' export PATH="$PATH:[some-other-place]/lib" '
would usually work for "ice" ( It didn't work for me )

So the safe choice is
'./configure --enable-mcpplib --prefix=/usr/'

*) EDIT : A new library path can be added to /etc/ld.so.conf,
* (but not sure if "ice" will find it, I think there are absolute
* paths in some of the Makefile's, will find some libs in /usr/local
* others in /usr only.)

Thanks a lot, knudfl!
Yes, exactly I'm compiling Ice...
