Configuring with GMP in /usr/local

Configuring with GMP in /usr/local

[Neil Jerram]

I have GMP 3.1 in /usr and GMP 4.1 in /usr/local.  How do I invoke
./configure so that it picks up GMP 4.1?

Thanks,
        Neil

Thanks for the response, but I already have /usr/local/bin first in my
PATH, and it doesn't help.  The problem is somehow getting ./configure
to tell gcc to look in /usr/local/{lib,include} before
/usr/{lib,include}.

LDFLAGS="-L/usr/local/lib" Unfortunately /usr/lib may supersede
this and configure will use it first. My advice is to do what I
did. Remove the development library (.a) from /usr/lib and leave
the shared one there for GMP 3.1 (.so) Then install GMP 4.1 in
/usr/local/lib

Your old applications should still use the old runtime libraries
and be fine.

(Remember to ldconfig if you're on Linux.)

Thank you!  I have a working CVS Guile now.
