Re: Solaris 10: 64-bit convienience libraries won't build 64-bit shared object

[Edward Maros]

I have tracked down what I believe to be a solution. When I configure my 
application, I use env CFLAGS=-m64 LDFLAGS="-L/ldcg/lib/sparcv9 
-R/ldcg/lib/sparcv9". Inside of my configure.in, I needed to do this:

CC="$CC $CFLAGS"
OLD_CXX="$CXX"
CXX="$CXX $CXXFLAGS"
AM_PROG_LIBTOOL
CC="$OLD_CC"
CXX="$OLD_CXX"

This generates a proper 64-bit libtool. Which raises the question as to 
why the CFLAGS are not being used when generating libtool from the 
configure script.

Thanks,
Ed
