[Coin-symphony] LDFLAGS for 32bit librarary

[claude philippe medard]

Hello,

I just suscribed to SYMPHONY. can't wait to play :-)
I am trying to build a 32bit library on a 64bit linux laptop.
Problem: in SYMPHONY's Makefile,
I can not get my additions to LDFLAGS or SYSLIBPATHS for LINUX to kick in:
-L/usr/lib/gcc-lib/i386-redhat-linux/3.2.3.
I did manage to set the CFLAGS (via MORECFLAGS: -m32 -march=i386
-mcpu=i386.)
to build 32bit objects successfully. However, the loading still tries to
spit spit out
a 64bit lib:
i) warnings while building object files.
ii) when puttting it all together (libsym.so),
   /usr/bin/ld is trying to link in /usr/lib64/objects (reading stuff).

Background:
I am building a 32bit application on my 64bit laptop,
basically because my existing cplex & xpress libs are 32bit libs.
no problem it runs, thanks to g++32/gcc32 CFLAGS or CXXFLAGS
set to:  -m32 -march=i386 -mcpu=i386.

FYI:
I sucessfully built all of my recently downloaded
COIN-Clp/Osi/... as 32bit libs, also adding the LDFLAGS
-L/usr/lib/gcc-lib/i386-redhat-linux/3.2.3.
For example, to hook in cplex 32 bit lib into Osi, i did:
//pwd: coin-Osi:
./configure CXX=g++32 CXXFLAGS='-m32 -march=i386 -mcpu=i386' CC=gcc32
CFLAGS='-m32 -march=i386 -mcpu=i386'
LDFLAGS=-L/usr/lib/gcc-lib/i386-redhat-linux/3.2.3 FFLAGS='-m32 -march=i386
-mcpu=i386' --prefix=/home/claude/funwork/COIN/coin-Osi/i386_linux
--with-cplex-lib="/optimization/ilog/cplex75/lib/i86_linux2_glibc2.2_gcc3.0/static_pic_mt
-lcplex" --with-cplex-incdir=/optimization/ilog/cplex75/include/ilcplex
--disable-cplex-libcheck --enable-static -C

yours,
-Claude Medard
