Re: [Opalvoip-user] ptlib static library problems

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

The following script is OK for me to build t38modem statically against
opal/ptlib only (not against system libs):

----------------------
#!/bin/bash

export PTLIBDIR=`pwd`/ptlib-2.6.3
export OPALDIR=`pwd`/opal-3.6.3
cd $PTLIBDIR
./configure --disable-shared
make optnoshared
cd ..

cd $OPALDIR
./configure --disable-shared
make opt
ln -s libopal_s.a lib_linux_x86/libopal.a
cd ..

cd t38modem-1.1.0

#
# Linker option -static allow to build t38modem statically against
# system libs too. It was OK with OpenH323 on RH73 but currently it
# is fail (Segmentation fault) with OPAL on RHE4 :(
#
#grep "LDFLAGS+=-static" Makefile || echo "LDFLAGS+=-static" >> Makefile

make USE_OPAL=1 USE_UNIX98_PTY=1 USE_LEGACY_PTY=1 optnoshared
----------------------
