t38modem v2.0.0 compile problem

[etcaz]

I'm trying to compile t38modem on 64-bit CentOS 5.6, using the provided opal and ptlib.  I got the libraries to compile (by exporting OPALDIR and PTLIBDIR), but now when I try to compile t38modem itself (with "make USE_OPAL=1 USE_UNIX98_PTY=1 opt"), I run into this:

make DEBUG= default_target

I haven't yet run a "make install" on opal or ptlib, and I'm wondering if that might be part of the problem.  I've tried pointing LD_LIBRARY_PATH at the ../opal/lib_linux_x86_64 and ../ptlib/lib_linux_x86_64 directories, to no avail.  Any idea what's wrong here?

Looks like PTLIBDIR and OPALDIR are not set to the source directories or perhaps you're not using the right versions.

Before making t38modem (ubuntu 10.04 LTS ymmv), I use the following steps:

1) Install dependancies (flex, bison, libtiff, etc)
2) configure, make and install spanDSP from: wget http://www.soft-switch.org/downloads/spandsp/spandsp-0.0.6pre18.tgz
3) configure, make and install ptlib from :  svn co https://opalvoip.svn.sourceforge.net/svnroot/opalvoip/ptlib/trunk -r 24174 ptlib
4) Install the patch for opal found at: https://sourceforge.net/projects/t38modem/files/t38modem/2.0.0/
5) Configure, make and install opal from :   svn co https://opalvoip.svn.sourceforge.net/svnroot/opalvoip/opal/trunk -r 24174 opal
6) Go into the opal/plugins/fax/fax_spandsp directory, and do a make, make install
7) run ldconfig
8) set the variable: export  PTLIBPLUGINDIR=/usr/local/lib/opal-3.9.0
9) Then I get t38modem 2.0 from: http://sourceforge.net/projects/t38modem/files/t38modem/2.0.0/t38modem-2.0.0.tgz
The evnironment variables should be set to the source directories:
export PTLIBDIR=/usr/src/ptlib/
export OPALDIR=/usr/src/opal/

This includes spanDSP and the patch for SIPPDU.  You may not need these.

Hope this helps
