Swig errors with pbs_python 4.4.0 and Torque 4.2.9

[cganote@…]

Hi,

I've seen a few tickets already on errors with undefined symbols, and I've tried replacing the pbs.py and pbs_wrap.c files as well as the setup.py.in file while compiling, to no avail. I'm still having issues linking these libraries. I'm running CentOS 6.6 and compiling with gcc 4.4.7. Here's what I see:

# Set up a Torque Client
cd torque-4.2.9
./configure --prefix=$(pwd) --mandir=$(pwd)/man  --libdir=$(pwd)/lib64 CC="gcc -m64" --enable-drmaa 
make
make install_clients
export LD_LIBRARY_PATH=$(pwd)/lib64:$LD_LIBRARY_PATH
cd bin
export PATH=$(pwd):$PATH

# Set up pbs_python
cd ..
mkdir pbs_py_again
cd pbs_py_again/
wget ftp://ftp.surfsara.nl/pub/outgoing/pbs_python.tar.gz
tar -xzvf pbs_python.tar.gz 
cd pbs_python-4.4.0/
./configure --prefix=$(pwd) --with-pbsdir=/full/path/to/new/torque-4.2.9
make
emacs Makefile # Because the paths are all screwed up - is this ever going to be fixed?
make install
cd lib/python2.7/site-packages/pbs
export PYTHONPATH=$(pwd)
cd ~
python submit.py #Import pbs

I can not test the torque 5 version. Can you test the:

• https://oss.trac.surfsara.nl/pbs_python/svn/devel
• cd 5.X
• vi cpit, where are torque header files located
• ./makeit
• python
• import pbs

If that works tar the directory and attached this to the ticket.

I cna only test 2.5.X and torque 5.X

Here's what I tried:

wget -r -nd --no-parent https://oss.trac.surfsara.nl/pbs_python/svn/devel/5.X/
vi cpit

First of all i test with swig version:

• SWIG Version 2.0.7

This can make a huge difference. You can comment the 2 include log.h statements in:

• pbs.i

This will disable the pbs log functions and see if this solves your problem.

I assume everything works as expected
