Reporting a bug
There is a Bug tracker for ascend outside of this wiki.
Some useful additional information relating to debugging:
Also to be added here:
- about Buildbot (currently inactive/offline)
- using GDB
- correct use of SVN during debugging on the trunk
- using 'pygtk/ascdev' and 'tcltk/asc4dev' from within your working folder
- possible library wrong-loading issues: export LD_LIBRARY_PATH=~/ascend for example,
ASCEND loads its solvers from shared libraries using dlopen. This sometimes causes difficulties with libpthread.so when using gdb for debugging. A solution that sometimes works is along these lines (the exact file location may depend on your Linux distro) is given here. For example:
cd ~/ascend scons -j4 DEBUG=1 test export MYASCEND=`pwd` && export ASCENDSOLVERS=$MYASCEND/solvers/ida:$MYASCEND/solvers/ipopt:$MYASCEND/solvers/lsode:$MYASCEND/solvers/qrslv:$MYASCEND/solvers/lrslv && export ASCENDLIBRARY=$MYASCEND/models && export ^C_LIBRARY_PATH=$MYASCEND LD_PRELOAD="/lib/i386-linux-gnu/libpthread.so.0" gdb --args test/test integrator_idaevent.test1
