Tips for debugging SCons code and your scripts

To use local scons source rather than installed:

Put these lines in a shell script and run the script. If you want to run it regularly, make the script executable and put it in your private bin directory. 

   1 SCONS_LIB_DIR=/path_to_scons/src/engine
   2 export SCONS_LIB_DIR
   3 exec python /path_to_scons/src/script/scons.py .

You can also run from a checked-out SCons source dir using bootstrap.py, which takes the same args as SCons. That should always use the SCons engine from where bootstrap.py is found. 

   1 python /path_to_scons_src/bootstrap.py .

If you run the commands by hand, don't include the "exec" in the final line.

To run under debugger:

   1 scons --debug=pdb <args...>
   2 b SCons/Tool/msvc.py:158 # to stop at that file:line, looks for file in sys.path e.g. your SCONS_LIB_DIR
