------------------------------------------------------------------------
NOTES for Developers
------------------------------------------------------------------------
pygist depends on:
- Python
- Numeric extension to Python
- Yorick's gist package
Layout of pygist directory
---------------------------
gist: Python scripts
src: gistCmodule.c
gist: Yorick gist subdirectory
play: Yorick play subdirectory
Updating pygist's src to new version of Yorick:
-----------------------------------------------
Specifically, the gist and play directories are copied directly
from the Yorick distribution. Diff Makefile.gist with gist/Makefile
to so if Makefile.gist needs changes. Then copy Makefile.gist over
the Makefile in the gist subdirectory.
Building and installing pygist:
-------------------------------
The compilation directions are in README.
It is possible to split the build from the install and make it a
two-step process:
python setup.py build
python setup.py install
The build command creates a subdirectory named "build".
To package for a new pygist distribution:
-----------------------------------------
python setup.py sdist
------------------------------------------------------------------------
Additional notes:
------------------------------------------------------------------------
For unaligned access warnings on DEC Alpha:
------------------------------------------
uac p nofix noprint sigbus
causes code to stop on unaligned accesses.
To compile a debug version of the extension:
--------------------------------------------
python setup.py build -g
python setup.py install
NOTE: On the DEC Alpha, I get a load error with build -g, but if I
follow with an install (no -g), it load ok, and I get something
that I can use with the debugger.
To run totalview on python:
---------------------------
Be in the pygist directory for debugging, so src/gistCmodule.c is in
the directory.
Will need to respond to totalview questions for all shared modules
loaded; answer "no" for all except gistCmodule.so.
To run the test under yorick:
----------------------------
yorick
#include "testg.i"
grtest
quit
Be careful that netscape is not also running on X terminals.
xcmap &
gives the colors available.
