This may be a little off topic for this group, but I wasn't sure where
else to go with the question.  And since see Mr. Decker in here...

I have PythonD, DJGPP and DXE3GEN up and working.  My next step is that
I need to create some Python extensions.  Is there a Hello World type
of example of this in the DJGPP environment?  I've perused the stuff at
the PythonD site and at http://www.python.org/doc/ext but I'm still
left with questions regarding what the requirements are for the DJGPP
environment.

I've set up the following environment vars:
set PATH=c:\djgpp\bin;%PATH%
set DJGPP=c:\djgpp\djgpp.env
SET PYTHONHOME = C:/PythonD
SET PYTHONDIR = C:\PythonD
SET LD_LIBRARY_PATH=/dev/env/DJDIR/lib
SET PYTHONCASEOK=1

Is that what I should really have LD_LIBRARY_PATH set to?  Or am I
supposed to replace the /dev/env/DJDIR with C:\djgpp\lib?

But when I try to build a simple extension I get the following:

C:\EOL_P\test>C:\pythond\bin\python.exe setup.py build

running build
running build_ext
c:/pythond/bin/Modules/Setup

hello_wrap.c -o build/temp.ms-dos-5-i786-2.4/hello_wrap.o
In file included from c:/pythond/include/python2.4/Python.h:55,
                 from hello_wrap.c:1:
c:/pythond/include/python2.4/pyport.h:116:24: error: sys/select.h: No
such file or directory (ENOENT)

hello_wrap.c:5: warning: function declaration isn't a prototype
hello_wrap.c:17: warning: function declaration isn't a prototype
NO PACKET DRIVER FOUND.
error: command 'gcc.exe' failed with exit status 1


Now, I looked for select.h and couldn't find anything with that name.
I'm assuming that either my environment isn't correct, or that I have
to adjust something in the PythonD\lib\python2.4\config\Makefile.
Problem is, I have no idea what that would be!

Apologies for spamming on a noob support issue, but I never found an
example of how to do extensions in the DJGPP environment.

Any tips or pointers to examples or references would be greatly
appreciated.

Thanks a lot,
Brent
