[Pyrex] [Fwd: Re: [Mac Inter Core Duo OS 10.4.9 ] compiler complains about pyrex created .h]

[David Goldsmith]

Sorry, I again forgot to reply to entire list, but: OK, I got it to 
work!  I googled the linker error and found the solution - prefixing the 
linking gcc call with MACOSX_DEPLOYMENT_TARGET=10.4 - but it's unclear 
why this is necessary (i.e., why does the linker, when run manually, 
think the deployment target is 10.1).  Then I had trouble calling the c 
function from my (external) run.py file, until I found the part in the 
LO that says you can't do that directly, you have to use a Python-style 
function defined in the pyx file which calls the external c function as 
an intermediary and then call that Python function from your external 
python file; all very confusing, but at least I got it to work.  (It 
would be nice if the Demos included an example of this manner of usage, 
and if the "Interfacing w/ External C Code" portion of the LO reiterated 
this little strangeness when discussing interfacing w/ external C 
libraries - yes, I know it's said earlier in the LO, but the later 
section is where the issue is ripe.)
