My story: I played with a little embedded python
piece of code (python interpreter embedded in wxWidgets app),
and used SWIG to extend this embedded py interpreter.
I did it in Linux, after some ironing all builds and runs as expected.
On a particularily lazy day, I pasted these same wrapper sources to
Win32 (cygnus). After fiddling with the Makefile to point in the right
directions, compilation seems to go ok (give or take a couple of
warnings). But then the linking step chokes with unfriendly messages
like "undefined reference to _PyExit, _Py_Initialize, etc.".
Could someone tell me what this mean? My guess is that my linker is not
pointed at the right Python library, but could someone confirm/rebute
this? I'm pointing the linker (on win32) to -L"/Python23/libs" where
lives "python23.l ib", as presumably I need an equivalent to Linux's
"/usr/local/lib/python2.3/config/libpython2.3.a" , so I'm wondering if
I'm pointing at the right place on the win32 side, or even if I'd need
to compile Python on win32 (currently using some precompiled distro on
win32, while I recompiled Py on Linux). In other words, I'd like to do
all my development on Linux, and not have to redo the work on win32
(besides some cut&paste). If I sound like a win32 newbie, well, I also
like like one:)
Cheers,
Vio
PS I just read on the list some comments that wxWidgets+Pytho n mix is
kinda slow. Bummer. 1 1591

why someone would embedd a python interpreter but write the gui code some
some other language escapes me, but well ;-)

Could someone tell me what this mean? My guess is that my linker is not pointed at the right Python library,
right. you need to create an import lib for gcc. thats done with pexports
and dlltool: http://docs.python.org/inst/tweak-fl...00000000000000
also remember to use -mno-cygwin for gcc if you want to make native win32
apps with cygwin.

is it too slow for _you_?
there are always people that say something is slow, even if it isn't
relevant in real world applications...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
