Well, I thought that people capable of building gimp (in win32 this is not
common ;) could build gtk+ as well, but in general (when gimp for win32 is
being built by millions of users wordlwide) this is a hindrance.

However, when it is possible to create downloadable binary distributions
for linux it should not be that difficult to do so for windows as well
(c:\gnu\gtk+ required ;)

But I am slowly beginning to see some of the win32 problems.

It's just a matter of time for msvc to support C, though, so even this
difference will soon vanish (or so).

True, but the commandline switches are not (just on of the problems we
have on irix, for example, as gimp-perl links against perl AND gimp, and
both worlds (perl/libtool) might have different ideas on how to do so).

Hmmm.. what if perl tells me to link against c:\perl\perl.lib but gcc does
not like this on it's commandline?

yes, but msvc isn't and when you pick, e.g. activestate as your perl then
you are pretty much tied to msvc for gimp as well. everything else will
end up in a ral nightmare, as you found out ;)

I also think it was bad for PDL to include the ppport.h header file, as
gimp-perl does the same ;-> What's even worse is the config-trickery I do
in the makefile to increase the chances of libtool and perl coexisting. It
*is* a crual world, even under unix....

No. gimp-perl will detect (not using autoconf this time) wether Gtk is
installed and will not try to do anything graphically if it isn't. This means
thast many scripts will run with default values (somewhat useful) and the
ones depending on Gtk will not be instaled, but scriptability is still 100%.

Extra prizes if the Perl-Server will run (it uses unix domain sockets ;),
but that one is not required either.

Now that's cool! Is that an art form? ;) Whew.

Given that the next version of gimp might make extensive use of modules,
this will be a problem.

Ah, so the tools you switch *to* lack the support to do what you need ;) A
cruel world.

My personal problem with libtool (and to a lesser extent automake) is
that tehy are *very* narrow-minded. They insist on the smallest possible
subset.  For example, I often want to build shared libraries without
-fpic since this works under any platform I care for. It doesn't allow
this. What's even worse, I often just *know* that I can link against that
libperl.a file but libtool refuses because it simply will not link against
.a files.

All that's needed would be a perl ported to mingw32. As I udnerstand it,
mingw is just a gcc that threw away POSIX and gives you a "standard" win32
build environment.

So what is needed is a perl that expects the windows environment and a
unix build environment. On CPAN I cna only find the "standard" (a.k.a.
"perl") and "activestate" ports. I looked at the "standard" README.win32
and it seems to be a truely native port, it works with borland, msvc AND:

         Mingw32 with GCC          version 2.95.2 or better

   The last of these is a high quality freeware compiler.  Support for it
   is still experimental.  (Older versions of GCC are known not to work.)

   This port currently supports MakeMaker (the set of modules that is
   used to build extensions to perl).  Therefore, you should be able to
   build and install most extensions found in the CPAN sites.  See L<Usage
   Hints> below for general hints about this.

I think thsi sounds like the right perl to use. IT can also be configured
for different make flavours.
