Hi guys,

> build plug-ins that work with the "native" Windows GIMP.

At this time, this is all I want to do. I have no requirement to build the
app right now.

Cygwin as a tools environment on win32 is fine. The mozilla project uses a
similar setup 
and it works nicely. Tor mentions a couple of others.

The issue is not the tools, but the compiler/linker. When building on
win32, you want to 
identify this is the case and pick up a 'standard' compiler - usually
msdev, so that you 
build against the standard runtime, select appropriate compile/linker flags
and don't end 
up with Cygwin dependencies. Whether moving your entire build system to a
cross platform 
build solution is "easy" or not, remains to be seen. It is certainly
possible - evidence 
- the mozilla build system.

Regarding volunteering. No, thanks. No-one enjoys this work. It is tedious
and dull. 
Way too busy, anyway. Sorry.

interactive 
shell. 

I tried this, *finally* managed to get the thing to compile after lots more
messing 
about.

When I tried linking against an MSDEV generated openjpeg lib, I got various
linker 
errors.

I tried rebuilding OpenJPEG using MINGW/MSYS and it came up with missing
include files 
and a missing library.

I'll stick with the Cygwin dependencies for now ... at least it builds !

Next step. I'm done with messing around with overly complex makefiles and
incomplete 
tools. I'll figure out the required libraries and create an MSDEV project
file.

Well, yes.

some packages 
out there where the location of the .pc file is not
$prefix/{lib,share}/pkconfig.

Well, Unix pkg-config could be enhanced to assume a default location, which
could be 
overridden if the prefix= entry is specified in the file. That way, you
have complete 
backwards compatibility and can go through and remove the prefix= line from
.pc files, 
one at a time with testing to make sure nothing breaks. Anyone who wants a
different 
configuration (which is likely the exception) can add a prefix= line to
their local file. 
This should keep everyone happy.

> The prefix line is present in the .pc files  ....
Yuk.


Best regards,

Steve.
