Well, in a nutshell, you have to know what you are doing;) Short instructions:
Most importantly, the plug-in obviously must not use some POSIX-only
or Linux-only APIs that are not available in the C library on Windows.
You will need the header files for GIMP and the ones they include
(GTK+ and its dependencies), and import libraries for the DLLs that
the plug-in uses. (If you don't know what an import library is, look
in the interweb.)
As far as I know there is no distribution of a GIMP 2.4 developer
package for Windows, unfortunately. But I think it should work fine to
use headers and import libraries from GIMP 2.2, so get
(I will shortly create a developer package for GIMP 2.4 and add a link
to it on the http://www.gimp.org/~tml/gimp/win32/downloads.html page.)
Unzip the developer package in some suitably named new, empty folder.
You will also need developer packages for GTK+, Pango, atk and glib.
Unzip them, too, in either the same, or separate folders.
With Visual Studio: set up a project that compiles the plug-in's
source file(s), and pass the correct -I flags to the compiler so that
it finds the header files, and the correct /libpath switches to the
linker so that it finds the import libraries, and link with the
correct libraries (the same ones you link with on Linux).
With MSYS: Basically do like on Linux. If you are using auto* and
libtool on Linux (as you should), but have never used those on Windows
before, it can be a pain to set them up. So maybe for a small, perhaps
just a single source file, program like a GIMP plug-in you shouldn't
bother. Just write a makefile from scratch that builds your plug-in.
One thing you need to watch out for is the correct order of object (or
source) files and -L and -l options on the command line. The
non-traditional order allowed by gcc and ld on Linux don't work for ld
To find out what the correct compiler and linker flags are, you can
use the gimptool-2.0.exe program distributed with the gimp developer
package. It requires that you also have the pkg-config program
(available from the downloads.html web page mentioned above) and the
PKG_CONFIG_PATH environment variable correctly set up, so if that
causes a headache to you, it might be easier to just write the
makefile from scratch.
You can use gimptool-2.0.exe also to find out the flags for the
Microsoft compiler and linker. Just pass the --msvc-syntax flag to
gimptool-2.0.exe. (But see above about pkg-config and
So, in a nutshell, this is not rocket science. It's simply a matter of
invoking the compiler with the right flags. I suggest staying away
from tools like dev-cpp that try to make things easier but only
succeed in preventing you from learning how things actually work.
Dev-cpp etc might be fine for Your First Hello World program, but once
you get past that, you need to get your fingers dirty. Feel free to
disagree, of course.
