There shouldn't be any X dependencies in the cairo backend code apart from the X surfaces of course. You should be able to provide your own MS Windows surface and use that. This gets a bit harder on the make file level, here our config scripts currently only support the cairo backend for X11. There is one other problem I see, although freetype is available for Windows you will most likely want to use native font support. For this you will need to implement your own classes or port the ones from the the winlib backend. Out of curiosity, why do you want to use cairo on Windows and not the native window interface (or one based on GDI+)? When I have more time (who knows when that will be!) I will take a deeper look and try to figure out everything that needs to be done to enable the Cairo backend on Windows. On a side note, I've heard that there are plans for a theming API, but I've had some difficulty finding any details. Where could I find out about that? There already is some limited theming available in GNUstep. You find the API and the code for it in gui/Source/GSTheme.m.

Re: gnustep on windows
Hello Some months (a year ?) ago i tried to write a Cairo backend for windows. You can get the files there : http://amstradstuff.free.fr/GNUstep/back-win32cairo.zip Put then in Source/cairo directory Achtung : two files will be overwritten !! I'm not sure they still can be build as cairo backend has been changed but they may be a first step. You will need FreeType and fontconfig.

Apparently, I may be wrong about this. The problems with Opterons are probably something completely different, and ffcall apparently does work on them (at least as much as GNUstep needs). I'm still interested in peoples' experiences with libffi on Opterons, though. -- Hubert Chathi - Email/Jabber: [EMAIL PROTECTED] - http://www.uhoreg.ca/ PGP/GnuPG key: 1024D/124B61FA (Key available at wwwkeys.pgp.net) Fingerprint: 96C5 012F 5F74 A5F7 1FF7 5291 AF29 C719 124B 61FA ___ Gnustep-dev mailing list Gnustep-dev@gnu.org http://lists.gnu.org/mailman/listinfo/gnustep-dev
GNUstep-make and C++ projects...
Is it possible to use GNUstep-make for just plain old C++ projects
with no other involvement with GNUstep?
I tried making a ctool, and I get linker errors when I try.
My stuff looks like this:
include $(GNUSTEP_MAKEFILES)/common.make
CTOOL_NAME = LogTest
LogTest_CC_FILES = source.cc
include $(GNUSTEP_MAKEFILES)/ctool.make
#include iostream
int main (int argc, char *argv)
{
std::cout foo std::endl;
return 0;
}
and the error I get is:
Making all for ctool LogTest...
Linking ctool LogTest ...
/usr/lib/gcc/i486-linux-gnu/4.1.2/../../../../lib/crt1.o: In function
