hello,
I use eclipse cdt (5.0) to build plugins for X-Plane (shared libs). I
have CDT set up and running on WinXP, Linux and OS X 10.4 PPC.
One final piece is missing: the shared lib created on OS X seems to be
powerPC only and I need it to be cross-plattform PPC+Intel = universal
binary.
Looks like I have to specify the two platforms as target for GCC but I
cannot figure out where in the CDT project settings I have to put this
options.
(so far I used xcode on this mac to build universal but I'd rather like
use CDT to be consistent across all three platforms)
thanks

hi,
finally I got around to try this. But I get an error
Invoking: GCC C Compiler
gcc -DAPL=1 -O0 -g3 -Wall -c - fmessage-length=0 -arch ppc -arch i386
-MMD -MP -MF"SimDataSender/SimDataSender.d"
-MT"SimDataSender/SimDataSender.d" -o"SimDataSender/
SimDataSender.o" "../SimDataSender/SimDataSender.c"
gcc: -E, -S, -save-temps and -M options are not allowed with multiple
-arch flags
So the next question: how to get rid of those -Msomething flags? I see
nothing in the eclipse build configuration that relates to those flags.
(using CDT Ganymede M1 by now)
An ideas?
thank you
Jens

Nope.. I use CMake and let Eclipse use the makefiles generated from
that. I would say look deep in the compiler options flags.
