Re: cross compiling gnustep on embedded device (wince)

[Vincent R.]

Hi,

I am trying to cross-compile gnustep-make and gnustep-base and I would
have some questions and remarks/feedback in this area.

My goal is to be able to do an hello world using objective C on window
mobile device.

My current issue is the fact makefiles are adding a reference to
/usr/include and it makes
some conflict with includes from my toolchains:

address@hidden:~/projects/GNUstep/gnustep-base-1.19.1$ make
messages=yes target=arm-mingw32ce                                         

                This is gnustep-make 2.0.8. Type 'make
print-gnustep-make-help' for help.

When cross-compiling there shoudln't have -I/usr/include, in the worst
case it could be $TOOLCHAIN_ROOT/usr/include with
in my case TOOLCHAIN_ROOT=/home/vincent/opt/mingw32ce-4.4.0/arm-mingw32ce.




Thanks
