[adtools] AROS patch for gcc-core-4.2.2
- From: Josef Wegner <Josef.Wegner@xxxxxxxxxxx>
- To: adtools@xxxxxxxxxxxxx, AROS Research OS Development Mailing List <aros-dev@xxxxxxxx>
- Date: Thu, 18 Oct 2007 07:56:03 +0200
Hi,
here are some patches to create an AROS cross-compiler on i386 linux. I
was able to compile and run some simple test programs on AROS hosted.
gcc-core-4.2.2-adtools-aros.diff is a patch against the latest SVN
revision of adtools/trunk. gcc-core-4.2.2-aros.diff was made against the
gcc-core-4.2.2 release.
It would be nice if somebody could help me to complete it. Right now, I
cannot create a working native compiler.
The compilation stops at:
make[4]: *** No rule to make target `auto-build.h', needed by
`build/genmodes.o'. Stop.
make[3]: *** [all-gcc] Error 2
make[2]: *** [all] Error 2
Best regards,
-Josef
