gcc3 build breakage

[andreasf]

The following configuration on OpenSolaris host used to work: gcc 3.4.3 + cross-gcc4

haiku/trunk/headers/build/os/BeBuild.h#L43 chokes on gcc3 now though.

Can't we infer from __GNUC__ > 2 that the gcc4 ABI is to be used?

[andreasf]

The following snippet in UserBuildConfig works around this, with the gcc-dev-4 cluster installed:

HOST_GCC_RAW_VERSION = 4.3.2 ;
HOST_CC = gcc-4.3.2 ;
HOST_C++ = g++-4.3.2 ;
HOST_LINK = g++-4.3.2 ;
HOST_LIBSUPC++ = ;

...but unfortunately only for the ppc boot CD. For ppc and x86 haiku-image I get relocation errors. This happens both with gcc 3.4.3 plus patch and with gcc 4.3.2.

IMO the host compiler shouldn't mind the target Haiku ABI. Some parts of BeBuild.h are only valid for the target Haiku. You could probably add where applicable:

#ifdef HAIKU_TARGET_PLATFORM_HAIKU

Replying to korli:

This is about build/os/BeBuild.h.

If you feel like adding details, please create a new ticket. Closing this one. I've adjusted build/os/BeBuild.h in hrev34717.

Thanks Ingo, this fixes the initial part.

Opened #5158 for the follow-on errors.
