[openbeos] Re: Building on Linux

I know it's way too early for this, but I'd actually be interested in seeing some form of benchmarks for common Haiku operations between the old GCC for R5 compat and GCC4 on x86.

I'm sure I'm not the only one.

Anyone have any idea if the difference is even noticeable?

I'm having some trouble building the Haiku build tools on Linux. I've
checked out the buildtools from subversion, and followed the instructions in
INSTALL-as-cross-compiler-on-LINUX up until make cross:

I've tried this on a regular i686 with the same result.

Can anyone give me some pointers where to go?  Is this a bug in the

I suppose the documentation has not been adjusted to the fact that Ingo has
moved the legacy buildtools into the 'legacy' folder, such that the main
folder contains gcc-4 while gcc-2.95.3 lives in legacy.
Unless I'm mistaken, you can follow the docs, but take care to execute the
stuff in the legacy folder. This should build gcc-2.95.3 as a cross-compiler,
which is what you will need if you want to execute the resulting binaries on
The other (upper) gcc folder that contains gcc-4 is currently only intended
for PPC builds (Ingo, please correct me if needed). We should make this a bit
clearer I suppose, at least in the docs, but maybe in the repository
hierarchy, too.

Yep, I've never updated the docs within the buildtools folder. The ReadMe in the haiku module is up to date though, and letting the configure script build the cross tools is easier anyway.

Regarding gcc4, it should work for both x86 and PPC builds. In case of x86 the resulting Haiku installation will just not be binary compatible with BeOS R5.

CU, Ingo
