GCC build script?

[bmarkus]

Hi,

is build script of GCC shipped available? I tried to find it with no success.

Thanks... Bela

The compilers shippped in raspbian are built from debian source packages which are available from our repository in the usual manner.

I'm not sure how the cross-compilers the foundation supply were built.

I'm trying to build GCC 4.6.3/4.7.2 in SCRATCHBOX and in CT-NG environment. After reading many blog posts, GCC manual, etc. and trying different settings still no success. I can build program binaries, but it fails building shared libraries, usually with this xgcc related error

conftest.c:1:0: sorry, unimplemented: -mfloat-abi=hard and VFP

Same with different toolchains and on Raspbian native itself. So I'm curious how it is built.

IIRC hardfloat support is a very new feature and requires some patching in release gcc versions.

Unfortunately I don't know exactly what the patches are because debian already selected and applied them. I just changed the defaults to build code suitable for the Pi.

Building 4.6.3 native on Raspbian with hardfloat now works without any patch.
