gcc: move /lib* symlink handling up to gcc-intermediate

2010-07-30T08:02:23Z

The /lib* symlinking added by 3c77bab2eeace needs to be moved up to the gcc-intermediate step now the NPTL stuff is merged, otherwise 64bit builds fails (lib64 already created). Signed-off-by: Peter Korsgaard

toolchain: enforce --disable-multilib

2010-07-30T07:31:39Z

Since 5575d205c (toolchain: remove multilib) we were no longer passing --disable-multilib, which broke builds for multilib-capable archs (like x86-64, ppc, ..). Signed-off-by: Peter Korsgaard

toolchain: mark uClibc 0.9.31 + locale + C++ as broken

2010-07-29T20:18:57Z

uClibc: remove old 0.9.28 support

2010-07-29T15:02:29Z

Not supported upstream and needs complicated workaround for the NPTL stuff. Signed-off-by: Peter Korsgaard

Add support for uclibc NPTL toolchain.

2010-07-29T14:57:00Z

This patch modifies current toolchain build sequence so that NPTL enabled toolchain can be built. The new sequence works well with linuxthreads as well. It introduces a new pass for gcc cross compilation. The new sequence is binutils->gcc-initial->linux-headers -> uclibc-configured (some cheats to generate phony shared libc.so and libm.o) -> gcc-intermediate(with shared lib support) -> uclibc -> gcc-final I also added a new sample config arm_nptl_toolchain_defconfig which builds the toolchain and busybox. I have only tried it on arm. However it should work for other architectures which support NPTL on uclibc e.g. mips, sh, x86, ppc, x86_64 Signed-off-by: Khem Raj Signed-off-by: Peter Korsgaard

gdb: disallow GDB_HOST on external toolchain builds

2010-07-29T14:04:38Z

The cross-gdb is supposed to be part of the external toolchain, so Buildroot does not need to build it. Moreover, GDB_HOST build currently fail with: ln -snf ../../bin/arm-unknown-linux-gnueabi-gdb \ /home/test/outputs/test-48/staging/usr/arm-unknown-linux-gnueabi/bin/gdb ln: creating symbolic link `/home/test/outputs/test-48/staging/usr/arm-unknown-linux-gnueabi/bin/gdb': No such file or directory And even worse: they overwrite the cross-gdb of the external toolchain!

dependencies: add svn as a mandatory tool

2010-07-29T14:04:38Z

Now that two packages (tremor and libsvgtiny) are being downloaded from svn, svn becomes a mandatory tool to run Buildroot. Signed-off-by: Thomas Petazzoni

toolchain: remove multilib

2010-07-28T21:21:45Z

Supporting multilib is much more than just passing --enable-multilib to gcc. You have to actually build the C library several times (once for each multilib variant you want to support in your toolchain), and to pass MULTILIB_OPTIONS/MULTILIB_EXCEPTIONS values to gcc to let it know the set of multilib variants you're interested in. Since we'll probably never support multilib toolchains in Buildroot, just get rid of this BR2_ENABLE_MULTILIB option. Signed-off-by: Thomas Petazzoni
