toolchain/gcc: the ARC version of gcc needs host-flex/host-bison

2013-05-12T20:22:18Z

For some reason (probably because the ARC changes modify some lex/yacc files without updating their pre-generated variants, or because the date/time of the pre-generated files is not correct), building the ARC gcc requires host-flex and host-bison. We have tested 4.2 for AVR, 4.3 and 4.4 for ARM, and none of those need host-flex or host-bison to be installed, so only the 4.4 for ARC seems to be affected.

toolchain/gcc: make sure to pass $(HOST_DIR)/usr/bin in the PATH

2013-05-12T20:22:00Z

Since gcc doesn't use the package infrastructure, it doesn't get all the good generic environment variables, and forgets to get $(HOST_DIR)/usr/bin in its PATH. This prevents gcc from finding and using host tools built by Buildroot. This patch therefore ensures that $(HOST_MAKE_ENV) or $(TARGET_MAKE_ENV) are passed at the appropriate locations. It will be useful for a later patch that makes gcc depend on host-flex/host-bison in some situations. Original patch by Thomas Petazzoni.

toolchain-external: fix bug #5054

2013-05-11T19:52:22Z

The external toolchain logic checks (and finds) the proper ARCH_LIB_DIR and forcibly copies it to */lib even if it's in */lib64 This is all well until the check is done for create_lib64_symlinks which only verifies if ARCH_SYSROOT_DIR/lib64 is a symlink, which in some toolchain it's a real directory (like sourcery x86_64 2012.09) and thus doesn't make the symlink in the target. Fix this by also checking for a real directory. Easily reproducible by running "make qemu_x86_64_defconfig", switching to an external toolchain before build, building and then trying to run the resulting image.

toolchain/crostool-NG: mark as deprecated

2013-05-07T21:01:09Z

For the following reasons: - it used to be broken without anyone noticing for a long time, - it is still not fully integrated within the Buildroot set of options, - it has not gained much traction (not even I use it), - I've always argued that sustained development should use an external toolchain, and not rely on building one with Buildroot, - I did not submit any of the enhancements requested during the last developpers' day in Brussels, - I have neither the incentive nor the time to maintain and enhance it, it is time to deprecate the crosstool-NG backend for the 2013.05 release. Then, it will be entirely removed early in the 2013.08 cycle, to let some time for those that rely on it to voice their opinions. ;-) Signed-off-by: "Yann E.

toolchain/gcc: Enable --with-float for powerpc

2013-05-06T10:29:34Z

Commit 8d929f4b ("toolchain/gcc: Only enable --with-float when it makes sense") restricted the --with-float use to only MIPS, ARM and SPARC, while it seems that powerpc needs it as well. Fixes the qemu_ppc_virtex_ml507_defconfig build. Signed-off-by: Maxime Ripard Signed-off-by: Peter Korsgaard
