2010-12-13toolchain: rework thread optionsThomas Petazzoni
The selection of linuxthreads, linuxthreads old or NPTL doesn't make a lot of sense for external toolchains. So, instead, we : * Introduce an hidden BR2_TOOLCHAIN_HAS_THREADS option, which must be selected by toolchain specific options when thread support is available. Package needing to test thread support should use this option. * Move the none/linuxthreads/linuxthreads old/NPTL selection to Buildroot internal toolchain configuration. * Add an option in external toolchain to tell if thread support is available or not in the external toolchain. We assume that glibc without threads is not possible, as Ulrich Drepper said in http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html ffmpeg, dmalloc and openvpn are fixed to use the new BR2_TOOLCHAIN_HAS_THREADS option. For openvpn, --enable-threads=posix is no longer used, as the configure script doesn't even understand this option.

2010-07-28toolchain: remove multilibThomas Petazzoni
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 <thomas.petazzoni@free-electrons.com>
2010-07-27toolchain: Remove now-unused variablesThomas Petazzoni
The variable BR2_SYSROOT_STAGING_DESTDIR is no longer used, since now the prefix for gcc is already set to the correct location. The variable BR2_SYSROOT_TARGET_DESTDIR was already unused. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2010-07-07Rework sysroot option handlingThomas Petazzoni
The external toolchain and internal toolchain cases both need to use the --sysroot option, and they have almost identical LDFLAGS/CFLAGS/CXXFLAGS definition, so we can factorize these definitions. Moreover, the --isysroot option is implied by --sysroot so there's no need to specify both. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2010-04-11Get rid of the OPTIMIZE_FOR_CPU variableThomas Petazzoni
This variable, together with the FIXME comment, has been added has part of Eric Andersen's « Major buildroot facelift, step one » commit that occured in October 2004. Since then, no real usage has been made of OPTIMIZE_FOR_CPU, and the initial intention has probably been lost in the memories of the implementors. Therefore, get rid of the variable, and just use $(ARCH) at the two locations the variable was used. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2010-04-11Get rid of useless OpenMP related codeThomas Petazzoni
It seems that there was an intention to add BR2_ENABLE_OPENMP someday, but it was in June 2007 (commit c81807a9d71fba9f35eeb7e3f3b56bda4b2e0edd) and since then, nothing occured. Therefore, get rid of this code, and just pass --disable-openmp to gettext to keep the current behaviour. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2009-01-02toolchain: revert "Allow creating a script for external use of Buildroot ↵Peter Korsgaard
toolchain" It's been 10 days now without any reply from Ulf, so revert r24480+r24481.
2008-12-23toolchain: disable export-toolchain stuff as it breaks make dependenciesPeter Korsgaard
For some reason Ulf's export-toolchain stuff breaks the build as the dependencies target isn't executed and SED isn't set.
