* debug: provide an option to copy the gdbserver to the targetThomas Petazzoni2012-03-151-0/+14
| | | | | | | | | | | | | | When an external toolchain is used, it is very likely that it contains a pre-built version of a gdbserver that has the same version as the cross-gdb included in the external toolchain. So, we now provide an option that allows to copy this pre-built gdbserver to the target. As the location of the gdbserver in the external toolchain is not standardized, we only support the CodeSourcery and Crosstool-NG layouts for the moment. Other locations can be added later.

| | | | | | | | | | | Without the -m64, choosing the x86_64 architecture with a Sourcery external toolchain will result in a 32-bit rootfs. Also simplified the help text to reflect this change.

* external-toolchain: add support for Linaro 2012.01Thomas Petazzoni2012-03-012-4/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linaro has just released a new pre-built toolchain, available as a tarball, which is a pure toolchain (only the C library is included). This makes this new Linaro 2012.01 toolchain usable in Buildroot, so let's integrate the support for it. In addition to simply adding the new external toolchain at the usual locations, this patch allows need to adapt a few things to support Linaro toolchains. Most toolchains store their libraries in the "lib/" or "usr/lib" directories relative to the toolchain. Buildroot toolchains on the other hand, store the libraries in the "usr/<target-name>/lib" directory. And the Linaro toolchain has choosen to use the "lib/<target-name>" directory. Therefore, this patch adjust: * The logic to search a particular library when that library needs to be copied to the target directory * The logic to deduce the sysroot directory from the libc.a file location in the toolchain: removing "(usr/?)lib(64?)" is no longer sufficient, we need to take into account the "lib/<target-name>/" case. Since the Linaro toolchain generates code for Cortex-A processors only, the selection of this toolchain is limited to Cortex-A8 and Cortex-A9.

* external-toolchain: run checks even on extracted toolchainsThomas Petazzoni2012-03-011-4/+2
| | | | | | | | | | | When the mechanism that allows Buildroot to download external toolchains automatically was added, all the sanity checks on the external toolchains were not performed. This commit re-enables those checks that we already do on external toolchains that are not downloaded/extracted by Buildroot. This makes the toolchain checks more consistent accross various configurations. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

* Expand external toolchain wrapper to custom flagsThomas Petazzoni2012-03-012-0/+11
| | | | | | | | | | The BR2_TARGET_OPTIMIZATION flags were not used by the external toolchain wrapper, which broke the multilib selection logic of multilib external toolchains.

* Improve external toolchain logic to support IA32 Sourcery CodeBench toolchainThomas Petazzoni2012-03-011-13/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IA32 Sourcery CodeBench toolchain has a relatively special structure, with the following multilib variants: * Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to the main sysroot, with the libraries in the lib/ directory. * Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative to the main sysroot, with the libraries in the lib64/ directory. * Intel Atom 32 bits, the multilib variant is in atom/ relative to the main sysroot, with the libraries in the lib/ directory. * Intel Core 2 64 bits, the multilib variant is in core2/ relative to the main sysroot, with the libraries in lib64/ directory. So the first two variants are in the same sysroot, only the name of the directory for the libraries is different. Therefore, we introduce a new ARCH_LIB_DIR variable, which contains either 'lib' or 'lib64'. This variable is defined according to the location of the libc.a file for the selected multilib variant, and is then used when copying the libraries to the target and to the staging directory. In addition to this, we no longer use the -print-multi-directory to get the ARCH_SUBDIR, since in the case of the 64 bits variants of this toolchain, it returns just '64' and not a real path. Instead, we simply compute the difference between the arch-specific sysroot and the main sysroot. We also take that opportunity to expand the documentation on the meaning of the different variables.

* gdb: fix kconfig dependency handling with !BR_TOOLCHAIN_BUILDROOTPeter Korsgaard2011-11-241-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer versions of GDB need pthread debugging support if threads are enabled, which is always the case for glibc but is a configure option for uClibc. We have solved this for internal toolchains by selecting the BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this option isn't available when ctng/external toolchains are used, mconf prints ugly warnings and the build may fail if an external uClibc toolchain without pthread debugging support is used. Fix it by introducing 2 more hidden config options: - BR2_TOOLCHAIN_HAS_THREADS_DEBUG - BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED The first tells us if the toolchain HAS pthreads debugging support, and is checked by check_uclibc_feature in helper.mk for external uClibc based toolchains. The second tells us if the toolchain is ABLE TO provide pthreads debugging support if threads are enabled, either because it's an internal toolchain where we can force enable it or an external glibc/eglibc toolchain or uClibc with the option enabled. Crosstool-ng forcibly enables this support, so those will always work. The preconfigured uClibc-based toolchains we have also all enable it. Finally, show a comment if this isn't the case so the (external toolchain) user knows why. This is placed outside the choice option, as menuconfig has a bug where it doesn't show choice selections which only contain comments. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

| | | | | | | | | | | | | Some CodeSourcery toolchains contain a huge number of locales that are not useful, even though they account for 70-80% of the total toolchain size. By skipping the extraction of those useless locales, we make the toolchain extraction process slightly faster, and also make the output directory size a lot smaller (host/opt/ is 213 MB instead of 1.5 GB with a 2010.09 ARM CodeSourcery toolchain).
