2009-07-17external toolchain: check cross-compiler existenceThomas Petazzoni
As a minimal test to the external toolchain, check that $(TARGET_CC) is actually an existing executable file. That way, if the user misconfigures the toolchain path and/or prefix, a meaningful error message will be shown. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2009-07-17external toolchain: respect $(Q)Thomas Petazzoni
Use $(Q) in external toolchain support so that the user can get the full output by passing V=1 to make, and still get a nice and clean output by default. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2009-07-17external toolchain: copy the C++ standard library if neededThomas Petazzoni
Obey the BR2_INSTALL_LIBSTDCPP configuration option to copy the C++ standard library to the target. Suggested by Lionel Landwerlin <lionel.landwerlin@openwide.fr>. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2009-07-17external toolchain: do not copy useless symbolic linksThomas Petazzoni
Do not copy .so symbolic links to target when not needed. Only copy .so.X symbolic links and the library itself. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2009-07-17external toolchain: use LANG=C when calling gcc -vThomas Petazzoni
Lionel Landwerlin <lionel.landwerlin@openwide.fr> reported that using the external toolchain support when LANG=fr_FR.UTF-8 doesn't work, since the messages printed by gcc -v are translated in another language, defeating the grep ^Configured test. Therefore, as per Lionel suggestion, we force LANG=C when calling $(TARGET_CC) -v. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2009-07-17external-toolchain: better documentation, cleanup, sysroot checkThomas Petazzoni
* Introduce documentation for each function of ext-tool.mk, and document all parameters of the functions. * Pass SYSROOT_DIR as argument to all functions that require it, instead of computing it manually everywhere * Use $(shell) instead of backquotes * Check that the SYSROOT_DIR variable is not empty, which means that the external toolchain doesn't support --sysroot. In that case, bail out with a nice error message. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2009-07-16external toolchain: fix libraries copy and add ARM ABI checkThomas Petazzoni
Instead of hardcoding the C library versions, just copy the version available in $SYSROOT_DIR/lib. Add a check on the ARM ABI configured in Buildroot with regard to the ABI of the external toolchain provided. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2009-07-02toolchain/gcc: ensure libraries are copied to target_dir for x86-64Peter Korsgaard
x86-64 stores libgcc_s / libstdc++ / libgcj under lib64 instead of lib, so make sure that directory is searched as well for libraries to copy to target. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2009-06-15Improve external toolchain checksThomas Petazzoni
This patch adds some checks on the external toolchains. First, it checks that the C library selection is correct, by looking if gcc is able to find the main C library file through the -print-file-name option. Then, it attempts to check if the Buildroot toolchain options match the configuration of the toolchain : * for glibc, it checks that IPv6, RPC, locales, wide-char, large file support Buildroot options are enabled, since with glibc all these features are always available (at least this is the assumption we make) ; * for uClibc, it checks the Buildroot options with the uClibc configuration file in $SYSROOT_DIR/usr/include/bits/uClibc_config.h Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2009-06-15Simple glibc-based external toolchain supportThomas Petazzoni
The current Buildroot works just well with sysrootable glibc toolchains, using the external toolchain feature. The only thing that needs to be customized is the set of libraries that must be compiled to the target. The following patch takes a simple approach to making it easier for users to use glibc toolchains. It just adds a uClibc/glibc choice in the external toolchain menu. Then, depending on that selection, the configuration system will choose a sane default value for the library files list. The other advantage of having a uClibc/glibc choice is that in the future, we'll be able to add checks verifying that the external toolchain configuration matches the features selected in Buildroot (in terms of IPv6, RPC, locales or large file support).

They shouldn't be used anymore, needs havily patching (6.3 has more than 200k patches) and no one tests them with current toolchains.

2009-04-22toolchain/gcc: don't enable libssp supportPeter Korsgaard
It's broken anyway as we don't install libssp* into TARGET_DIR, and we should use the SSP support in uClibc if we want stack protection.

Add BR2_ENABLE_LOCALE_PURGE / BR2_ENABLE_LOCALE_WHITELIST options to remove unwanted locales from the target rootfs. Handy for stuff like the gtk stack, which comes with ~25 MB locales. Works similar to localepurge in Debian, E.G. you provide a white list of wanted locales, and everything else is removed.
