* gdb: fix kconfig dependency handling with !BR_TOOLCHAIN_BUILDROOTPeter Korsgaard2011-11-241-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* ext-toolchain: fix ct-ng as external rsync issuesGustavo Zacarias2011-11-021-1/+1
| | | | | | | | | | | When using a CT-NG toolchain as external toolchain (not with the integration) and said toolchain has u-w directories rsync fails. So instruct rsync to chmod u+w directories in the target copy to avoid the issue.

* toolchain: speed up sysroot lib copyingMike Frysinger2011-10-101-3/+2
| | | | | | | | | | | | | | | | The copy_toolchain_lib_root helper searches the entire sysroot, but is only interested in files in certain subdirs. So rather than waste time in walking the entire tree, walk the few subdirs at the depth level we are actually going to be poaching files from. Some simplification suggested by Yann E. MORIN <yann.morin.1998@anciens.enib.fr> and Arnout Vandecappelle <arnout@mind.be>, added by Thomas Petazzoni <thomas.petazzoni@free-electrons.com>.

* external toolchain: slightly optimize the copy of the toolchain sysrootThomas Petazzoni2011-10-091-1/+4
| | | | | | | | | | | | The sysroot of an ARM CodeSourcery toolchain takes about 1.4 GB of space, but 1.1+ GB of this space consists in locale-related information which Buildroot doesn't use. By skipping the copy of those unused files, we save quite a bit of time while importing the toolchain sysroot.

* uClibc: drop BR2_PROGRAM_INVOCATION optionPeter Korsgaard2011-07-271-2/+0
| | | | | | | | | | | | Remove the BR option and enable the configuration setting in the uClibc defconfigs. The BR2_PROGRAM_INVOCATION option only adds very little overhead to uClibc, and we have a number of packages needing it, so simply always enable it - Simplifying the kconfig logic and the number of choices users have to make.

* external-toolchain: fix supportThomas Petazzoni2011-05-081-4/+13
| | | | | | | | | | | | | | The recent commit adding the external toolchain wrapper has broken the support for external toolchain. The check_arm_eabi, check_cplusplus and check_cross_compiler_exists functions were using TARGET_CC, which points to the toolchain wrapper, but at the moment those functions are called, the wrapper hasn't been generated yet. We fix this by passing to these functions the path to the C or C++ compiler they should use for their tests.

* toolchain: fix multilib symlink for external toolchainsThomas Petazzoni2010-12-211-1/+1
| | | | | | | | | | ARCH_SUBDIR is a shell variable, so it should be referenced with $${ARCH_SUBDIR}. Without this, no symbolic link is created, and the external toolchain fails to work if the non-default multilib variant is used.

* toolchain: check that the thread option selection is correctThomas Petazzoni2010-12-131-1/+2
| | | | | | | | | | | When an external toolchain is used, the user is responsible for telling Buildroot what the configuration of the toolchain is. In order to make sure that the selection is correct, we already perform checks against the configuration of the uClibc in the selected external toolchain. This commit adds the check for thread support. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* toolchain: rework C++ optionsThomas Petazzoni2010-12-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Instead of having BR2_GCC_CROSS_CXX and BR2_INSTALL_LIBSTDCPP, with BR2_GCC_CROSS_CXX not being visible (and therefore being useless), let's just keep BR2_INSTALL_LIBSTDCPP to enable C++ in the toolchain and install C++ libraries on the target. We also take that opportunity to make BR2_INSTALL_LIBSTDCPP an hidden option, which is selected by an option in Buildroot toolchain support or an option in External toolchain support, just as we did for other toolchain features. Some work definitely remains to be done : - The name BR2_INSTALL_LIBSTDCPP is ugly, but we keep it for the moment in order to avoid changing all packages. - We should clarify the other language-related options (Fortran, Java, Objective-C, etc.).
