* 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.).

* toolchain: remove toolchain-specific strippingThomas Petazzoni2010-12-131-9/+0
| | | | | | | | | | We already handle the stripping of libraries in $(TARGET_DIR) at the global level, so there's no need to have toolchain-specific option and code for this.

* toolchain: remove ending semi-colon in helpersThomas Petazzoni2010-12-131-4/+4
| | | | | | | | | | | Some helpers had their final line ending with a semi-colon, some did not. For consistency, remove the final semi-colon from all helpers, it's the responsability of the caller to add the final semi-colon as needed.

* toolchain: fix helpers for POSIX complianceYann E. MORIN2010-09-301-4/+4
| | | | | | | | Using two '=' for string comparison is a bashism. Revert to using one, as stated in POSIX 1003.1-2008. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
* toolchain: move helper functions from external toolchainYann E. MORIN2010-07-281-0/+244
The helper functions used for external toolchains may also be useful to alternate toolchain backends (currently, the external toolchain is the sole user). Signed-off-by: Yann E. MORIN <yann.morin.1998@anciens.enib.fr> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
