* toolchain: rework thread optionsThomas Petazzoni2010-12-136-33/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* toolchain: move Stack Protection Support optionThomas Petazzoni2010-12-133-10/+10
| | | | | | | | | | The BR2_USE_SSP option is only used inside the uClibc build, so only meaningful for Buildroot internal toolchains. Therefore, the option is moved to the right location so that it isn't visible when working with external toolchains.

* toolchain: rework C++ optionsThomas Petazzoni2010-12-137-25/+44
| | | | | | | | | | | | | | | | | | | | | | | | 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 Petazzoni2010-12-135-26/+4
| | | | | | | | | | 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: add support for external toolchain profiles and downloadThomas Petazzoni2010-12-134-92/+308
| | | | | | | | | | | | | | | | | | | Instead of letting the user define all the details of his external toolchain, we define a set of profiles for well-known external toolchains (CodeSourcery ones only at the moment, can easily be extended with other toolchains). Once a profile has been choosen, the user is offered the choice of either letting Buildroot download and install the external toolchain, or (as before) to tell Buildroot where the toolchain is installed on the system. We of course provide a "custom profile", through which the user can configure Buildroot to use a custom external toolchain for which no profile is available.

* 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: Improve C library option selectionThomas Petazzoni2010-12-134-47/+172
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Turn BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, BR2_USE_WCHAR, BR2_ENABLE_LOCALE and BR2_PROGRAM_INVOCATION into hidden options. Then, for Buildroot toolchains, external toolchains and Crosstool-NG toolchains, provide visible options that selects the hidden options. This allows : * To show a different label and help text in the case of Buildroot toolchain (do you want to enable feature X ?) and in the case of external toolchain (is feature X available in your toolchain ?) * To not show any option when a glibc external toolchain is selected (since glibc is assumed to support all of largefile, IPv6, RPC, WCHAR, locale and program invocation) and have them all selected in that case. There is some amount of duplication between Buildroot toolchain config options and Crosstool-NG toolchain config options, because kconfig doesn't allow to source the same Config.in file twice (even if under mutually exclusive conditions). This duplication is more readable that the hack that consists in splitting files in multiple pieces. However, this commit changes the name of the options visible in the configuration interface, so existing .config files will have to be updated accordingly.

* strip path when untaring kernel for headersPaulius Zaleckas2010-12-131-2/+3
| | | | | | | | | | | | This is needed when custom/snapshot kernel headers are selected. Buildroot expects to find dl/linux-2.6.tar.bz2 and also expects it to extract to output/toolchain/linux-2.6, but if you tar custom kernel sources directory can be anything, etc. linux-git. In that case buildroot would extract it to output/toolchain/linux-git. So fix this behaviour, by using tar strip-directory/component.
