* Use more sensible names for the external/ctng targetsThomas Petazzoni2013-07-041-9/+7
| | | | | | | | | Instead of using the 'uclibc' target for all toolchain backends, introduce more sensible target names for the external toolchain and Crosstool-NG toolchain backend make targets.

* toolchain/crosstool-NG: do not depend on the top-level Buildroot's .configYann E. MORIN2013-03-181-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, the crosstool-NG backend did depend on the top-level Buildroot's .config to detect changes in the toolchain options, using a tentatively-clever heuristic, which also included the full Buildroot's version string to push down to set the components' versions strings. In doing so, any commit in the Buildroot tree would imply a complete rebuild of the toolchain, even in the case the toolchain options did not change, thus being a large annoyance (to say the least). As Buildroot never guaranteed that toolchain options would be detected, even less handled, and that the internal backend does neither detect nor act on toolchain options changes, and delegate that to the user, there is no point in individualising the crosstool-NG backend's behaviour. This reasoning also applies to the depdency on the crosstool-NG's bundled .config file, too. So, just drop the not-so-clever heuristic, and just build the toolchain once, leaving to the user the responsibility to explictly ask Buildroot to rebuild the toolchain.

* toolchain/crosstool-ng: vendor part of tuple should be 'buildroot'Thomas Petazzoni2012-10-181-1/+1
| | | | | | | | | | | | | | | | | | | Since 11017f081fc5b034e680d89eaea729c19f450e01, the Crosstool-ng backend generates toolchains that have a prefix inconsistent with what Buildroot expects. Buildroot expects a "buildroot" vendor name, while Crosstool-NG builds toolchain with the "unknown" vendor name. This is causing build failure such as: http://autobuild.buildroot.org/results/15b2c0e50a81b86dd13af684c9254df2bc0df8de/build-end.log Fix this by changing the vendor part of the tuple used by Crosstool-NG to "buildroot".

| | | | | | | | | | | | Move crosstool-NG to package/ and make it an autotarget package. This requires a new patch (now upstream). Now, the crosstool-NG toolchain backend only contains enough to build the toolchain, there's no more reference to building crosstool-NG as a package. Signed-off-by: "Yann E.

| | | | | | | | | | | | | On "make source", just download the required sources, and do not build the entire toolchain. This requires a new patch against crosstool-NG (got from upstream). The "uclibc-source" rule requires an installed and configured crosstool-NG, so it has to be after the variables declaration. For consistency, move down the main rule "uclibc". Signed-off-by: "Yann E.

* toolchain/crosstool-NG: fix up ct-ng config file to saner defaultsYann E. MORIN2011-05-221-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | Peter on IRC reported some build failures for different targets. They were of two kinds: - missing/unknown stack unwinding support - missing *_chk functions The first is about configure not being able to automagically determine if stack unwinding support is available for the target. The second is about fortified build forgetting to build the fortified functions. This applies to both glibc and eglibc. After some discussions on IRC with Jacmet, it appears that we can safely assume both of the following: - virtually all targets of buildroot will have stack unwinding support - we do not care about fortified builds (so far) So, update the bundled crosstool-NG .config file to saner defaults: - force unwind support - disable fortified builds [Peter: fix 'force non-fortified build' sed invocation] Reported-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: "Yann E.

* toolchain/crosstool-NG: correctly copy the dynamic linkerYann E. MORIN2011-04-241-3/+4
| | | | | | | | | | | | | | | | | Depending on some setting (which? Arch? Others?), the dynamic linker can get different names. Some times, it is named ld-linux.something.so, other times, it is ld.so.1, and maybe other variants as well... The fix is to always copy ls*.so, even if it is a symlink: we create the destination file by its SONAME, and if ld*.so matches more than one file, that's no issue, as they would all get the same SONAME (being symlinks ones to the others).

| | | | | | | | | | | | | | | | | | | | | | | | 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.).
