toolchain-external: fix bfin external toolchain download

2013-07-11T05:14:44+00:00

Fixes http://autobuild.buildroot.org/results/7d0/7d0eee796407880a4554474e5affbe98b8caa271/ Commit 1cbffbd (eliminate double slashes caused by FOO_SITE ending in a slash) added a double replacement for the special bfin external toolchain download, breaking it. Fix it by removing the 2nd replacement. Signed-off-by: Peter Korsgaard

toolchain: disable C++ support on AVR32 gcc 4.2 with uClibc

2013-07-08T21:10:29+00:00

In 25c3160092d7 ("uClibc 0.9.31: remove stray kludges/conditions"), a conditional that prevents the combination gcc 4.2-avr / C++ / locale with uClibc 0.9.31 was removed. However, it turns out that the same problem is affecting uClibc 0.9.33, described at http://comments.gmane.org/gmane.comp.lib.uclibc.buildroot/24260. Therefore, we prevent the combination of gcc 4.2-avr / C++ / locale to happen. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

Make the microblaze toolchains easily distinguishable

2013-07-08T21:09:49+00:00

It was confusing to have two different toolchains with the same label. Signed-off-by: Jan Viktorin Acked-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

eglibc: enable support in the Buildroot toolchain backend

2013-07-04T09:08:27+00:00

Using the newly introduced 'eglibc' package, this commit enables the option of building a toolchain using the eglibc C library in the Buildroot toolchain backend. In details, this commit: * Creates a choice to select uClibc or eglibc in the Buildroot toolchain backend (in toolchain/toolchain-buildroot/Config.in), and removes the fact that the Buildroot toolchain backend forcefully enables uClibc (toolchain/Config.in). * Creates a BUILDROOT_LIBC variables, which points to the package implementing the C library (i.e either 'uclibc' or 'eglibc'). * Modifies the gcc-final and gcc-intermediate makefiles to use the BUILDROOT_LIBC variable instead of hardcoding the use of uclibc. * Ensures that TLS support is always enabled when building eglibc.

uclibc: move configuration options into the package

2013-07-04T08:33:56+00:00

In preparation for the introduction of the eglibc library to the internal toolchain backend, the options that allow to enable/disable C library features such as largefile, IPv6, RPC and so on now belong to the uClibc package. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

Introduce BR2_TOOLCHAIN_USES_{UCLIBC, GLIBC}

2013-07-04T07:08:42+00:00

Currently, when we need to do a conditional on the type of C library used, we need to take into account the three toolchain backends. As we are going to add eglibc support to the Buildroot toolchain backend, it would become even uglier, so this patch introduces two new hidden options: BR2_TOOLCHAIN_USES_UCLIBC and BR2_TOOLCHAIN_USES_GLIBC, that exist regardless of the toolchain backend. The entire Buildroot code base is converted to use those options. Note that we have intentionally created only one option (BR2_TOOLCHAIN_USES_GLIBC) for both glibc and eglibc, since they are essentially the same, as far as Buildroot is concerned.

Use more sensible names for the external/ctng targets

2013-07-03T22:14:10+00:00

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. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard
