2017-02-03uclibc: allow to build aarch64 internal toolchainWaldemar Brodkorb
uClibc-ng from 1.0.22 and up supports aarch64 architecture. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
2017-02-03uclibc: enable mips{32,64}r6 supportWaldemar Brodkorb
The config for ISA choice is removed for a long time as the buildsystem does not pass -march=mips* to the compiler anymore. For mips{32,64}r6 support NAN selection is required. Tested with qemu mips32/mips64 defconfigs. A small patch is required. Bug found while testing qemu defconfigs.

2017-01-25arch: add OpenRISC architecture supportWaldemar Brodkorb
Add support for OpenRISC. See here for more details about OpenRISC http://openrisc.io. All buildroot included upstream binutils versions are supported. Gcc support is not upstream, to be able to enable musl C library support later, we use the branch with musl support. At the moment it is possible to build a musl based toolchain, but bootup in Qemu fails. Gdb is only working to debug bare-metal code, there is no support for gdbserver/gdb on Linux, yet.

2016-08-22musl: enable mips64 supportWaldemar Brodkorb

2016-08-19toolchain-buildroot: allow to build ppc64(le) musl toolchainsWaldemar Brodkorb
Latest musl release supports ppc64 architecture (both big endian and little endian), so this commit adds support for this. Since musl implements the ELFv2 ABI for both big-endian and little-endian PowerPC64, we have to force using this ABI on PowerPC64 big endian (normally elfv1 is the default). Also, only gcc 6.x has the necessary changes to support musl on PowerPC 64, so we restrict the gcc version selection accordingly. Tested with Qemu for big endian and little endian configurations.

2016-06-28Replace (e)glibc by glibcThomas Petazzoni
Following the removal of eglibc support, this commit replaces all occurences of "(e)glibc" by just "glibc". Most of the occurences are in package Config.in comments. In addition, when the form "an (e)glibc ..." was used, it is replaced by "a glibc ...".

2016-04-08toolchain-buildroot: don't show musl on noMMU platformsThomas Petazzoni
While musl has recently gained noMMU support for the sh2 platform, we don't support this yet. So for the time being, let's not show musl as an available C library on noMMU platforms.

2016-03-08toolchain: also source the musl packageYann E. MORIN
We do source the glibc and uClibc packages in the toolchain menu, because they do provide user-visible options. However, we do not so far source the musl Config.in file However, in 822be87 (toolchain: include C libraries in legal-info), a Config.in file for musl was explicitly created, so that: - legal-info would work (needed at the time, probably no longer needed nowadays), - the appropriate packages are enabled, like netbsd-queue or kernel headers. Yet, we do not source musl/Config.in, which means we do not get netbsd-queue or kernel-headers to be selected: $ make distclean; make menuconfig Toolchain ---> C library ---> musl save-and-exit $ grep BR2_PACKAGE_LINUX_HEADERS .config [nothing] $ grep BR2_PACKAGE_NETBSD_QUEUE .config [nothing] Fix that by sourcing musl/Config.in at the same place we source glibc and uClibc. Normally, we do have a check in place that verifies that a package that is not enabled is not a dependency of another package that is enabled. However, musl is only a dependency of host-gcc-final, which is a host package and has no corresponding BR2_PACKAGE_HOST_GCC_FINAL. Thus host-gcc-final is not in the PACKAGES variable, and thus does not trigger our check. Reported-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com> Signed-off-by: "Yann E.

2015-05-03sh4: fix toolchain creationWaldemar Brodkorb
The Linux kernel does force compile with -m4-nofpu, which is only available when building a multilib toolchain. The interesting part here is, that buildroot use --disable-multilib for gcc configure, but enables --with-multilib-list=m4,m4-nofpu in the default configuration for Qemu targeting r2d emulation. This results in a toolchain, which can be used for the kernel and for userland without creating a multilib toolchain with different kinds of libgcc version. In the multilib case there would be subdirectories created (!m4 and m4-nofpu). As buildroot uses a short version of toolchain creation, a multilib enabled gcc build fails when creating libgcc. So the best solution is to just keep multilib disabled, but always add --with-multilib-list when sh4/sh4eb/sh4a/sh4aeb is choosen. Tested with sh4/sh4a toolchain build and qemu defconfig with gcc 4.8.x/4.9.x (with and without C++ enabled), uClibc and glibc. Disable sh4a/sh4aeb for uClibc, as it does not implemented, yet.

2014-12-11Rename BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBSThomas Petazzoni
Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed from "prefer static libraries when possible" to "use only static libraries". The former semantic didn't make much sense, since the user had absolutely no control/idea of which package would use static libraries, and which packages would not. Therefore, for quite some time, we have been starting to enforce that BR2_PREFER_STATIC_LIB should really build everything with static libraries. As a consequence, this patch renames BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS, and adjust the Config.in option accordingly. This also helps preparing the addition of other options to select shared, shared+static or just static. Note that we have verified that this commit can be reproduced by simply doing a global rename of BR2_PREFER_STATIC_LIB to BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.
