* Support standalone LLVM/Clang as crosscompilerAlfred Persson Forsberg2023-08-221-0/+20
| | | | | | | | | | | | | | | | | | | | | | This change makes it possible to use Clang instead of GCC in Crossdev. As LLVM is already able to target other architectures, provided that LLVM_TARGETS is set accordingly, the only thing needed to do is compile builtins (compiler-rt) for the target triple. Note that compiler-rt needs libc headers to target when building, and in turn linux-headers needs to be installed for Linux targets, so most stages except binutils and GCC are still there. Currently having both a GCC and LLVM Crossdev environment installed for the same triple is not supported since many ebuilds just use /usr/${CTARGET} as a hardcoded sysroot, but I plan adding support. Note: by standalone I mean a pure LLVM toolchain not dependent on an existing GCC toolchain.

* crossdev, emerge-wrapper: request EAPI=7 on eclass importsDavid Seifert2021-06-211-1/+1
| | | | | | | | | | | | | | | | | | | Today ::gentoo dropped support for EAPI=0 from multilib.eclass and toolchain-funcs.eclass. Due to lack of error handling on crossdev side srossdev derived wrong environment for $CTARGET (and mostly fell back to CHOST). This caused at best failing early on gcc-stage1 build. At worst crossdev installed libraries into a wrong $(get_libdir), installed symlinks from wrong host and other disasters. Previous crossdev commits make crossdev crash earlier instead of generating wrong environment. This commit allows dropping EAI=0 support for eclasses eventually.

* wrappers/emerge-wrapper: fail crossdev setup when toolchain-funcs.eclass ↵Sergei Trofimovich2021-06-211-1/+3
| | | | | | | | | | | | | | | | | | | sourcing fails Before the change toolchain-funcs.eclass import failure did not fail hard and generated suboptimal default ARCH. It's not as bad as crossdev's equivalent 'multilib.eclass' source failure, but still not perfect. The change exposes die() calls to be visible in crossdev run: ``` $ rm -rf '@GENTOO_PORTAGE_EPREFIX@/usr/foo/etc'; ./emerge-wrapper --target foo --init emerge-wrapper: ERROR: toolchain-funcs.eclass: EAPI 0 not supported emerge-wrapper: ERROR: Failed calling 'tc-arch' from toolchain-funcs.eclass. ``` Reported-by: Marco Scardovi (scardracs) Bug: https://bugs.gentoo.org/797367 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>
* wrappers/emerge-wrapper: drop population of profile/package.providedSergei Trofimovich2019-08-301-10/+0
| | | | | | | | | | 'profile/package.provided' is created empty for quite a while because wrapper init is called before any cross-* package gets merged. Let's drop that completely and focus on always installing headers and libc into target. Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

| | | | | | | | | | | | Need for make.defaults: portage does not allow ARCH override in make.conf anymore Need for use.force: embedded profile enforces linux target on us.

| | | | | | | | | | | The crossdev code had a more full-featured parser of the repos.conf output than the emerge-wrapper. The latter failed to include the last overlay in the list leading to ugly warnings like: /usr/bin/emerge-wrapper: line 48: /eclass/toolchain-funcs.eclass: No such file or directory /usr/bin/emerge-wrapper: line 49: tc-arch: command not found URL: https://bugs.gentoo.org/546748 Signed-off-by: Mike Frysinger <vapier@gentoo.org>
