* gcc-config: add basic version sorting supportv2.2Sergei Trofimovich2020-01-124-3/+42
| | | | | | | | | | | | | | | | Before the change gcc version orderig was relying on bash sorting in flob matches, like: cat /etc/env.d/gcc/${CHOST}-* | fgrep LDPATH | tail -n 1 This stopped working with gcc-10, which lexicographically goes before gcc-9. The workaround for now is to normalizeversions to fixed-width and order them lexicographically: gcc-0009 gcc-0010 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* gcc-config: Ignore PATH set in profile files.Arfrever Frehtes Taifersar Arahesis2019-09-081-0/+18
| | | | | | | | | | | Profile files created by toolchain.eclass before gentoo commit 534e0f7d5e8a02264b7b7fc97c3ef11441e35c5c contain assignment of PATH variable (e.g. PATH="/usr/x86_64-pc-linux-gnu/gcc-bin/9.2.0"). Sourcing them without restoring previous PATH value breaks gcc-config.

* Revert "gcc-config: store gcc backup into /lib/gcc-backup, not /lib"Sergei Trofimovich2019-09-074-80/+4
| | | | | | | | | | | | | This reverts commit 44570a44be60a8fc33bd05089047c1f2980b3047. Unfortunately ld.so does has static set of fallback paths when it fails to lookup shared library from ld.so.cache: those are /lib64 and /usr/lib64 on amd64. Let's revert the change and jkeep relying on /lib64 for now. Bug: https://bugs.gentoo.org/667020 Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* gcc-config: store gcc backup into /lib/gcc-backup, not /libSergei Trofimovich2019-09-074-4/+79
| | | | | | | | | | | | | | | Writing (and removing) libraries to /lib outside package manager was a surprise to users in bug #667020# where libunwind.so was clobbered by gcc-config runs. This change isolates all logic that handles file copies outside package manager into /lib/gcc-backup directory. To make new library still resolveable we install env.d entry with contents of LDPATH="/lib/gcc-backup" Signed-off-by: Sergei Trofimovich <slyfox@gentoo.org>

* Convert binary wrapper to a symlink wrapper.v2.0Sergei Trofimovich2018-08-248-414/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before the change: /usr/bin/gcc and friends were a copy of /usr/$(libexecdir)/misc/gcc-config After the change: /usr/bin/gcc is a symlink to a real compiler binary. Examples: /usr/${CTARGET}/gcc-bin/${GCC_VER}/gcc (native) /usr/${CHOST}/${CTARGET}/gcc-bin/${GCC_VER}/gcc (cross) gcc-config is a binary wrapper that does (or did) a few things: - [removed in 2011] injects additional CFLAGS_${ABI} Removed in commit 7ac40f3eb8434961f70485247d883f5b3009dcf2 "Stop auto appending CFLAGS_<abi> from the env." - traverses PATH for real compiler binary and reexecutes it. - reads /etc/env.d/05gcc-${CTARGET} as a fallback if PATH is empty. Today binary wrapper does only PATH resolution and re-execution. This change has a few minor benefits: - PATH will not contain explicit /usr/${CHOST}/${CTARGET}/gcc-bin/${GCC_VER} entry. This will make PATH shorter for those who have mavy cross-compilers installed. - compiler switch will not require sourcing '. /etc/profile' as changes are applied as soon an symlink is switched. - ccache will see gcc binary changes directly and react accordingly. Previously in default configuration ccache cache depended on state of /usr/$(libexecdir)/misc/gcc-config See bug #640958 where ccache did not notice USE=-pie -> USE=pie switch. - Reasoning about PATH ordering is straightforward: all available binaries (as symlinks) are in /usr/bin. See bug #255695 where PATH ordering changed and bug #626606 where people get confused on what is in /usr/bin/gcc binary.

| | | | | | | | | The intention of commit cfbb9e94ca23c360d5801946e39da29c7d422dfc was to disable running ldconfig and updating ld.so.conf for prefix, but the implementation was too greedy and also disabled env-update, which we need to activate a compiler, see bug #641096.

* gcc-config: prefix: copy GCC's libs to emulate ld.so.conf magicFabian Groffen2013-01-121-0/+234
| | | | | | | | | | | | | Because Prefix doesn't have ld.so.conf magic in place (either because it doesn't exist, or because we don't have the privileges to touch it), we need to ensure that GCC's libs can be found at runtime. To do so, we use a special dir in which we stack all GCC's libs per version. This dir is in RPATH (or equivalent), such that applications and libraries can find their libgcc_s.so.1 (needed on Solaris) or libstdc++.so.6, or libgomp.so, ... etc. Signed-off-by: Fabian Groffen <grobian@gentoo.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | Don't consider linking, even if /usr would be split, on Prefix. Do cleanup from older gcc-config though. This leaves a gap where we don't cleanup if the Prefix install uses a different filesystem for its /usr, but that should be pretty rare, non-standard and utterly weird, so we don't care.

* gcc-config: drop Solaris special casing with /lib/cppMike Frysinger2013-01-011-1/+0
| | | | | | | | | | | | | | When we added this logic, Gentoo/prefix wasn't a standard setup. Now that we do have Gentoo/prefix, there's no reason to special case Solaris as this path won't be an issue (as prefix systems don't write to /lib/). If someone really cares about using portage in a non-prefix setup, we can talk about how best to support things then. But this issue isn't Solaris specific, so we shouldn't have that tuple hardcoded.
