* wrappers: mipsel-linux-gnu: fix ac_cv_type_uid_t cache value20240209Sam James2024-02-091-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Reported by matoro when building coreutils for mipsel-unknown-linux-gnu. If autoconf-2.72 is used, apparently this shows up, and the coreutils-9.4 dist tarball was indeed built with it... The symptoms are similar to bug #885485 but it's a different cause -- we were exporting a dodgy cache value with a missing '$': ``` configure:14771: checking for uid_t configure:14771: result: {ac_cv_type_uid_t=yes} ``` ``` ac_cv_type_uid_t='{ac_cv_type_uid_t=yes}' ``` ``` $ rg ac_cv_type_uid_t wrappers/site/mipsel-linux-gnu:115:ac_cv_type_uid_t={ac_cv_type_uid_t=yes} ``` Bug: https://bugs.gentoo.org/885485 Signed-off-by: Sam James <sam@gentoo.org>

* cross-pkg-config: Set PKG_CONFIG_FDO_SYSROOT_RULES=1Matt Turner2023-10-151-0/+3
| | | | | | | | | | | When cross-compiling, pkgconf behaves in a way that causes many packages to install files to ${SYSROOT}/${SYSROOT}/... without PKG_CONFIG_FDO_SYSROOT_RULES set. I'm aware of at least gobject-introspection, modemmanager, and libp11, but there are likely more. Signed-off-by: Matt Turner <mattst88@gentoo.org>

* cross-pkg-config: Properly set PKG_CONFIG_SYSTEM_*_PATH variables20230923James Le Cuirot2023-09-231-1/+3
| | | | | | | | | | | | | | | | | | | | | | Perhaps this was a difference between pkg-config and pkgconf, but we have not set PKG_CONFIG_SYSTEM_LIBRARY_PATH correctly since we began setting it in 2014. It should include the SYSROOT. We also never set PKG_CONFIG_SYSTEM_INCLUDE_PATH at all. These variables tell pkg-config not to emit paths that the toolchain would search in anyway. This helps to reduce the noise appearing in newly-installed .pc files. This change does assume that if you have set SYSROOT differently to the toolchain's default, then you have also added the --sysroot argument to your compiler flags. Neither Portage nor Gentoo currently do this for you. cross-boss does, but it's not an officially supported solution. The change could therefore potentially break things, but it's likely you'll run into other problems if you don't add --sysroot anyway.

* Support standalone LLVM/Clang as crosscompilerAlfred Persson Forsberg2023-08-223-49/+215
| | | | | | | | | | | | | | | | | | | | | | 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.

* wrappers: fix mipsel-linux-gnu cache vars for *sys_siglist20230209Sam James2023-02-091-3/+3
| | | | | | | | | | | | | sys_siglist was removed from glibc-2.32. Before now, for mipsel-linux-gnu, we were forcing the cache var to 'yes', rather than 'no'. I suspect this test would've worked correctly even without caching anyway, but it is what it is. Default to 'no' instead of 'yes'.

| | | | | | | | | | | | | | | | | | | | | | | Follow-up to 8b1b79e02cc36bc6f2b5583db6aeea333fb8d59b. Sets ``` ac_cv_func_malloc_0_nonnull=yes ac_cv_func_realloc_0_nonnull=yes ``` ... to sort out flex and a bunch of other packages, like procps. I was wondering why this never seemed to come up when doing cross for other "standard" targets which we know work and are used often; the answer is that we never had the -musl suffix CHOSTs covered. (e.g. linux-gnu already has this set.)
