classes/recipes: Switch virtual/XXX-gcc to virtual/cross-cc (and c++/binutils)

2025-01-21T23:09:33+00:00

The idea of the base class dependency is to say "yes, I need a C cross compiler" and this was never meant to be gcc specific. Looking at the codebase, whilst we code triplets into this, it does overcomplicate things as there are only ever limited, "target", "sdk" and the class extended versions like mutlilib. After much thought, we can simplify this to virtual/cross-cc and virtual/nativesdk-cross-cc. This lets us remove the "gcc" specific element as well as removing the over complicated triplet usage. At the same time, change the much less widely used "g++" variant to "c++" for similar reasons and remove the triplet from virtual/XXX-binutils too. Backwards compatibility mappings could be left but are just going to confuse things in future so we'll just require users to update. This simplification, whilst disruptive for any toolchain focused layers, will make improved toolchain selection in the future much easier. Since we no longer have overlapping variables, some code for that can just be removed. The class extension code does need to start remapping some variables but not the crosssdk target recipe names. This patch is in two pieces, this one handles the renaming with the functional changes separate in a second for easier review even if this breaks bisection.

gcc: unify cleanup of include-fixed, apply to cross-canadian

2024-08-03T06:56:10+00:00

Since target and cross variants were already doing similar cleanup of include-fixed headers, as those aren't used, unify the code and also apply the same to cross-canadian variant. Some of those header files get processed with a tool that leaves absolute buildpaths inside the file's commented section, causing QA errors. Since those aren't used, let's remove them. This may be a temporary solution until the tool itself gets fixed to not embed absolute buildpaths in the header files: https://lists.openembedded.org/g/openembedded-core/topic/107268307 (From OE-Core rev: 9221e4ab8cca4c06dc3d5c1de2fd4ce46477578a) Signed-off-by: Denys Dmytriyenko Signed-off-by: Richard Purdie

gcc: remove paths to sysroot from configargs.h and checksum-options for gcc-cross-canadian

2024-08-03T06:56:10+00:00

Apply fixes from gcc-cross (84a78f46d594 and 0ead8cbdfb96) to gcc-cross-canadian. This will improve (but not fix) reproducibility of gcc-cross-canadian. Also move this code to functions to avoid code duplication. [RP: Tweak patch to make the function parameters clear and fix quoting issues ensuring the code exactly matches the original replacements with an additional parameter.] (From OE-Core rev: 350ff7d53f7506de2bc01f0efc569b8294b9afea) Signed-off-by: Oleksandr Hnatiuk Signed-off-by: Denys Dmytriyenko Signed-off-by: Richard Purdie

gcc: Allow using libc++

2024-06-12T15:57:19+00:00

With the addition of the C++ runtime setting added recently, allow gcc to use libc++ as its runtime. There's some minor fixes still required, such as allowing setting the unwinder library. But this allows for testing libc++ with gcc.

gcc/go: Drop crosssdk suffix from virtual provides to improve dependency handling

2023-05-02T09:24:50+00:00

There is little point in having "crosssdk" suffex added to the virtual provider within gcc/go since the TARGET_PREFIX or SDK_PREFIX already encapsulates this. Remove it allowing some of the special case overriding to be removed. This also allows removal of some of the MLPREFIX usage since again, the triplet also covers this.

gcc-cross-canadian: add default plugin linker

2022-09-17T06:47:07+00:00

Fix multilib sdk issue where gcc is unable to find linker. Previous fix was in cdd86896c8d29135f937968e9aa07f919cf543d3 using real-ld symlink, but that prevented switching between bfd and gold linkers. Running compiler with debug arguments shows that collect2 tries and fails to find linker using the multilib triples: $ $CC -v -Wl,-debug ... Looking for 'real-ld' Looking for 'collect-ld' Looking for 'mips-oemllib32-linux-ld' Looking for 'mips-oe-linux-mips-oemllib32-linux-ld' ... collect2 version 12.2.0 ld_file_name = not found ... collect2: fatal error: cannot find ‘ld’ Using --with-plugin-ld=ld in gcc-cross-canadian builds to set default linker name for collect2, lets it find the linker correctly: Looking for 'real-ld' Looking for 'collect-ld' Looking for 'ld' ... collect2 version 12.2.0 ld_file_name = /usr/local/oecore-x86_64/sysroots/x86_64-oesdk-linux/usr/libexec/mips-oe-linux/gcc/mips-oe-linux/12.2.0/ld Swith between bfd and gold linker works as expected now: $ $CC -v -Wl,-debug -fuse-ld=gold ... Looking for 'real-ld' Looking for 'collect-ld' Looking for 'ld.gold' ... collect2 version 12.2.0 ld_file_name = /usr/local/oecore-x86_64/sysroots/x86_64-oesdk-linux/usr/libexec/i686-oe-linux/gcc/i686-oe-linux/12.2.0/ld.gold (From OE-Core rev: cf1bb16b7f9f81514feaf1e4ecffd9039387bb89) Signed-off-by: Samuli Piippo Signed-off-by: Richard Purdie

Revert "gcc-cross-canadian: Add symlink to real-ld alongside other symlinks"

This reverts commit cdd86896c8d29135f937968e9aa07f919cf543d3. real-ld is always used if that is found, which means you cannot switch between bfd and gold linkers using -fuse-ld gcc option.

gcc-cross-canadian: Fix cross canadian compiler for baremetal targets

2022-01-12T07:19:35+00:00

While building GCC it checks whether the include directory exists, if it doesnt it throws an error and exits: | The directory that should contain system headers does not exist: | tmp/work/x86_64-nativesdk-pokysdk-linux/gcc-cross-canadian-riscv32/ 11.2.0-r0/recipe-sysroot/usr/include/ | make[1]: *** [Makefile:3257: stmp-fixinc] Error 1 Even though for the baremetal toolchain not having this directory does make sense. We overcame this by removing the --with-sysroot=/not/exist argument for baremetal toolchains (via TARGET_OS override), however, the newlib toolchain does have headers and an includedir, hence by fixing the baremetal toolchain we broke the newlib one since it uses the same TARGET_OS as baremetal, causing for example (on newlib): /sdk/sysroots/x86_64-pokysdk-linux/usr/lib/riscv32-poky-elf/gcc/ riscv32-poky-elf/11.2.0/include/stdint.h:9:16: fatal error: stdint.h: No such file or directory | # include_next ^~~~~~~~~~ compilation terminated. By creating a dummy includedir, and removing the previous fix we allow GCC to be built the same way, unifying the cross compiler for all targets. After this fix both TCLIBC=baremetal and TCLIBC=newlib SDKs work properly.
