* picolibc: Avoid build system headersChris Packham2025-01-051-0/+1
| | | | | | | | | | When building picolibc as a companion library the configure step can end up picking up certain headers from the build system which causes build failures. Pass an appropriate --with-headers= to the GCC back end when building picolibc as a companion library so that the correct headers are detected by ./configure.

* companion_libs: zstd: Build nomt configurationChris Packham2024-09-091-1/+1
| | | | | | | | | | | | | We have been building the multi threaded zstd target. This requires that anything that links with lzstd also links with lpthread. On more recent systems this is fine because lpthread is part of GNU libc so the -pthread option is a no-op but on other systems this will cause GCC to either fail to build or to silently disable zstd compression. By building the libzstd.a-nomt-release we can be compatible with older GCC versions and ensure that support for zstd is not silently dropped. Fixes: #2198 Signed-off-by: Chris Packham <judge.packham@gmail.com>

* gnuprumcu: Pass host sysroot to build toolchainDimitar Dimitrov2024-03-111-1/+18
| | | | | | | | | | | | | | | | | | | | | | In canadian builds, the target toolchain running on the build machine is not compiling and installing target Newlib. Thus it cannot by itself link target executables. This results in errors for gnuprumcu package when its configure script attempts to test the compiler: .../ld: cannot find crt0.o: No such file or directory configure:3738: error: C compiler cannot create executables Fix by passing the host toolchains's sysroot in target CFLAGS. While at it, also add a missing passing of target LDFLAGS. Successfully tested the following canadian builds: x86_64-unknown-linux-gnu,pru x86_64-w64-mingw32,pru arm-unknown-linux-gnueabihf,pru Signed-off-by: Dimitar Dimitrov <dimitar@dinux.eu>

* newlib: Add missing linker options for nano.specsYuriy Kolerov2023-05-101-1/+1
| | | | | | | | Old options %(newlib_nano_link) for the linker must be passed otherwise linking may fail. E.g., in case of multilib configurations a correct emulation mode may be not passed. Signed-off-by: Yuriy Kolerov <ykolerov@synopsys.com>
* picolibc: Allow default memory layout values to be configuredKeith Packard2023-04-191-0/+4
| | | | | | | | These values are used when constructing the default linker scripts used with picolibc. Setting reasonable defaults allows simple test applications to be compiled without additional configuration. Signed-off-by: Keith Packard <keithp@keithp.com>

* Enable support for building libgccjitMarc Poulhiès2022-12-186-5/+39
| | | | | | | | | | | | | | | | | | | | | libgccjit is still under development and, despite its name, may also be used for ahead-of-time compilation. Documentation can be found on the gcc website: https://gcc.gnu.org/onlinedocs/jit/internals/index.html https://gcc.gnu.org/wiki/JIT With this change it's possible to enable the building of the libgccjit. It's enabled as a language (with --enable-languages=jit) even if not a language frontend at all. The main changes are related to the requirement of having everything host side built as Position Independent Code (PIC) with --enable-host-shared. GCC has the needed logic for building its dependencies (mpc, gmp, mpfr, ...) correctly when built "in-tree", which is not the case with crosstool-ng (see https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=05048fc29f0) Signed-off-by: Marc Poulhiès <dkm@kataplop.net>
* gmp: Set CC_FOR_BUILD and CPP_FOR_BUILDChris Packham2022-05-311-2/+5
| | | | | | | | | When GMP is being "cross" compiled for the same architecture (i.e. build == host) it does not pick the right compiler. Set CC_FOR_BUILD and CPP_FOR_BUILD to override the default compiler. Fixes #1328 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* newlib-nano: Fix include path for CT_NEWLIB_NANO_INSTALL_IN_TARGETStephanos Ioannidis2022-05-121-1/+1
| | | | | | | | | | | | | | | | | | When `CT_NEWLIB_NANO_INSTALL_IN_TARGET=y`, the `nano.specs` file emitted by the newlib-nano build script contains an invalid include path, resulting in the full `newlib.h` being included instead of the nano `newlib.h` by the application. `=/include/newlib-nano` is not a valid path (`=` does not mean anything and that string is taken as an include path as-is) and GCC ignores this include path, resulting in application including the `newlib.h` from `include/` which contains the newlib build configurations for the full newlib. This commit modifies the newlib-nano build script to emit a proper newlib-nano include path relative to the `GCC_EXEC_PREFIX`. Signed-off-by: Stephanos Ioannidis <root@stephanos.io>

This concludes the glorious history of the original uClibc (non-NG) with lots of kludges removed. There was a choice here, whether to call the resulting libc "uClibc" or "uClibc-ng".

| | | | | | | | | | | This commit adds a new config that can be used to specify the target CXXFLAGS specific to the libstdc++ newlib-nano variant. By default, this config is set to specify the `-fno-exceptions` option, which disables C++ exception handling support and greatly reduces the compiled binary size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In currently generated top-level "nano.specs" we resolve paths during toolchain building and then use those pre-defined full paths once the toolchain got built. That's OK until the toolchain is used right were it was built, otherwise paths used in the top-level "nano.specs" become irrelevant and linker fails to find "nano" libs reverting to non-"nano" libs in the default location.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | If existing board's .specs are used for linking of a user's application, then instead of normally used libs like libc.a & libstdc++.a might be requested their "nano"-suffixed siblings: libc_nano.a, libstdc++_nano etc. That way: ----------------------------->8--------------------------- %rename link_gcc_c_sequence myboard_link_gcc_c_sequence *myboard_libc: %{!specs=nano.specs:-lc} %{specs=nano.specs:-lc_nano} *link_gcc_c_sequence: %(myboard_link_gcc_c_sequence) --start-group %G %(myboard_libc) --end-group ----------------------------->8--------------------------- Our companion newlib-nano libs are all built optimized for size, so we'd like to use them for linking.
