* glibc: Turn implicit-int back into warningChris Packham2024-10-151-2/+2
| | | | | | | | | | As of GCC14 implicit-int has been upgraded to an error. While this is generally a good idea it trips up some older code (particularly in autoconf generated configure scripts). Add -Wno-implicit-int to CFLAGS for glibc when using an old GLIBC with a new GCC. Fixes #2208 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* improve a workaround for a glibc and GNU make incompatibilityCharles Baylis2024-09-141-1/+1
| | | | | | | | | | | | | | | Versions of GNU make newer than 4.4 trigger a hang in versions of glibc older than 2.31. In e63c40854c977f488bee159a8f8ebf5fc06c8666, this was fixed when the host platform provided make >= 4.4. However, if the host distro provides only an ancient version of make, crosstool-ng would still build make 4.4 as a comp tool, which would fail to build glibc. Extend the previous workaround to build make 4.3 when building old glibc versions which require it. See also: #1946 Signed-off-by: Charles Baylis <cbaylis@fishzet.co.uk>
* musl: Mark not EXPERIMENTALChris Packham2024-05-241-1/+0
| | | | | | | | | | | | | Musl was marked experimental in commit 08d91d41 ("musl: config is broken for !EXPERIMENTAL"). Most of the reasoning for that change no longer applies and as it's been about 8 years it's time to let musl loose on the world. Drop the `depends on EXPERIMENTAL` and update the sample configs for aarch64 and x86_64. For powerpc64 the ABI needs to be elfv2. Enforce this via the powerpc config. Add a sample configuration for powerpc-unknown-linux-musl. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* glibc: Disable -Werror for GCC14Chris Packham2024-05-181-1/+1

* Revert "libc/uclibc: Require GCC12 or older"Chris Packham2023-08-131-1/+0
| | | | | | | | This reverts commit 5427dac45c12f6be8e3fca7bc38b9abcebb4ec87. The issues that were causing this have been resolved with some updates so allow the uclibc+gcc13 combination again. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* provide a workaround for a glibc and GNU make incompatibilityChris Packham2023-07-211-0/+9
| | | | | | | | | | | Versions of GNU make newer than 4.4 trigger a hang in versions of glibc older than 2.31. As distros update to the newer GNU make version we'll start seeing more and more reports of this hang. Fortunately we already carry GNU make as a comp tool so all we need to do is select the right version when needed. Fixes #1946, #1932, #1975 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* newlib: add 4.3.0.20230120Chris Packham2023-06-041-0/+1

* picolibc: Allow default memory layout values to be configuredKeith Packard2023-04-191-0/+40
| | | | | | | | 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>
* picolibc: Add configuration to select picolibc as the system libcJoakim Nohlgård2023-03-081-0/+125
| | | | | | | This moves the picolibc configuration values under C-library -> picolibc so that they will be more easily discovered. Signed-off-by: Joakim Nohlgård <joakim@nohlgard.se>
* newlib: fix conflicting configure optionsChen Tao2022-06-281-0/+24
| | | | | | | | | | Configuring the newlib with "--enable-newlib-nano-formatted-io" and "--enable-newlib-io-pos-args" would cause built GCC cannot compile some IO functions like "std::cout". And I added additional notes at Nano Formatted I/O config. Signed-off-by: Chen Tao <t.clydechen@gmail.com>
* glibc: configure adding debug symbols in glibc buildGuillermo E. Martinez2022-06-211-0/+7
| | | | | | | | | | After building the cross toolchain and compile a simple C program, objdump reports debug information even though -g modifier was not used. These debug segments are in glibc library and CRT files. So a new config entry: CT_GLIBC_ENABLE_DEBUG was added to control when we want to add debug information to glibc, by default is enabled. Signed-off-by: Guillermo E. Martinez <guillermo.e.martinez@oracle.com>
* glibc: rework GLIBC_ENABLE_WERRORChris Packham2022-05-311-5/+6
| | | | | | | | | | Use `depends on` conditions to enable/disable building glibc with -Werror. Using `depends on` instead of `default if` means that when the GCC/GLIBC selection changes GLIBC_ENABLE_WERROR will automatically become n. Fixes #1729, fixes #1712 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* glibc: Reinstate support for the bundled portsChris Packham2022-05-181-0/+9
| | | | | | | | | | | Commit 6d5227b6 ("Remove obsolete glibc 2.12.1") removed supports for the separate glibc-ports but also removed GLIBC_USE_PORTS_ADDON. Glibc versions up to 2.20 bundled support from some architectures in the ports directory so GLIBC_USE_PORTS_ADDON is required to support these older glibc versions. Fixes #1736 Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Remove obsolete glibc 2.12.1Chris Packham2022-05-101-17/+0
| | | | | | | | | glibc 2.12.1 was marked as obsolete. Now that the 1.25.0 release is out this version can be removed completely. As glibc 2.12.1 was the last remaining version supported by glibc-ports support for glibc-ports is also removed. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Remove obsolete bionic/android supportChris Packham2022-05-101-127/+0
| | | | | | | | The bionic libc support was out of date and relied on downloading binaries from the internet. It was already marked as obsolete. Now that the 1.25.0 release is out it can be completely removed. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* glibc: Enable -Werror for more combinations of GCC/GLIBCChris Packham2022-05-011-2/+8
| | | | | | | | | | | Newer GCC versions trigger warnings on older GLIBC versions. GLIBC 2.29 is warning free with GCC9. GLIBC 2.31 is warning free with GCC10. GLIBC 2.34 is warning free with GCC11. Add milestones for 2.31 and 2.34 and use those to set the default value for GLIBC_ENABLE_WERROR based on the GCC version. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* bionic: mark bionic/android-ndk as obsoleteChris Packham2022-02-231-0/+1
| | | | | | | | | | Support for bionic was dropped by GCC some time ago. There are patches for older GCC versions but those are difficult to maintain and the version of the android-ndk they support is of little use. Mark all of the existing bionic support as obsolete so it can be removed after the next release. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Unify core passesAlexey Neyman2022-02-116-6/+6
| | | | | | | | | With libc_headers step before pass-1, there is no need to distinguish pass-1 and pass-2; they are configured identically (note that with the current configuration, core pass-2 is only used for win32 - hence, uses build_libgcc=yes and mode=static).

* Retire obsoleted milestonesAlexey Neyman2022-02-114-94/+4
| | | | | | | | | | | | ... and the code dependent on them, after the latest wave of obsolete package removals. 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". I opted in favor of giving uClibc-ng the recognition it deserves, although it had some ripple effect in the ct-ng code. Signed-off-by: Alexey Neyman <stilor@att.net>
* glibc: Re-enable WerrorChris Packham2022-01-121-3/+0
| | | | | | | | | | | | Now that we have a 2-pass build it is no longer necessary to disable -Werror in glibc. This partially reverts commits 6ca5f91f ("Disable -Werror for GLIBC for all ARCH for GCC11."), 215432d3 ("config/libc: Extend glibc 2.32 workaround to include sparc") and 645ee124 ("glibc: Don't build with -Werror for powerpc64+glibc-2.32").

* gcc: Build static libgcc in core_pass1Chris Packham2022-01-125-7/+5
| | | | | | | | | | | | | | | | | | Per https://github.com/crosstool-ng/crosstool-ng/issues/808 build static libgcc in the first pass which lets us skip the second one. Building mingw-w64 requires header files in order to build C++ support so mingw builds core pass 2. This could probably be cleaned up by splitting libc_start_files into a separate libc_header step. But for now having core 2 for mingw-w64 and core 1 for the other libcs will have to do. Anything that previously selected CC_CORE_PASSES_NEEDED now selects CC_CORE_PASS_1_NEEDED. The same goes for CC_CORE_PASS_2_NEEDED with the exception of mingw-w64. Fixes #808 Fixes #217 Signed-off-by: Chris Packham <judge.packham@gmail.com>

| | | | | | | | | | | | | Issue #1535 GCC 10 changed the default to -fno-common, which leads to a linking error in GLibc older than 2.30. This change adds -fcommon cflag for the target GLibc versions <=2.29 and GCC >=10. This change also adds additional cflags for the target GLibc to disable new GCC11 checks that lead to compilation errors. Signed-off-by: Nik Konyuchenko <spaun2002mobile@gmail.com>
