* Cleanup old avr-libstdcxx code and make it usable on other targetsQBos072024-12-231-2/+2
| | | | | | | | | | Should not cause major unwanted behavior changes - C++ is now selected by default in many configs. Signed-off-by: QBos07 <qubos@outlook.de> [cp: depend on CC_LANG_CXX instead of select] Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Disable implicit-function-declaration error for newlibNik Konyuchenko2024-05-181-0/+3
| | | | | | | | | GCC14 will treat implicit-function-declaration as an error by default. See https://gcc.gnu.org/gcc-14/porting_to.html for details. Some libc function like __trap34 are defined in assembly and break this GCC diagnostic. Signed-off-by: Nik Konyuchenko <spaun2002mobile@gmail.com>

* glibc: Add option for building libcryptChris Packham2023-08-251-0/+4
| | | | | | | As of glibc-2.38 libcrypt is not built by default. Add an option to allow building libcrypt support into glibc. Signed-off-by: Chris Packham <judge.packham@gmail.com>
* Add option to re-enable ˋlibstdc++ˋ on avr targets.Quentin Boswank2023-08-141-18/+50
| | | | | | | | | | | Due to the small flash space on AVR devices the library containing the standard types in C++ (ˋlibstdc++ˋ) does not get built normally when enabling the C++ language support. This option is an easy way to go back to the PC-way where ˋlibstdc++ˋ is built. Signed-off-by: Quentin Boswank <qubos@outlook.de>

* picolibc: Add configuration to select picolibc as the system libcJoakim Nohlgård2023-03-081-0/+29
| | | | | | | 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>
* glibc: configure adding debug symbols in glibc buildGuillermo E. Martinez2022-06-211-1/+5
| | | | | | | | | | 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.

* glibc: Reinstate support for the bundled portsChris Packham2022-05-181-0/+3
| | | | | | | | | | | 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 Packham2022-05-101-34/+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>
* Unify core passesAlexey Neyman2022-02-111-1/+1
| | | | | | | | | 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). Signed-off-by: Alexey Neyman <stilor@att.net>
* Fold libc_start_files into libcAlexey Neyman2022-02-117-335/+79
| | | | | | | | | | | | | | | | | | | | | | After 557b9d4, libc_start_files and libc_main steps are performed one after another. It doesn't make sense, especially since some of the libcs (glibc, uClibc-ng) go to great lengths to first install start files in the first step, libc_start_files, only to remove them immediately in the second step, libc_main. Current build steps also break in the xtensa newlib configurations, as it needs to install the custom xtensa headers before building the libgcc and after 557b9d4, the headers are not installed before libgcc is built in pass-1. Therefore, finish what 557b9d4 mentioned but did not do: move header installation into a new step, libc_headers, and combine libc_start_files and libc_main into a single step. This also allows to combine the core pass-1/pass-2 steps, to be done in a subsequent commit. Signed-off-by: Alexey Neyman <stilor@att.net>
* Retire obsoleted milestonesAlexey Neyman2022-02-112-41/+23
| | | | | | | | | | | | ... 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>
* Fix build of older Glibc using GCC >=10Nik Konyuchenko2021-06-241-0/+4
| | | | | | | | | | | | | 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>

* glibc: set glibc build system default_cflags emptyHans-Christian Noren Egtvedt2020-10-051-0/+2
| | | | | | | | | | By setting glibc build system default_cflags to be empty before building, we will enforce the build system to only use the crosstool-ng CFLAGS when building glibc. Properly solves the issue identified in #1396. Signed-off-by: Hans-Christian Noren Egtvedt <hegtvedt@cisco.com>

* Add moxiebox as a choice for libcAlexey Neyman2018-12-019-137/+163
| | | | | | | | | | | | | | | | | This required some rework of the libc selection, as moxiebox is a layer on top of another libc - newlib. Also, moxiebox'es host VM (`sandbox`) needs a libcrypto on the host. We will not have it if we're cross-compiling a canadian cross. Fortunately, all moxiebox needs from libcrypto is SHA256, and it already includes a standalone implementation of SHA256 in its runtime. Provide a little wrapper that allows moxiebox use that implementation for the host binary, too. Also, automate collecting/printing the list of all packages in a given category (e.g. LIBC or COMP_TOOLS), generate a list of all Kconfig symbols for a given category.
