* 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.

* 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| | | | | | | | The bionic libc support was out of date and relied on downloading binaries from the internet.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>

* Fix build of older Glibc using GCC >=10Nik Konyuchenko2021-06-241-0/+7
| | | | | | | | | | | | | 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>

* Add moxiebox as a choice for libcAlexey Neyman2018-12-012-1/+17
| | | | | | | | | | | | | | | | | 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.
