2022-02-23bionic: mark bionic/android-ndk as obsoleteChris Packham1-0/+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>
2022-02-11Unify core passesAlexey Neyman6-6/+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). Signed-off-by: Alexey Neyman <stilor@att.net>

2022-02-11Retire obsoleted milestonesAlexey Neyman4-94/+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>
2022-01-12glibc: Re-enable WerrorChris Packham1-3/+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").

2022-01-12gcc: Build static libgcc in core_pass1Chris Packham5-7/+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>
2021-11-30glibc: Add comment about python 3.4 dependencyChris Packham1-0/+3

2021-06-24Fix build of older Glibc using GCC >=10Nik Konyuchenko1-0/+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>

2018-12-01Add moxiebox as a choice for libcAlexey Neyman2-1/+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.

2018-01-30More fixes after the upgrades:Alexey Neyman1-0/+5
- GLIBC requires a fix to work with binutils 2.30 on aarch64. This fix relies on binutils 2.24 or newer, which is okay for glibc 2.26 since it needs 2.25 or newer anyway. But older glibc versions are now pinned to binutils 2.29 or older on aarch64. - xtensa needs patches in libgcc with gcc 7.3. - comment in newlib's patch to indicate it is a reversal of a commit.
