* 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>
* Fold libc_start_files into libcAlexey Neyman2022-02-111-4/+3
| | | | | | | | | | | | | | | | | | | | | | 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>

* Add moxiebox as a choice for libcAlexey Neyman2018-12-011-16/+6
| | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | The referenced commit replaced 'make' with '${make}' everywhere. This is wrong for at least the utilities that we may build as companion tools (make, libtool): this will always invoke the version detected by configure by supplying the absolute path. In other words, the wrappers in .build/tools/bin are not fallbacks - they are either temporary (in case a respective companion tool is built) or permanent redirectors. This is the reason why the PATH= has .build/*/buildtools/bin at higher precedence than .build/tools/bin; the latter has the versions detected by configure and the former has the versions built as companion tools. Revert the rest of the gang (grep/sed/...) for consistency. After all, we may decide to supply some of them as well (awk, for instance). Signed-off-by: Alexey Neyman <stilor@att.net>
* libc/*.sh: Deprecate libc_check_config step.Alexey Neyman2016-08-231-4/+0
| | | | | | | | | | | | | | | | | | This step was only used in uClibc. However, with upcoming multilib, the config management will have to be done for each variant differently, anyway. uClibc was the only user of libc_check_config step, as well as CT_CONFIG_DIR directory. Retire these. Two other clean-ups in uClibc.sh: - KERNEL_HEADERS check seems to be bogus, this config option is not present even in 0.9.30 - which is not supported already. - SHARED_LIB_LOADER_PREFIX was renamed to MULTILIB_DIR in 0.9.31, according to ChangeLog - and MULTILIB_DIR is passed from command line instead.

Our scripts should be consistent about using the variables that define where the found tool was found.

* xtensa: add support for the configurable Xtensa architecture.Chris Zankel2015-11-131-0/+9
| | | | | | | | | | | | | | | The Xtensa processor architecture is a configurable, extensible, and synthesizable 32-bit RISC processor core. Processor and SOC vendors can select from various processor options and even create customized instructions in addition to a base ISA to tailor the processor for a particular application. Because of the configurability, the build process requires one additional step for gcc, binutils, and gdb to update the default configuration. These configurations are packed into an 'overlay' tar image, and are simply untarred on top of the default configuration during the build. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
* gcc: Support only the latest branch releases of gccBryan Hundven2015-10-311-19/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change, as per #222, reduces the number of supported releases of gcc to the latest branch releases. I noticed while doing this work that gcc-4.5.4 was never added, so I moved patches for gcc-4.5.3 to 4.5.4 and updated the bfin-unknown-linux-uclibc example. Also, 120-siginfo.patch was fixed upstream in the 4.5.4 release, so this patch is omitted. I also bumped the avr sample to 4.9.3 from 4.9.2. With the addition of gcc-5.x, the gcc release team now releases the major.minor.0 versions, while updates to the branch are available in svn/git. We'll address that when we get to issue #219. This change just removes CC_GCC_5_1 and moves CC_GCC_5_2 to CC_GCC_5, and removes CC_GCC_5_1_or_later and moves CC_GCC_5_2_or_later to CC_GCC_5_or_later. This is the first of two part changes, as mentioned in #222. This change is slated for release in 1.22.0. The next change will be slated for 1.23.0, and will limit gcc versions to what is on https://gcc.gnu.org under "Release Series and Status", which is currently 4.9.3 and 5.2.0, although I will also support the previous supported version. In this example that would be 4.8.5. Last, but not least, this change also retires AVR32 support. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com>

* avr-libc: add support for avr-libc C libraryErico Nunes2015-06-211-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for the avr-libc C library. According to the project page at http://www.nongnu.org/avr-libc , the avr-libc package provides a subset of the standard C library for Atmel AVR 8-bit RISC microcontrollers. In addition, the library provides the basic startup code needed by most applications. Support for this library in crosstool-ng is only enabled for the AVR 8-bit target. The avr-libc manual and most distributions build the AVR 8-bit gcc toolchain with the "avr" (non-canonical) target. Some experimentation also led to the conclusion that other (canonical) targets are not very well supported, so we force the "avr" target for crosstool-ng as well. The manual also recommends building avr-libc after the final gcc build. To accomplish this with crosstool-ng, a new do_libc_post_cc step is added, in which currently only avr-libc performs its build, and is a no-op for the other libc options.

* arch/avr32: Fix download of header filesMartin Guy2013-03-311-9/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the download of the avr32 headers in crosstool-ng by fetching them directly from Atmel's web site instead of the now-broken URL given by the original author of the avr32-header-fetching modification, who fetched them from a copy on his own, now-defunct server. It also adds the necessary logic to extract from a zip file, as that is how the headers are packaged. To configure it for avr32 after launching ct-ng menuconfig in an empty directory: Paths and misc options -> Shell to use as CONFIG_SHELL = sh Target options -> Target Architecture = avr32 Toolchain options -> Tuple's alias = avr32 Binary utilities -> binutils version = 2.18a C compiler gcc version = 4.2.2 C-library newlib version = 1.17.0 Enable IOs on long long = yes Enable IOs on floats and doubles = yes Disable the syscalls supplied with newlib = yes CONFIG_SHELL is necessary to get round the "fragment: command not found" bug when binutils-2.18 is configured using bash.
