Michael J Gruber	1fbfd96f50	detect-compiler: make detection independent of locale `detect-compiler` has accumulated a few compiler dependent workarounds lately for the more and more ubiquitious gcc12. This is intended to make CI set-ups work across tool-chain updates, but also help those developers who build with `DEVELOPER=1`. Alas, `detect-compiler` uses the locale dependent output of `$(CC) -v` to parse for the version string, which fails unless it literally contains ` version`. Use `LANG=C $(CC) -v` instead to grep for stable output. Signed-off-by: Michael J Gruber <git@grubix.eu> Signed-off-by: Junio C Hamano <gitster@pobox.com>	3 years ago
Junio C Hamano	f32c5d3716	build: catch clang that identifies itself as "$VENDOR clang" The case statement in detect-compiler notices 'clang', 'FreeBSD clang' and 'Apple clang', but there are other platforms that follow the '$VENDOR clang' pattern (e.g. Debian). Generalize the pattern to catch them. Signed-off-by: Junio C Hamano <gitster@pobox.com>	4 years ago
Jeff King	33f13ad7c5	build: clang version may not be followed by extra words The get_family and get_version helpers of detect-compiler assume that the line to identify the version from the compilers have a token "version", followed by the version number, followed by some other string, e.g. $ CC=gcc get_version_line gcc version 10.2.1 20210110 (Debian 10.2.1-6) But that is not necessarily true, e.g. $ CC=clang get_version_line Debian clang version 11.0.1-2 Tweak the script not to require extra string after the version.

Carlo Marcelo Arenas Belón	f6bb2099bf	build: update detect-compiler for newer Xcode version `1da1580e4c` (Makefile: detect compiler and enable more warnings in DEVELOPER=1, 2018-04-14) uses the output of the compiler banner to detect the compiler family. Apple had since changed the wording used to refer to its compiler as clang instead of LLVM as shown by: $ cc --version Apple clang version 12.0.5 (clang-1205.0.22.9) Target: x86_64-apple-darwin20.6.0 Thread model: posix InstalledDir: /Library/Developer/CommandLineTools/usr/bin so update the script to match, and allow DEVELOPER=1 to work as expected again in macOS.

Nguyễn Thái Ngọc Duy	1da1580e4c	Makefile: detect compiler and enable more warnings in DEVELOPER=1 The set of extra warnings we enable when DEVELOPER has to be conservative because we can't assume any compiler version the developer may use. Detect the compiler version so we know when it's safe to enable -Wextra and maybe more. These warning settings are mostly from my custom config.mak a long time ago when I tried to enable as many warnings as possible that can still build without showing warnings. Some of those warnings are probably worth fixing instead of just suppressing in future.
