6527682ab7058e5023a2a6dea01d51c15dca701f - src: Use gnu++17 as the default C++ standard

Fri, 11 Apr 2025 15:53:50 +0200

src: Use gnu++17 as the default C++ standardPreviously the compiler's default C++ standard was used unlike C wherebsd.sys.mk explicitly sets a default language version. Setting anexplicit default version will give a more uniform experience acrossdifferent compilers and compiler versions.gnu++17 was chosen to match the default C standard. It is wellsupported by a wide range of clang (5+) and GCC (9+) versions.gnu++17 is also the default C++ standard in recent versions of clang(16+) and GCC (11+). As a result, many of the explicit CXXSTDsettings in Makefiles had the effect of lowering the C++ standardinstead of raising it as was originally intended and are removed.Note that the remaining explicit CXXSTD settings for atf and liblutokexplicitly lower the standard to C++11 due to use of the deprecatedauto_ptr<> template which is removed in later versions.Reviewed by: imp, asomers, dim, emasteDifferential Revision: https://reviews.freebsd.org/D49223 List of files: /freebsd/lib/libcxxrt/Makefile

Fri, 17 May 2024 22:22:22 +0200

libcxxrt: allow build with gcc13 and --no-undefined-versionGCC 13 supports _Float16 and __int128 on fewer architectures than clangand thus libcxxrt compiled with gcc13 is sometimes missing relatedsymbols. Hack around this by explicitly appending --undefined-versionto LDFLAGS in problematic cases.Reviewed by: theraven, dimDifferential Revision: https://reviews.freebsd.org/D45233 List of files: /freebsd/lib/libcxxrt/Makefile

e8067928ff5f819ef78ad4acfb12124415ea2fff - Standardize `-std=c++* as `CXXSTD`

Fri, 29 Mar 2019 19:45:27 +0100

Standardize `-std=c++* as `CXXSTD`CXXSTD was added as the C++ analogue to CSTD.CXXSTD defaults to `-std=c++11` with supporting compilers; `-std=gnu++98`,otherwise for older versions of g++.This change standardizes the CXXSTD variable, originally added togoogletest.test.inc.mk as part of r345203.As part of this effort, convert all `CXXFLAGS+= -std=*` calls to use `CXXSTD`.Notes:This value is not sanity checked in bsd.sys.mk, however, given the twomost used C++ compilers on FreeBSD (clang++ and g++) support both modes, it islikely to work with both toolchains. This method will be refined in the futureto support more variants of C++, as not all versions of clang++ and g++ (forinstance) support C++14, C++17, etc.Any manual appending of `-std=*` to `CXXFLAGS` should be replaced with CXXSTD.Example:Before this commit:```CXXFLAGS+= -std=c++14```After this commit:```CXXSTD= c++14```Reviewed by: asomersApproved by: emaste (mentor)MFC after: 1 monthMFC with: r345203, r345704, r345705Relnotes: yesTested with: make tinderboxDifferential Revision: https://reviews.freebsd.org/D19732 List of files: /freebsd/lib/libcxxrt/Makefile
