2021-02-22Add x86_64 compute levels as additional system typesDaniël de Kok
When performing distributed builds of machine learning packages, it would be nice if builders without the required SIMD instructions can be excluded as build nodes. Since x86_64 has accumulated a large number of different instruction set extensions, listing all possible extensions would be unwieldy. AMD, Intel, Red Hat, and SUSE have recently defined four different microarchitecture levels that are now part of the x86-64 psABI supplement and will be used in glibc 2.33: https://gitlab.com/x86-psABIs/x86-64-ABI https://lwn.net/Articles/844831/ This change uses libcpuid to detect CPU features and then uses them to add the supported x86_64 levels to the additional system types. For example on a Ryzen 3700X: $ ~/aps/bin/nix -vv --version | grep "Additional system" Additional system types: i686-linux, x86_64-v1-linux, x86_64-v2-linux, x86_64-v3-linux

Per the comments, the underlying issue is https://github.com/libarchive/libarchive/issues/1446, knowing this allows the hack to be much more targetted.

2019-07-03Get BOOST_LDFLAGS from autoconf, fix Ubuntu 16.04 build.Niklas Hambüchen
Our use of boost::coroutine2 depends on -lboost_context, which in turn depends on `-lboost_thread`, which in turn depends on `-lboost_system`. I suspect that this builds on nix only because of low-level hacks like NIX_LDFLAGS. This commit passes the proper linker flags, thus fixing bootstrap builds on non-nix distributions like Ubuntu 16.04. With these changes, I can build Nix on Ubuntu 16.04 using: ./bootstrap.sh ./configure --prefix=$HOME/editline-prefix \ --disable-doc-gen \ CXX=g++-7 \ --with-boost=$HOME/boost-prefix \ EDITLINE_CFLAGS=-I$HOME/editline-prefix/include \ EDITLINE_LIBS=-leditline \ LDFLAGS=-L$HOME/editline-prefix/lib make where * g++-7 comes from gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test, * editline 1.14 from https://github.com/troglobit/editline/releases/tag/1.14.0 was installed into `$HOME/editline-prefix` (because Ubuntu 16.04's `editline` is too old to have the function nix uses), * boost 1.66 from https://www.boost.org/doc/libs/1_66_0/more/getting_started/unix-variants.html was installed into $HOME/boost-prefix (because Ubuntu 16.04 only has 1.58)
2019-07-03autoconf: Allow overriding CFLAGS/CXXFLAGS from outside.Niklas Hambüchen
As is normal for autoconf-based projects. For example, it is a common use case to do ./configure CXXFLAGS=-O0 This did not work for nix until now, because the `CXXFLAGS=` declaration would unconditionally erase what the user had specified. The custom `OPTIMIZE` flag is removed, but the default `-O3` is retained; autoconf would default to `-g -O2` by default otherwise as documented on: https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/C-Compiler.html https://www.gnu.org/software/autoconf/manual/autoconf-2.60/html_node/C_002b_002b-Compiler.html
2019-07-03autoconf: Fix AC_STRUCT_DIRENT_D_TYPE being used before AC_PROG_CC.Niklas Hambüchen
That was incorrect, because checking the dirent type already requires a working compiler. It had the effect that setting e.g. `: ${CFLAGS=""}` before `AC_PROG_CC` as per `AC_PROG_CC`'s documentation would have no effect, because `AC_STRUCT_DIRENT_D_TYPE` would automatically set CFLASGS. (In a followup commit `: ${CFLAGS=""}` will be used, so it's important to get this working first.)
2019-07-03autoconf: Fix C++17 detection not working on Ubuntu 16.04.Niklas Hambüchen
And probably many other distributions. Until now, ./configure would fail silently printing a warning ./configure: line 4621: AX_CXX_COMPILE_STDCXX_17: command not found and then continuing, later failing with a C++ #error saying that some C++11 feature isn't supported (it didn't even get to the C++17 features). This is because older distributions don't come with the `AX_CXX_COMPILE_STDCXX_17` m4 macro. This commit vendors that macro accordingly. Now ./configure complains correctly: configure: error: *** A compiler with support for C++17 language features is required. On Ubuntu 16.04, ./configure completes if a newer compiler is used, e.g. with gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test using: ./bootstrap.sh ./configure CXX=g++-7 --disable-doc-gen --with-boost=$(nix-build --no-link '<nixpkgs>' -A boost.dev)
2019-07-03autoconf: Work around editline not being found on Ubuntu 16.04.Niklas Hambüchen
And probably other Linux distributions with long-term support releases. Also update manual stating what version is needed; I checked that 1.14 is the oldest version with which current nix compiles, and added autoconf feature checks for some functions added in that release that nix uses.
2019-07-03autoconf: Detect boost, require version, set CXXFLAGS.Niklas Hambüchen
This turns previous compiler errors complaining about missing files into proper ./configure time errors telling the user which version of boost is required.
2019-07-03autoconf: Change quotes in description.Niklas Hambüchen
The unbalanced single-quotes cause many editor syntax highlighters to interpret the rest of the file as a string literal, making it easier to make syntax mistakes in absence of proper highlighting.

Remove some bashisms from configure.ac

The manual reference was commented out, and the sole reference to this program other than the configure script. Removed both.

2018-12-30Remove some bashisms from configure.acMateusz Piotrowski
"configure.ac" is used to generate "configure", which is supposed to be run with /bin/sh (as suggested by the shebang line of "configure"). As a result it is a good idea to remove any /bin/sh-incompatible syntax from configure.ac. Otherwise, systems that do not use Bash as their /bin/sh are unable to run "configure" due to syntax errors.
