2019-07-03 autoconf: Allow overriding CFLAGS/CXXFLAGS from outside.Niklas Hambüchen1-2/+4
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
2019-07-03 autoconf: Fix AC_STRUCT_DIRENT_D_TYPE being used before AC_PROG_CC.Niklas Hambüchen1-8/+8
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 `: ${CFLAGS=""}` will be used, so it's important to get this working first.)
2019-07-03 autoconf: Fix C++17 detection not working on Ubuntu 16.04.Niklas Hambüchen1-1/+2
And probably many other distributions. Until now, ./configure would fail silently printing a warning ./configure: line 4621: AX_CXX_COMPILE_STDCXX_17: command not found and then continuing, later failing with a C++ #error saying that some C++11 feature isn't supported (it didn't even get to the C++17 features). This is because older distributions don't come with the `AX_CXX_COMPILE_STDCXX_17` m4 macro. This commit vendors that macro accordingly. Now ./configure complains correctly: configure: error: *** A compiler with support for C++17 language features is required. On Ubuntu 16.04, ./configure completes if a newer compiler is used, e.g. with gcc-7 from https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/test using: ./bootstrap.sh ./configure CXX=g++-7 --disable-doc-gen --with-boost=$(nix-build --no-link '<nixpkgs>' -A boost.dev)
2019-07-03 autoconf: Work around editline not being found on Ubuntu 16.04.Niklas Hambüchen1-1/+10
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.
2019-07-03 autoconf: Detect boost, require version, set CXXFLAGS.Niklas Hambüchen1-0/+7
This turns previous compiler errors complaining about missing files into proper ./configure time errors telling the user which version of boost is required.
2019-07-03 autoconf: Change quotes in description.Niklas Hambüchen1-1/+1
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.
2019-03-25 configure.ac: update for new version file locationWill Dietz1-1/+1
2019-03-10 require c++ 17Guillaume Maudoux1-1/+1
This fixes warnings about "structured binding declaration" requiring "-std=c++1z".
2019-02-13 Support --disable-shared flag.Matthew Bauer1-0/+10
This tells Nix to not build the shared libraries.
2019-01-10 Revert "Remove some bashisms from configure.ac"Eelco Dolstra1-11/+6
This reverts commit e8b0efdcc9d6329b299937790360cac8b9b256c9.
2019-01-10 Revert "Escape square brackets in configure.ac"Eelco Dolstra1-1/+1
This reverts commit 80f464d9d72839841422f75e78ce725365cc3d71.
2019-01-09 Escape square brackets in configure.acMateusz Piotrowski1-1/+1
This patch attempts to solve the regression introduced in e8b0efdc (#2607).
2019-01-07 Merge pull request #2607 from 0mp/configure.ac-fixEelco Dolstra1-6/+11
Remove some bashisms from configure.ac
2019-01-07 Don't look for a "pv" program, or mention it in the manual sourceJohn Ericson1-1/+0
The manual reference was commented out, and the sole reference to this program other than the configure script. Removed both.
2019-01-05 brotli is only used as a library nowJohn Ericson1-1/+0
2019-01-05 Remove dead code computing `dynlib_suffix` from comfigure.acJohn Ericson1-5/+0
2018-12-30 Remove some bashisms from configure.acMateusz Piotrowski1-6/+11
"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.
2018-10-29 editline: wipWill Dietz1-0/+2
2018-09-03 docs: change expired bzip2.org to archive.orgVladimír Čunát1-2/+2
Fixes #2396.
2018-08-20 Drop all references to --disable-init-stateTuomas Tynkkynen1-6/+0
It's all dead code since 2014 (commit 0c6d62cf27b3b2).

2018-04-06 Use $CPPFLAGS when detecting version of aws-sdk-cppAndrew Dunham1-1/+1

2018-02-19 configure.ac: define HAVE_SECCOMP macro when using seccomp, fix build/testsWill Dietz1-0/+1
Happily the failing tests should prevent anyone from using such a Nix in situations where they expect sandboxing to be on, which would otherwise be a risk.
2018-02-19 Merge pull request #1857 from dtzWill/fix/check-for-lzma-mtEelco Dolstra1-0/+2
configure.ac: check if lzma has MT support, fix deb build/etc.
2018-02-18 configure: Add a flag to disable seccomp.Shea Levy1-2/+14
This is needed for new arches where libseccomp support doesn't exist yet. Fixes #1878.
2018-02-09 configure.ac: check if lzma has MT support, fix deb build/etc.Will Dietz1-0/+2
2018-01-29 configure: Use $CPP instead of cpp directlyBen Gamari1-1/+2
The latter breaks in the case of cross-compilation, when `cpp` bears a target prefix.
2017-12-30 use libbrotli directly when availableWill Dietz1-1/+8
* Look for both 'brotli' and 'bro' as external command, since upstream has renamed it in newer versions. If neither are found, current runtime behavior is preserved: try to find 'bro' on PATH. * Limit amount handed to BrotliEncoderCompressStream to ensure interrupts are processed in a timely manner. Testing shows negligible performance impact. (Other compression sinks don't seem to require this)
2017-12-22 Check aws-sdk-cpp versionEelco Dolstra1-1/+7
2017-05-29 Add a seccomp filter to prevent creating setuid/setgid binariesEelco Dolstra1-0/+7
This prevents builders from setting the S_ISUID or S_ISGID bits, preventing users from using a nixbld* user to create a setuid/setgid binary to interfere with subsequent builds under the same nixbld* uid. This is based on aszlig's seccomp code (47f587700d646f5b03a42f2fa57c28875a31efbe). Reported by Linus Heckemann.
2017-05-15 Add --with-sandbox-shell configure flagEelco Dolstra1-0/+6
And add a 116 KiB ash shell from busybox to the release build. This helps to make sandbox builds work out of the box on non-NixOS systems and with diverted stores.
2017-05-10 Replace readline by linenoiseEelco Dolstra1-8/+0
Using linenoise avoids a license compatibility issue (#1356), is a lot smaller and doesn't pull in ncurses.
2017-04-28 Check for libreadlineEelco Dolstra1-0/+8
2017-04-20 Detect lsofEelco Dolstra1-0/+1
Also, don't use lsof on Linux since it's not needed. Fixes #1328.

2017-03-21 Don't make brotli a hard dependencyEelco Dolstra1-1/+1
2017-03-15 Add support for brotli compressionEelco Dolstra1-0/+1
Build logs on cache.nixos.org are compressed using Brotli (since this allows them to be decompressed automatically by Chrome and Firefox), so it's handy if "nix log" can decompress them.
2017-03-15 Remove dependency on "curl" binaryEelco Dolstra1-1/+0

2017-02-21 Revert "configure.ac: We require C++14 now"Eelco Dolstra1-1/+1
This reverts commit 81c53fe8e56f4a4ce10088fe2d7b6a524a6dc126. This check appears to be stricter than we need (it broke a bunch of platforms that previously did build: http://hydra.nixos.org/eval/1331921#tabs-now-fail).
2017-02-08 configure.ac: We require C++14 nowTuomas Tynkkynen1-1/+1
At least in the main Makefile we have: GLOBAL_CXXFLAGS += -std=c++14 -g -Wall
2017-02-07 Remove perl dependency.Shea Levy1-52/+0
Fixes #341
2016-12-19 Revert "Merge branch 'seccomp' of https://github.com/aszlig/nix"Eelco Dolstra1-9/+0
This reverts commit 9f3f2e21edb17dbcd674539dff96efb6cceca10c, reversing changes made to 47f587700d646f5b03a42f2fa57c28875a31efbe.

2016-11-16 Add build dependency for libseccompaszlig1-0/+9
We're going to use libseccomp instead of creating the raw BPF program, because we have different syscall numbers on different architectures. Although our initial seccomp rules will be quite small it really doesn't make sense to generate the raw BPF program because we need to duplicate it and/or make branches on every single architecture we want to suuport.
