|/ | | | | | | I hate the thing too even though I made it, and rather just get rid of it. But we can't do that yet. In the meantime, this brings us more inline with autoconf and will make it slightly easier for me to write a pkg-config wrapper, which we need.

| * | stdenv: Introduce hasCC attributeJohn Ericson2019-11-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before, we'd always use `cc = null`, and check for that. The problem is this breaks for cross compilation to platforms that don't support a C compiler. It's a very subtle issue. One might think there is no problem because we have `stdenvNoCC`, and presumably one would only build derivations that use that. The problem is that one still wants to use tools at build-time that are themselves built with a C compiler, and those are gotten via "splicing". The runtime version of those deps will explode, but the build time / `buildPackages` versions of those deps will be fine, and splicing attempts to work this by using `builtins.tryEval` to filter out any broken "higher priority" packages (runtime is the default and highest priority) so that both `foo` and `foo.nativeDrv` works. However, `tryEval` only catches certain evaluation failures (e.g. exceptions), and not arbitrary failures (such as `cc.attr` when `cc` is null). This means `tryEval` fails to let us use our build time deps, and everything comes apart. The right solution is, as usually, to get rid of splicing. Or, baring that, to make it so `foo` never works and one has to explicitly do `foo.*`. But that is a much larger change, and certaily one unsuitable to be backported to stable. Given that, we instead make an exception-throwing `cc` attribute, and create a `hasCC` attribute for those derivations which wish to condtionally use a C compiler: instead of doing `stdenv.cc or null == null` or something similar, one does `stdenv.hasCC`. This allows quering without "tripping" the exception, while also allowing `tryEval` to work. No platform without a C compiler is yet wired up by default. That will be done in a following commit.

| | | | | | | | | | | | | | | | | | | | | | | | If an empty string is passed to `-idirafter`, it breaks gcc. This commit makes the stdenv less fragile by expanding out the shell glob and ensuring no empty arguments get passed.

* cc-wrapper: use -iframework instead of -FMatthew Bauer2019-06-28
| | | | | | | | This avoids dumping -Wall warnings when they appear in framework headers. As a result, we are closer to how regular headers are included (via -isystem). Also remove ccIncludeFlag lookup, this was unused & not very useful.
* cc-wrapper: only set -march when platform.gcc.arch is specifiedMatthew Bauer2019-04-26
| | | | | | | | | | We want to make sure this value is explicitly set. Infering it for every arch leads to annoying failures like: https://hydra.nixos.org/build/92583832/ Perhaps we can enable it in the future with some smarter handling of cc-wrapper.sh.

* | cc-wrapper: make machine configuration configurableMatthew Bauer2019-04-20
|/ | | | | | | | | | | | | | | | | | | | | | It is useful to make these dynamic and not bake them into gcc. This means we don’t have to rebuild gcc to change these values. Instead, we will pass cflags to gcc based on platform values. This was already done hackily for android gcc (which is multi-target), but not for our own gccs which are single target. To accomplish this, we need to add a few things: - add ‘arch’ to cpu - add NIX_CFLAGS_COMPILE_BEFORE flag (goes before args) - set -march everywhere - set mcpu, mfpu, mmode, and mtune based on targetPlatform.gcc flags cc-wrapper: only set -march when it is in the cpu type Some architectures don’t have a good mapping of -march. For instance POWER architecture doesn’t support the -march flag at all! https://gcc.gnu.org/onlinedocs/gcc/RS_002f6000-and-PowerPC-Options.html#RS_002f6000-and-PowerPC-Options
* llvm8: support c++ in cross caseMatthew Bauer2019-04-11
| | | | | | | | | | this adds libc++ to the LLVM cross, giving us access to the full Nixpkgs set. This requires 4 stages of wrapped compilers: - Clang with no libraries - Clang with just compiler-rt - Clang with Libc, and compiler-rt - Clang with Libc++, Libc, and compiler-rt

|/ | | | | | | | | | | clang needs to find headers + libraries for compiling with libc++. We need to add a libcxx argument to cc-wrapper. This means you do not have to pass in c++ headers directly. This resolves the last case remaining of #30670. Darwin clang++ now works properly. Fixes #30670

|\ | | | | cc-wrapper, bintools-wrapper: simply symlink man and info outputs
| * cc-wrapper, bintools-wrapper: simply symlink man and info outputsJan Malakhovski2018-11-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the previous commit `propagateDoc` is now always given the correct value (i.e. it is never set to `true` when there are no `man` and `info` outputs). Hence, we can simply symlink the original outputs to the wrapper outputs. Pros: - simpler, less indirection compared to `propagated-user-env-packages`, - uses less inodes (1 symlink, which nix then simply automatically resolves and removes, vs. two directories and a file), - makes direct references like "export MANPATH=${stdenv.cc.man}/share/man" simply work. Cons: - I'm not aware of any. This and the previous commit together almost completely revert commits fde7296a4749efadbeb8b608b7b4cc01c3a6e6d7, fa412972091538376d1d4ffd446803b5d9385cbb, and c981787db951afb11c1328461df82d4277ebec07.

|/ | | | | | | | | | | | | | | | | | - respect libc’s incdir and libdir - make non-unix systems single threaded - set LIMITS_H_TEST to false for avr - misc updates to support new libc’s - use multilib with avr For threads we want to use: - posix on unix systems - win32 on windows - single on everything else For avr: - add library directories for avrlibc - to disable relro and bind - avr5 should have precedence over avr3 - otherwise gcc uses the wrong one
* bintools-wrapper, cc-wrapper, stdenv: infer propagateDoc automaticallyJan Malakhovski2018-09-23
| | | | | | | | | | | | | | 02c09e01712ce0b61e5c8f7159047699a434f7fc (NixOS/nixpkgs#44558) was reverted in c981787db951afb11c1328461df82d4277ebec07 but, as it turns out, it fixed an issue I didn't know about at the time: the values of `propagateDoc` options were (and now again are) inconsistent with the underlying things those wrappers wrap (see NixOS/nixpkgs#46119), which was (and now is) likely to produce more instances of NixOS/nixpkgs#43547, if not now, then eventually as stdenv changes. This patch (which is a simplified version of the original reverted patch) is the simplest solution to this whole thing: it forces wrappers to directly inspect the outputs of the things they are wrapping instead of making stdenv guess the correct values.
