Nikolay Amiantov 87607af7a1 cc-wrapper: add C++-specific paths if -x c++ is passed 2016-03-14 06:58:18 +03:00
Robin Gloster a9b942c061 cc-wrapper: treat hardeningDisable as string
This fixes passing the env variable to the ld-wrapper through the gcc
call. Wtf?!

Vladimír Čunát 09af15654f Merge master into closure-size
The kde-5 stuff still didn't merge well.
I hand-fixed what I saw, but there may be more problems.

Franz Pletz aff1f4ab94 Use general hardening flag toggle lists
The following parameters are now available:

  * hardeningDisable
    To disable specific hardening flags
  * hardeningEnable
    To enable specific hardening flags

Only the cc-wrapper supports this right now, but these may be reused by
other wrappers, builders or setup hooks.

cc-wrapper supports the following flags:

  * fortify
  * stackprotector
  * pie (disabled by default)
  * pic
  * strictoverflow
  * format
  * relro
  * bindnow

Eelco Dolstra d5bb6a1f9c glibc: Enable separate debug symbols
The importance of glibc makes it worthwhile to provide debug
symbols. However, this revealed an issue with separateDebugInfo: it
was indiscriminately adding --build-id to all ld invocations, while in
fact it should only do that for final links. Glibc also uses non-final
("relocatable") links, leading to subsequent failure to apply a build
ID ("Cannot create .note.gnu.build-id section, --build-id
ignored"). So now ld-wrapper.sh only passes --build-id for final
links.

Eelco Dolstra 2040a9ac57 stdenv-linux: Ensure binutils comes before bootstrapTools in $PATH
Otherwise, when building glibc and other packages, the "strip" from
bootstrapTools is used, which doesn't recognise some tags produced by
the newer "ld" from binutils.

Vladimír Čunát 96cbdc70f2 cc-wrapper: fix #10574: old gcc -> cc fallout
The part with gcc-wrapper-old changes is rather unimportant,
as it's almost unused but I still tested that the sole user `gnat` builds.

Vladimír Čunát a33fcc8731 cc-wrapper: attempt to fix on darwin
This fixes evaluation at least. I'm unable to test this myself and noone steps up;
https://github.com/NixOS/nixpkgs/pull/7701#issuecomment-174448705
however, Hydra's macs are idling so let's employ them for that.

Vladimír Čunát 8f48a9756b cc-wrapper: quote when saving $PATH 2016-01-25 09:54:10 +01:00
Anthony Cowley d96893647d cc-wrapper: fix on darwin
The ld-wrapper.sh script calls `readlink` in some circumstances. We need
to ensure that this is the `readlink` from the `coreutils` package so
that flag support is as expected.

This is accomplished by explicitly setting PATH at the top of each shell
script.

Without doing this, the following happens with a trivial `main.c`:

```
nix-env -f "<nixpkgs>" -iA pkgs.clang
$ clang main.c -L /nix/../nix/store/2ankvagznq062x1gifpxwkk7fp3xwy63-xnu-2422.115.4/Library -o a.out
readlink: illegal option -- f
usage: readlink [-n] [file ...]
```

The key element is the `..` in the path supplied to the linker via a
`-L` flag. With this patch, the above invocation works correctly on
darwin, whose native `/usr/bin/readlink` does not support the `-f` flag.

The explicit path also ensures that the `grep` called by `cc-wrapper.sh`
is the one from Nix.

Fixes #6447

Vladimír Čunát efcad4c910 gcc5: split $doc into $man and $info
... because cc-wrapper is meant to propagate man pages into user envs,
and info pages are rather large.

Also replace the duplicate g++ and gcc man1 pages by a symlink.

Vladimír Čunát 55d129609d cc-wrapper: correct ccLDFlags with multiple outputs
Note: -B argument seems more like for gcc's main output,
though it's used in a bit strange way here.
(Upstream default is /usr/lib/gcc/ which we don't move.)

Eelco Dolstra 6671bb8be4 Remove gccStdInc
This reverts d927da8dae. Having a copy
of gcc-wrapper/setup-hook.sh is bad for maintainability - it had
already started to diverge. Also, gccStdInc gave a nix-env conflict
with the standard gcc. And it wasn't actually used in Nixpkgs.

Instead, if you really need to change "-isystem" to "-I", you can now
set ccIncludeFlag to "-I".

Vladimír Čunát d484c392aa stdenv multiple-outputs: change propagation rules
Now development stuff is propagated from the first output,
and userEnvPkgs from the one with binaries.

Also don't move *.la files (yet). It causes problems, and they're small.

Vladimír Čunát bf414c9d4f Merge 'staging' into closure-size
- there were many easy merge conflicts
- cc-wrapper needed nontrivial changes

Many other problems might've been created by interaction of the branches,
but stdenv and a few other packages build fine now.

Shea Levy f91dea4c0b cc-wrapper: Set default system include flags for non-gcc c++ on Linux
Without this, clang can't find libstdc++. This needs to happen in the wrapper
