bash variable names may only contain alphanumeric ASCII-symbols and _,
and must not start with a number. Nix expression attribute names however
might contain nearly every character (in particular spaces and dashes).
Previously, a substitution that was not a valid bash name would be
expanded to an empty string. This commit introduce a check that throws
a (hopefully) helpful error when a wrong name is used in a substitution.
For every *.{exe,dll} in $output/bin/ we try to find all (potential)
transitive dependencies and symlink those DLLs into $output/bin
so they are found on invocation.
(DLLs are first searched in the directory of the running exe file.)
The links are relative, so relocating whole /nix/store won't break them.
The hook is activated on cygwin and when cross-compiling to mingw.
Close#14335.
Since 89036ef76a, when a package doesn't include a configure script,
the build complains with:
grep: : No such file or directory
grep: : No such file or directory
This prevents that.
Commit 2040a9ac57 changed the order of
$PATH elements, causing initialpath to appear after buildInputs. Thus
gnugrep ended up depending on bin/sh from bootstrapTools, rather than
from pkgs.bash. The fix is to provide pkgs.bash via buildInputs rather
than initialPath.

For some reason, the current bootstrap tools fail to build gettext:

make[5]: *** [libxml/libxml_rpl_la-xpath.lo] Error 1
I didn't investigate why this is the case but rebuilding the bootstrap
tools seems to help.
I used this old-ish WIP branch https://github.com/dezgeg/nixpkgs/commits/arm-bootstrap
since latest master has even more problems with cross-compiling anything.
(I will eventually push this stuff and make the ARM bootstraps build on hydra.)
The $lib output refers to the terminfo database in $out, which is about
10x larger than the ncurses shared library. Splitting these outputs
saves a small amount of space for any derivations that use the terminfo
database but not the ncurses library, but we do not have evidence that
any such exist.
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.
I assume there's not much use for it during bootstrapping.
This fixes them as well, as curl was compiled against libnghttp2 but the
lib wasn't copied to the bootstrap tools.
Fixes#12632.
I think it's better to quote this variable in general, because it is
common and even documented to pass space-separated commands in there.
The greps should just fail in that case and `if` won't proceed
which seems fine for such cases, and it's certainly better than
passing additional unintended parameters to grep
(which was happening all the time before).
Doing it in an openssl setup hook only works if packages have openssl
as a build input - it doesn't work if they're using a program linked
against openssl.
Commit 6d928ab684 changed this to not
preserve timestamps. However, that results in non-determinism; in
particular, it gives us a broken $SOURCE_DATE_EPOCH (especially for
everything using fetchFromGitHub). Builds affected by timestamps <
1980 should be fixed in some other way (e.g. changing the timestamp to
some fixed date > 1980).
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
This is used by some build tools to provide reproducible builds. See
https://reproducible-builds.org/specs/source-date-epoch/
for more info.
Later, we'll want to set this to a more intelligent value (such as the
most recent mtime of any source file).
So far if no configure script is found or no makefile,
the rest of the phase is skipped, *including* post-hooks.
I find that behavior unexpected/unintuitive.
Earlier version of this patch had problems due to me assuming
that $configureScript is always a simple path, but that turned out
to be false in many cases, e.g. perl.
This un-hardcodes the bootstrap tools passed into the Darwin stdenv and
thus allows us to quickly iterate on improving the design of the full
bootstrap process. We can easily change the contents of the bootstrap
tools and evaluate an entire bootstrap all the way up to real packages.
The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.
