This reverts commit ab6c8643d4. Issue
https://github.com/NixOS/nix/issues/609 has been resolved, the new Nix
version is available after 86eaeb4c0a, and
using nix-collect-garbage has the advantage that the '-d' flag is
available, which nix-store doesn't have.
* Compile with gcc5 to avoid the compiler bug described in
https://gcc.gnu.org/ml/gcc-patches/2014-05/msg02560.html
* Add a patch to fix the many incorrect printf format specifiers and
other sloppy type conversions that gcc5 catches and warns on
(erroring out due to -Werror).
In 4.1, the build system changed, and it now wants to execute ld like this:
ld -r -o util/scripting-engines/libperf-in.o util/scripting-engines/trace-event-perl.o util/scripting-engines/trace-event-python.o
The actual problem seems to be that `buildInputs = [elfutils ...]`
causes 'ld' to point to elfutils in PATH instead of the usual binutils.
So remove elfutils from buildInputs and set NIX_CFLAGS_* manually. This
is a slight hack, but there is some precedent:
0761f81da7/pkgs/tools/package-management/rpm/default.nix (L13)Fixes#9095.
Or else users may see this unfriendly message:
error: cannot coerce null to a string, at .../nixos/modules/services/x11/display-managers/gdm.nix:107:49
Second attempt to resolve this issue. Copies stage1 image into expected
place manually. This has been improved in rkt master where there is a
configure option for specifying the location of this file. Can update
when next stable rkt is released.
Local build and run successful.
