in repository guix.
commit a795a02a9d988be5a762886620f7bb6a95e7ffdb
Author: Christopher Baines <mail@cbaines.net>
AuthorDate: Sat May 6 14:16:17 2023 +0100
gnu: Use gexps for gcc-boot0 and related packages.
There are currently problems with native or cross building for i586-gnu, and
one factor mixed up with this is that some of the gcc packages use sexp's
for
the phases, and thus introducing gexp's has caused problems.
As part of the going in circles with this, this commit switches gcc-boot0 to
use gexp's in it's arguments, and then also modifies libstdc++-boot0,
libstdc++-boot0-gcc7, cross-gcc-wrapper, gcc-final and make-libstdc++ to
handle this change.
If done correctly, this change shouldn't affect any derivations.
* gnu/packages/commencement.scm (libstdc++-boot0, libstdc++-boot0-gcc7,
gcc-boot0, gcc-final)[arguments]: Use gexps.
(cross-gcc-wrapper): Use gexps in the generated package.
* gnu/packages/gcc.scm (make-libstdc++): Use gexps in the generated package.
