argp-standalone pass1 builds in a separate build directory. Its testsuite
compiles sources that include <argp.h>, but without an explicit include path
the header in the source root is not found and build fails.
Set:
- CPPFLAGS=-I/Users/luoyanpan/CLionProjects/guix/live-bootstrap/..
in src_configure so testsuite objects can resolve argp.h during the normal
phase.
- add steps-guix/argp-standalone-1.4.1/pass1.sh
- run autoreconf before configure
- build/install with standard flow into /kernel-toolchain
- wire argp-standalone-1.4.1 into steps-guix manifest after gcc
- prepare argp for later kernel-side elfutils dependency
