--- Comment #2 from Kyle Evans <kev...@freebsd.org> ---
CC'ing re@, because I think this is technically their territory being in
release/, and CC'ing bugs@ to keep it on a list.
Here's a summary of the bugs I've encountered in picobsd so far, and I still
haven't gotten anything usable:
- Script unconditionally sets WITHOUT_CLANG/WITHOUT_CLANG_BOOTSTRAP [0] without
dealing with GCC_BOOTSTRAP. The libllvm build fails because WITHOUT_CLANG shuts
off all of the LLVM_TARGET_* -- build failure.
- Fixing that, native builds cannot work. The script does `set -e`, then [1] --
on a native build, ${o_arch} == `uname -m` and we don't descend down && path,
leaving the function with an erroneous exit code and the script bails out.
- Fixing that, native amd64 builds cannot work. None of these [2] are valid CPU
types for amd64 -- only i386. One can supply their own kernconf, so let's
ignore this for now.
What does work?
- Cross-builds -- kind of, for very primitive cases. [3] sets TARGET_ARCH and
ARCH to whatever was passed in via --arch. This assumes ARCH=TARGET_ARCH, which
rules out, e.g., arm.armv7, most mips flavors, most powerpc flavors, riscv,
arm64
- The i386 build probably does, but I had to fix the ${CONF}/${CONFFILE} target
in Makefile.conf to wrap [ -f ... ] && cpp in () || true in order to
continue... around here I ran out of patience to tolerate further failures for
the night, so I left the build running and detached for the night.
I think re@ should consider dropping this before 13.0, because:
1.) It has no active maintainer and has a lot of deferred maintenance that
needs handled (see: pretty broken by default, and it's been this way for a
while),
2.) It can't handle cross-builds,
3.) I think it fills a niche that's better fit for nanobsd or mfsbsd, which see
more active maintenance
