Bug ID: 106271
Summary: Bootstrap on RISC-V on Ubuntu 22.04 LTS:
bits/libc-header-start.h: No such file or directory
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: tkoenig at gcc dot gnu.org
Target Milestone: ---
I thought I would give the new gcc92 machine a spin and tried
bootstrapping gcc on it.
Configure was done with
../Gcc/configure --disable-multilib --prefix=$HOME
--enable-languages=c,c++,fortran
and the last few lines of output were
/home/tkoenig/trunk-bin/./gcc/xgcc -B/home/tkoenig/trunk-bin/./gcc/

I suspect configure is not detecting multi-arch correctly or --disable-multilib
interacting with multi-arch support which causes things to be broken.
OR multi-arch support is not in the riscv backend yet.

I get the same result without --disable-multilib.

--- Comment #3 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
Gah, I ran into the same issue on gcc92.
I 'configure'd '--with-arch=rv64imafdc --with-abi=lp64d --enable-multilib'.
(In reply to Andrew Pinski from comment #1)
> OR multi-arch support is not in the riscv backend yet.
That seems to be the case indeed; at least I'm not seeing any 'if_multiarch'
etc. in 'gcc/config/riscv/'.
$ find /usr/include/ -name libc-header-start.h
/usr/include/riscv64-linux-gnu/bits/libc-header-start.h
Also, do potentially further distribution packages have to be installed, for
additional multilibs? Like I have on an Ubuntu x86_64 GN/Linux system:
$ find /usr/include/ -name libc-header-start.h
/usr/include/i386-linux-gnu/bits/libc-header-start.h
/usr/include/x86_64-linux-gnu/bits/libc-header-start.h
$ dpkg -S /usr/include/i386-linux-gnu/bits/libc-header-start.h
/usr/include/x86_64-linux-gnu/bits/libc-header-start.h
libc6-dev:i386: /usr/include/i386-linux-gnu/bits/libc-header-start.h
libc6-dev:amd64: /usr/include/x86_64-linux-gnu/bits/libc-header-start.h

..., and then I wondered: but how, then, are Debian/Ubuntu building GCC?
Per <https://packages.debian.org/experimental/gcc-13>,
<http://deb.debian.org/debian/pool/main/g/gcc-13/gcc-13_13.1.0-3.debian.tar.xz>,
there is a 'debian/patches/gcc-multiarch.diff' file, which contains "Remaining
multiarch patches, not yet submitted upstream", which (amongst others)
includes:

--- Comment #5 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
With the latter hunk applied (plus manual 'rm gcc/s-mlib gcc/multilib.h' to
regenerate the latter file), I find that this apparently does only address the
'--disable-multilib' case, but not my '--enable-multilib'?

I noticed recent commit r14-3387-g47f95bc4be4eb14730ab3eaaaf8f6e71fda47690
"RISC-V: Add multiarch support on riscv-linux-gnu" -- but can't tell off-hand
whether that fixed all the issues here?

As soon as gcc92 is back up, we can test...

I wasn't aware of this BZ when I made the commit referenced in c#6. But yes,
the whole point of that commit was to fix this problem.

yes, that's one which could be also backported. Let me submit the other bits
upstream as well.
