--- Comment #4 from Sergei Trofimovich ---
Yeah, getting musl toolchain is trickier than glibc's. I suggest using a chroot
(or equivalent) of linux distribution that already supports it. I'm personally
using nixpkgs.
More conventional FHS-style distribution using musl would be adelie. Full
session to reproduce the failure there:
# Get smallest rootfs from https://www.adelielinux.org/download/ (10MB),
# unpack and and enter the chroot:
$ mkdir /tmp/repro && cd /tmp/repro
$ wget
https://distfiles.adelielinux.org/adelie/1.0/iso/rc2/adelie-rootfs-mini-x86_64-1.0-rc2.txz
$ sudo tar xf adelie-rootfs-mini-x86_64-1.0-rc2.txz
$ sudo systemd-nspawn --directory=.
# Install bash (default shell is a bit clunky),
# and build tools, fetch binutils and build it:
$$ /sbin/apk add bash && bash
$$ /sbin/apk add build-tools m4 bison flex gmp-dev texinfo
$$ git clone --depth 1 https://sourceware.org/git/binutils-gdb.git
$$ cd binutils-gdb/
$$ ./configure && make

It's a fully working basic c++ development environment:
$$ printf "#include \nint main() { std::cout << \"yay\" <<

yay
Hope that helps.

It does not try to be fully compatible to GNU libc, but mostly targets POSIX. Thus a few glibc-specific things are missing and some things are in different locations. SIGEV_THREAD_ID is defined in http://git.musl-libc.org/cgit/musl/tree/include/signal.h#n205: include/signal.h:#define SIGEV_THREAD_ID 4 > Also what is an output of `grep -ns pwrite /usr/include/*` on your build > machine ? 'pwrite' is defined in unistd.h http://git.musl-libc.org/cgit/musl/tree/include/unistd.h#n204 But there is a catch: pwrite and pwrite64 are not different symbols and are macro aliases: ssize_t pwrite(int, const void *, size_t, off_t); #if defined(_LARGEFILE64_SOURCE) || defined(_GNU_SOURCE) #define pwrite64 pwrite #endif Also, `dlvsym()` does not exist on musl, and GLIBC-specific symbol versions are not available, thus things like the below don't work: ptr = dlvsym (dlflag, "pthread_mutex_unlock", "GLIBC_2.0"); -- You are receiving this mail because: You are on the CC list for the bug.
