Subject: Newbie problem with musl-gcc

Hello

I got everything setup on ubuntu 21.04 and it's compiling and linking my 
small statically linked test executable, but I can't run it.

    $ ldd ./foo
         statically linked
    $ ls -l foo
    -rwxrwxr-x 1 nat develop 77224 Okt  8 02:05 foo
    $ sudo strace ./foo
    execve("./foo", ["./foo"], 0x7ffe245a03c0 /* 26 vars */) = -1 ENOENT
    (Datei oder Verzeichnis nicht gefunden)
    strace: exec: Datei oder Verzeichnis nicht gefunden
    +++ exited with 1 +++


I assume this is a common newbie problem, but in case not:

    Linux localhost 5.11.0-37-generic #41-Ubuntu SMP Mon Sep 20 16:39:20
    UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
    gcc (Ubuntu 10.3.0-1ubuntu1) 10.3.0
    musl is not installed


How I built musl-1.2.2 (this is basically non-negotiable, if I can't 
have it build "static only" outside of root, this is no use for me)

    CC='cc' CFLAGS='-g -O0' CXXFLAGS='-g -O0' ./configure 
    --disable-shared --prefix='/tmp/dependency'
    make  VERBOSE=1 -j 64 all
    make VERBOSE=1 -j 64 install


How I built "foo.c":

    cat <<EOF > foo.c
    #include <stdio.h>

    int  main( void)
    {
        printf( "VfL Bochum 1848\n");
        return( 0);
    }
    EOF

    PATH="/tmp/dependency/bin:$PATH"

    musl-gcc -o foo foo.c

Thanks for any help in advance
     Nat!
