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!

I think I have seen this before. ldd sometimes returns the wrong info.
Try "readelf -l" on the program to verify it has no interpreter. I have
reason to believe that it does have musl's interpreter, and you have not
properly installed musl.

Was this really just an elaborate attempt to advertise your favourite
football club? Just kidding.

This doesn't say -static in there. Try adding that and see was happens.
musl-gcc essentially just adds a different specs file to GCC, and that
file is not changed based on the choice to have the shared library or
not.
Ciao,
Markus

Nice, now it works.

But why not ? It would make sense, wouldn't it ?
Thanks for the help.
Ciao

I believe the desired default, even with musl, is to use dynamic libraries.
So, IMO, the current behavior is expected and desired.
