Subject: BUG: $ORIGIN does not seem to work
Hello
On glibc the following:
gcc -o x -Wl,-rpath='$ORIGIN/lib' x.c -L ./lib -lcrypto
or
gcc -o x -Wl,-rpath,'$ORIGIN/lib' x.c -L ./lib -lcrypto
Gives me binary with relative library path
ldd x
linux-vdso.so.1 (0x00007ffcb6bee000)
* libcrypto.so.1.0.0 => /home/wizard/kal-el/lib/libcrypto.so.1.0.0
(0x00007f0bc3593000)**
* libc.so.6 => /lib64/libc.so.6 (0x00007f0bc31e2000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f0bc2fde000)
libz.so.1 => /lib64/libz.so.1 (0x00007f0bc2dc7000)
/lib64/ld-linux-x86-64.so.2 (0x00007f0bc39d2000)
cp -rap kal-el/* batman/
ldd x
linux-vdso.so.1 (0x00007ffdbf0b6000)
* libcrypto.so.1.0.0 => /home/wizard/batman/lib/libcrypto.so.1.0.0
(0x00007fb682149000)**
* libc.so.6 => /lib64/libc.so.6 (0x00007fb681d98000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007fb681b94000)
libz.so.1 => /lib64/libz.so.1 (0x00007fb68197d000)
/lib64/ld-linux-x86-64.so.2 (0x00007fb682588000)
But trying the same with musl does not seem to work?
ldd x
/lib/ld-musl-x86_64.so.1 (0x7f07372e2000)
libc.so => /lib/ld-musl-x86_64.so.1 (0x7f07372e2000)
and if i remove the -L ./lib from the command it uses system library
gcc -o x -Wl,-rpath,'$ORIGIN/lib' x.c -lcrypto
ldd xx
/lib/ld-musl-x86_64.so.1 (0x7fdd8618d000)
libcrypto.so.1.1 => /usr/lib/libcrypto.so.1.1 (0x7fdd85ed7000)
libc.so => /lib/ld-musl-x86_64.so.1 (0x7fdd8618d000)
