support linker files #7
Description
Hi there,
During the build of the archlinux aur/julia-git package I've encountered the following issue:
./libwhich -p libm.so
failed to open library: /usr/lib/libm.so: invalid ELF header
And indeed, I have
file /usr/lib/libm.so
/usr/lib/libm.so: ASCII text
On this site it is claimed, that
.so files are not designed to be loaded, but to be used at link time.
Therefore it's perfectly fine for them to be a linker file.
What is should be the correct behaviour here?
strace -e openat ./libwhich -p libm.so
openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/usr/lib/libdl.so.2", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/usr/lib/libc.so.6", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/etc/ld.so.cache", O_RDONLY|O_CLOEXEC) = 3
openat(AT_FDCWD, "/usr/lib/tls/x86_64/x86_64/libm.so", O_RDONLY|O_CLOEXEC) = -1 ENOENT (Datei oder Verzeichnis nicht gefunden)
