Subject: ld-wrapper does not handle all possibilities to specify libraries and
 their search paths
Date: Sun, 2 Jun 2024 15:29:34 +0200

Hi!

Beside using an absolute path, the ld of Binutils has eight ways¹ to pass a library like libfoo.so via options:

-lfoo
-l foo
-library=foo
--library=foo
-l:libfoo.so
-l :libfoo.so
-library=:libfoo.so
--library=:libfoo.so

The ld-wrapper however only supports one of these possibilities, which is the most common: -lfoo. GCC itself does not support the -[-]library= variants.


Similarly there are four ways to specify a library search path /bar for ld:

-L/bar
-L /bar
-library-path=/bar
--library-path=/bar

The ld-wrapper only supports the first two. GCC itself does not support the -[-]library-path= variant.


The lld form the LLVM project supports all these different options as well.


Bye

Stefan
