Subject: [PATCH] skipping of incompatible libraries in the search path
Date: Mon, 05 Jul 1999 09:37:00 -0000 [thread overview]
Message-ID: <19990705183746.D1736@mff.cuni.cz> (raw)
Hi!
This is a patch for how I think the skip on mismatch discussion ended.
It makes ld skip incompatible libraries unconditionally, but lets the user
know about it whenever it happens. If the user wants to force linking an
incompatible library in, he has to request it by supplying full path to the
library.

* ld/ldfile.c (ldfile_open_file_search): Skip libraries made for
incompatible architectures in the search path. Let the user know
about any such skips.
