Subject: libtool: Pass the "-no-canonical-prefixes" linker flag
X-Git-Tag: v2.5.0~10
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=297b5cf19fe12bbee1322a17ff013a21f57bb93d;p=thirdparty%2Flibtool.git

libtool: Pass the "-no-canonical-prefixes" linker flag

When using the -no-canonical-prefixes flag in libtool, the flag is
removed from the linking command, causing linking to fail. This adds
the flag to the list of linker flags to be passed through to the
linker.

* build-aux/ltmain.in: Pass -no-canonical-prefixes to the linker.
* Makefile.am: Added in tests/bug_62343.at.
* tests/bug_62343.at: Contains test case for bug 62343.
