Re: Bugreport: Incorrect forwarding of a shared library's -R flags when this library is linked to an executable

[Stefan Muller]

Bob,

Thanks for your reply. However, I downloading the official FSF version of libtool from

http://ftp.gnu.org/gnu/libtool/libtool-2.2.6b.tar.gz

is what I tried first. I compiled from sources and installed the official libtool in /usr/local, which overrides the ubuntu installation in /usr. Below is the diff of the two versions of ltmain.sh - both versions have the "-R*) ;;" line (#6002 and #6005, respectively), which makes my executables link incorrectly.

Thanks,

Stefan

Please make sure that you are using the official FSF-released version of libtool rather than a modified one.  It looks to me like you are using one which has been modified by the libtool package maintainer for your operating system.  This sort of modification is common.

The easiest approach is to install official FSF autoconf, automake, and libtool, all under the same prefix, but using a different prefix than the ones provided with your operating system.  Then set your path to use the versions you installed.
