Red Hat Bugzilla – Bug 56072
libtool warnings from every C++ app
Last modified: 2008-05-01 11:38:01 EDT
Description of Problem: Every application using libtool and C++ gets the following warning during linking: libtool: link: warning: library `/usr/lib/gcc-lib/i386-redhat-linux/3.1/libstdc++.la' was moved. dependency_libs= in the file holds references to the build root: dependency_libs=' -L/usr/src/redhat/BUILD/gcc-3.1-20011112/obj-i386-redhat-linux/i386-redhat-linux/libstdc++-v3/src -L/usr/src/redhat/BUILD/gcc-3.1-20011112/obj-i386-redhat-linux/i386-redhat-linux/libstdc++-v3/src/.libs -lm -lm -lm -L/usr/src/redhat/BUILD/gcc-3.1-20011112/obj-i386-redhat-linux/gcc -L/usr/lib/gcc-lib/i386-redhat-linux/3.1 -L/usr/lib/gcc-lib/i386-redhat-linux/3.1/../../.. -lgcc -lc -lgcc -lm -lgcc -lc -lgcc' and libdir='/usr/lib' points to the wrong place. Affects libsupc++ as well. Suggested quickfix: perl -pi -e "s,^libdir=.*,libdir='/usr/lib/gcc-lib/%{_arch}-redhat-linux/%{version},;s,$RPM_BUILD_ROOT,,;" $RPM_BUILD_ROOT/usr/lib/gcc-lib/%{_arch}-redhat-linux/%{version}/*.la Similarily, I think the loads of references to -lgcc should be replaced with just one. Alternatively, simply remove the *.la files, libtool sucks anyway, and doesn't have much of a point on sane OSes. ;) Version-Release number of selected component (if applicable): 3.1-0.7
Do you have a preprocessed testcase, please?
Oops, this was meant for different bug. Sorry. .la files are already removed in my .spec file.
If your comment was meant for #56073, what exactly do you need? Something using __attribute__ alias or something trying to link to it? I'm not familiar with gcc __attribute__ internals.
