--- Comment #23 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-10 branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:8da8ed881e7cdb2d4b070d685d6d3fe8d31529c2 commit r10-10601-g8da8ed881e7cdb2d4b070d685d6d3fe8d31529c2 Author: Jonathan Wakely <jwak...@redhat.com> Date: Wed Apr 13 14:09:33 2022 +0100 libstdc++: Use LTLIBICONV when linking libstdc++.so [PR93602] This fixes missing libiconv symbols when libstdc++ is built on a system that has libiconv installed. If the libiconv headers are found then libstdc++ depends on libiconv_open etc instead of libc's iconv_open. But without this fix libstdc++ is not linked to the libiconv library that provides the definitions of those symbols. As discussed in PR 93602 this changed means that libstdc++.so.6 might have an rpath pointing to the location of the libiconv.so library. If that is not desired, then GCC must be configured to link to a static libiconv.a instead, using either --with-libiconv-type=static or an in-tree build of libiconv. libstdc++-v3/ChangeLog: PR libstdc++/93602 * doc/xml/manual/prerequisites.xml: Document libiconv workarounds. * doc/html/manual/setup.html: Regenerate. * src/Makefile.am (CXXLINK): Add $(LTLIBICONV). * src/Makefile.in: Regenerate.
