--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Rainer Orth <r...@gcc.gnu.org>: https://gcc.gnu.org/g:a20893cf6b95f60f5319b2196621acc65180125c commit r11-6457-ga20893cf6b95f60f5319b2196621acc65180125c Author: Rainer Orth <r...@cebitec.uni-bielefeld.de> Date: Tue Jan 5 11:32:31 2021 +0100 build: libcody: Link with -lsocket -lnsl if necessary [PR98316] With the introduction of C++20 modules and libcody, cc1plus and cc1objplus gained a dependency on the socket functions. Before those were merged into libc in Solaris 11.4, one needed to link with -lsocket -lnsl on Solaris, so that merge broke the Solaris 11.3 build. While we already have 4 different checks for those libraries in the tree, I decided to import autoconf-archive's AX_LIB_SOCKET_NSL macro instead. At the same time, the patch only links libcody and the networking libs where needed (cc1plus, cc1objplus). Bootstrapped without regressions on i386-pc-solaris2.11 (Solaris 11.3 and 11.4), sparc-sun-solaris2.11, and x86_64-pc-linux-gnu. 2020-12-16 Rainer Orth <r...@cebitec.uni-bielefeld.de> c++tools: PR c++/98316 * configure.ac: Include ../config/ax_lib_socket_nsl.m4.
