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 <ro@CeBiTec.Uni-Bielefeld.DE> c++tools: PR c++/98316 * configure.ac: Include ../config/ax_lib_socket_nsl.m4.

# SYNOPSIS
|
|
#
|
|
# AX_LIB_SOCKET_NSL
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# This macro figures out what libraries are required on this platform to
|
|
# link sockets programs.
|
|
#
|
|
# The common cases are not to need any extra libraries, or to need
|
|
# -lsocket and -lnsl. We need to avoid linking with libnsl unless we need
|
|
# it, though, since on some OSes where it isn't necessary it will totally
|
|
# break networking. Unisys also includes gethostbyname() in libsocket but
|
|
# needs libnsl for socket().
