--- Comment #21 from Jonathan Wakely <redi at gcc dot gnu.org> --- Author: redi Date: Thu May 23 15:34:42 2019 New Revision: 271570 URL: https://gcc.gnu.org/viewcvs?rev=271570&root=gcc&view=rev Log: PR libstdc++/89466 avoid slow xsltproc command in configure Certain broken versions of xsltproc ignore the --nonet option and will attempt to fetch the docbook stylesheet from the WWW when it isn't in the local XML catalog. This patch checks for the local stylesheet directory first, and doesn't use xsltproc if no local stylesheets are found. Checking for the local directory is done using xmlcatalog if available, only checking the hardcoded list of directories if xmlcatalog fails. The right directory for Suse is added to the hardcoded list. This should avoid doing an xsltproc check that would need to download the stylesheet, so no network connection is made even if a broken xsltproc is present. Backport from mainline 2019-02-27 Jonathan Wakely <jwak...@redhat.com> PR libstdc++/89466 * acinclude.m4 (GLIBCXX_CONFIGURE_DOCBOOK): Reorder check for local stylesheet directories before check for xsltproc. Try to use xmlcatalog to find local stylesheet directory before trying hardcoded paths. Add path used by suse to hardcoded paths. Adjust xsltproc check to look for the same stylesheet as doc/Makefile.am uses. Don't use xsltproc if xmlcatalog fails to find a local stylesheet. * configure.ac: Check for xmlcatalog. * Makefile.in: Regenerate. * configure: Likewise. * doc/Makefile.in: Likewise. * include/Makefile.in: Likewise. * libsupc++/Makefile.in: Likewise. * po/Makefile.in: Likewise. * python/Makefile.in: Likewise. * src/Makefile.in: Likewise. * src/c++11/Makefile.in: Likewise. * src/c++17/Makefile.in: Likewise. * src/c++98/Makefile.in: Likewise. * src/filesystem/Makefile.in: Likewise. * testsuite/Makefile.in: Likewise.
