Bug ID: 89466 Summary: Accessing the Internet while boostrapping Product: gcc Version: unknown Status: UNCONFIRMED Severity: blocker Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: tkoenig at gcc dot gnu.org Target Milestone: --- I finally got around to checking what was holding up the bootstrap process for so long while the message "checking for docbook stylesheets for documentation creation" was displayed. Apparently, the configure script downloads something from the Internet using xsltproc --noout --nonet --xinclude http://docbook.sourceforge.net/release/xsl-ns/current/xhtml-1_1/docbook.xsl Now, this has several problems. First, connecting to somehwere external should be under the user's control, no software package should be doing so during compilation by default. There is such a thing as data privacy. If a source file is needed during compilation, include it in the first place. Second, this takes far too much time. Third, this is run repeatedly in several states during bootstrapping. As to why I mark this a "blocker": This is a serious obstacle to my further contribution to gcc.
