--- Comment #3 from Bruno Haible <bruno at clisp dot org> --- Created attachment 52955 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=52955&action=edit Patch to document also --with-zstd-include and --with-zstd-lib Hi Martin, The patch you added is pretty minimal: it refers to undocumented options --with-zstd-include and --with-zstd-lib; it suggests that --with-zstd can be used without an argument; and it does not clarify how this option applies to cross-compilation. How about adding the same details as for the --with-isl, --with-isl-include, --with-isl-lib options, mutatis mutandis? Find attached a patch that does that.
