I see that you're trying to compile also the c++ compiler. You have to add --disable-libsanitizer and --disable-libmpx to the configure step, it will fail otherwise > > 在 2019/10/15 上午12:48，“Clfs-support 代表 Andrew Bradford”< > [email protected] 代表 [email protected]> 写入: > > Hi, > > On Mon, Oct 14, 2019 at 11:27 AM DELUGE <[email protected]> wrote: > > When I build gcc 6.2 following > http://clfs.org/view/clfs-embedded/x86/cross-tools/gcc-static.html on > Ubuntu 19.04 using gcc 8.3, > > The error below occurred.
