[Bug c/84919] [8/9 Regression] error: passing argument 1 to restrict-qualified parameter aliases with argument 5 [-Werror=restrict]
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84919 --- Comment #31 from Marietto --- they don't reply to messages and they don't fix old bugs. And new users aren't interested to use xen anymore. So,it's a waste of time.

Usually packages provide a mechanism to prevent compiler warnings from causing errors (by avoiding -Werror). I don't know how this one does it. I'd try adding WERROR=0 to the invocation of the command you are using to build it. The link is a diff from a Wiki edit, not a guide. This also isn't the right place to get help with third party software. I'd talk to the Intel GVT-g developers.

The fix was applied to GCC 10 but not to GCC 9 or 8. It will not be backported
there. It can be suppressed by introducing a named temporary copy of the
pointer and using it as one other other argument to the function.
void f (char *p)
{
char *q = p;
sprintf (p, "%p", q);
}

I'm trying to configure and compile GVT-g to enable the passthrough of the integrated GPU that I have on my motherboard,the model "Intel Corporation UHD Graphics 630 (Desktop 9 Series) (rev 02)". This is the tutorial that I'm following : https://lists.freedesktop.org/archives/intel-gvt-dev/2017-June/001238.html I reached this point and then the compilation stopped for an error that it seems to be the same as this. root@ziomario-z390aoruspro:/etc/xen/gvt-linux# make CHK include/config/kernel.release CHK include/generated/uapi/linux/version.h CHK include/generated/utsrelease.h CHK include/generated/timeconst.h CHK include/generated/bounds.h CHK include/generated/asm-offsets.h CALLscripts/checksyscalls.sh DESCEND objtool CC /etc/xen/gvt-linux/tools/objtool/pager.o CC /etc/xen/gvt-linux/tools/objtool/parse-options.o CC /etc/xen/gvt-linux/tools/objtool/run-command.o CC /etc/xen/gvt-linux/tools/objtool/sigchain.o CC /etc/xen/gvt-linux/tools/objtool/subcmd-config.o LD /etc/xen/gvt-linux/tools/objtool/libsubcmd-in.o AR /etc/xen/gvt-linux/tools/objtool/libsubcmd.a GEN /etc/xen/gvt-linux/tools/objtool/arch/x86/insn/inat-tables.c CC /etc/xen/gvt-linux/tools/objtool/arch/x86/decode.o LD /etc/xen/gvt-linux/tools/objtool/arch/x86/objtool-in.o CC /etc/xen/gvt-linux/tools/objtool/builtin-check.o CC /etc/xen/gvt-linux/tools/objtool/elf.o CC /etc/xen/gvt-linux/tools/objtool/special.o CC /etc/xen/gvt-linux/tools/objtool/objtool.o CC /etc/xen/gvt-linux/tools/objtool/libstring.o CC /etc/xen/gvt-linux/tools/objtool/str_error_r.o ../lib/str_error_r.c: In function ‘str_error_r’: ../lib/str_error_r.c:24:3: error: passing argument 1 to restrict-qualified parameter aliases with argument 5 [-Werror=restrict] 24 | snprintf(buf, buflen, "INTERNAL ERROR: strerror_r(%d, %p, %zd)=%d", errnum, buf, buflen, err); | ^~~~ cc1: all warnings being treated as errors mv: impossibile eseguire stat di '/etc/xen/gvt-linux/tools/objtool/.str_error_r.o.tmp': File o directory non esistente make[3]: *** [Build:18: /etc/xen/gvt-linux/tools/objtool/str_error_r.o] Errore 1 make[2]: *** [Makefile:40: /etc/xen/gvt-linux/tools/objtool/objtool-in.o] Errore 2 make[1]: *** [Makefile:61: objtool] Errore 2 make: *** [Makefile:1616: tools/objtool] Errore 2 I don't understand where is the patch ?
