you may need to patch some xenstore files if you face the xprintf compile error:

https://lists.xenproject.org/archives/html/xen-devel/2020-05/msg01273.html

on xenstored_core.h:

extern xengnttab_handle **xgt_handle;

on utils.h:

extern void (*xprintf)(const char *fmt, ...);

If you find something like “cc1: all warnings being treated as errors”

• just open the makefile of the directory referenced by the error and remove the -Werror from CFLAGS
• To find the directory, look for the last make[4]: Entering directory ocurrence that was printed on the stdout
  • For Example:
    • make[4]: Entering directory '/home/sargx/Workspace/TCC/xenonarm/xen-4.12.2/tools/libxl
    • In this case, edit tools/libxl/Makefile.

CFLAGS += -Werror
