Hello,
sarg FTBFS in Ubuntu Impish (development version), which uses GCC 10.3 because of the way variables are declared inside include/conf.h.
It's a bad practice to declare variables inside a header file, because they get included as-is into the C file which means that the variables get redeclared on every compilation unit. Instead, these variables should be marked as "extern" and be declared inside a C file.
If you would like to see the build log with the compilation failure, you can go to:
Thanks.
