I'm trying to compile Perl bindings to Nvidia Management library (NVML). When I use the makefile, following errors appear:

/usr/lib/powerpc64le-linux-gnu/perl/5.22/CORE/handy.h:117:34: error: ‘bool’ undeclared (first use in this function)
 #define cBOOL(cbool) ((cbool) ? (bool)1 : (bool)0)

/usr/lib/powerpc64le-linux-gnu/perl/5.22/CORE/handy.h:117:39: error: expected ‘:’ before numeric constant
 #define cBOOL(cbool) ((cbool) ? (bool)1 : (bool)0)

gcc version is: gcc (Ubuntu/IBM 5.4.0-6ubuntu1~16.04.2) 5.4.0 20160609

I've included stdbool.h file in handy.h.

Do you mean you've edited `handy.h` manually? – melpomene Sep 03 '16 at 13:54
yes. Instead, should I add some flag in makefile? – user3509540 Sep 03 '16 at 14:13
What are the preceding 40 or so lines of `handy.h`? – melpomene Sep 03 '16 at 14:55
This file already contains plenty of logic to handle bool, you would need to (revert to the original file and) check what exactly is going on, what does HAS_BOOL expand to? I_STDBOOL? PERL_BOOL_AS_CHAR? etc. – Marc Glisse Sep 03 '16 at 16:03
Yes, from the logic it seems it should handle bool. Has the errors anything to do with gcc version/packages? Also how to check what HAS_BOOL expands to? – user3509540 Sep 05 '16 at 05:48
