I am attempting to build jsvc under Ubuntu 25.10 using the default system
compiler, GCC 15.2.0. The build fails with the following error:
In file included from jsvc-unix.c:17:
jsvc.h:32:5: error: cannot use keyword ‘false’ as enumeration constant
32 | false,
| ^~~~~
jsvc.h:32:5: note: ‘false’ is a keyword with ‘-std=c23’ onwards
jsvc.h:34:3: error: expected ‘;’, identifier or ‘(’ before ‘bool’
34 | } bool;
| ^~~~
jsvc.h:34:3: warning: useless type name in empty declaration
This stems from these lines near to top of jsvc.h:
#ifdef OS_DARWIN
#include <stdbool.h>
#else
typedef enum {
false,
true
} bool;
#endif
I believe that the line "#ifdef OS_DARWIN" should be replaced by something like
this:
#if defined(__STDC_VERSION__) && (__STDC_VERSION__ >= 199901L) /* C99 */
so that stdbool.h is included for all C99-conforming compilers, not just
Apple's clang.
Thanks,
Ian
