Hi,
I can see what it is doing but why?
From xxhash.h
/* note: use after variable declarations */
#ifndef XXH_STATIC_ASSERT
# if defined(__STDC_VERSION__) && (__STDC_VERSION__ >= 201112L) /*
C11 */ <<<<<
# define XXH_STATIC_ASSERT_WITH_MESSAGE(c,m) do {
_Static_assert((c),m); } while(0) <<<<< This being picked in error!!!
# elif defined(__cplusplus) && (__cplusplus >= 201103L) /*
C++11 */
# define XXH_STATIC_ASSERT_WITH_MESSAGE(c,m) do {
static_assert((c),m); } while(0) <<<<< Is this correct for Solaris?
# else
# define XXH_STATIC_ASSERT_WITH_MESSAGE(c,m) do { struct xxh_sa {
char x[(c) ? 1 : -1]; }; } while(0)
# endif
# define XXH_STATIC_ASSERT(c) XXH_STATIC_ASSERT_WITH_MESSAGE((c),#c)
#endif
Attached is config.out
Thanks,
Andrew

Hello,
I was looking at moving to Bacula 15.0.3 on our servers, but it does not
build on Solaris 11.4
Version 13.0.4 builds on Solaris.
I get this in xxhash (doesn't look like this is in v13)
In file included from xxhash.c:43:

What C++ compiler & version are you using?
Can you show us the contents of config.out (generated by configure)?
