Build failure with gcc 15+ #27
Description
Building with gcc v15 and above leads to errors like these:
../../../../../repos/exafmm-t/include/exafmm_t.h:106:5: error: ‘uint64_t’ does not name a type [-Wtemplate-body]
106 | uint64_t key; //!< Morton key
| ^~~~~~~~
../../../../../repos/exafmm-t/include/exafmm_t.h:15:1: note: ‘uint64_t’ is defined in header ‘<cstdint>’; this is probably fixable by adding ‘#include <cstdint>’
14 | #include "vec.h"
+++ |+#include <cstdint>
The fix is straightforward: add #include <cstdint> to exafmm_t.h.
Further discussion here.
