看报错提示是WebGLPlugins\i64lib.c文件409行附近不符合C++11语法

https://github.com/Tencent/xLua/blob/ad3733c7f0374e632df667430327d362507958da/WebGLPlugins/i64lib.c#L409

多加一个空格就能编译了

static int uint64_tostring(lua_State* L) {
    char temp[72];
    uint64_t n = lua_touint64(L, 1);
#if ( defined (_WIN32) ||  defined (_WIN64) ) && !defined (__MINGW32__) && !defined (__MINGW64__)
    sprintf_s(temp, sizeof(temp), "%" PRIu64, n);
#else
    snprintf(temp, sizeof(temp), "%" PRIu64, n);
#endif

    lua_pushstring(L, temp);

    return 1;
}
