当你在编译或配置某个项目时遇到 configure: error: uint64_t or int64_t not found 错误,这通常意味着编译器找不到定义 uint64_t 和int64_t 数据类型的头文件。这些类型通常定义在 <stdint.h> 中,这是一个C99标准引入的头文件。以下是一些解决这个问题的步骤: 确认错误信息的上下文环境: 这个错误...
即 0 ~ 255，共 256 个数；int 类型占 32 个比特位，那么 unsigned 类型所能表示的数的范围为 0...
假设我有一个 PostgreSQL 数据库,并且我将 int64_t 或 uint64_t 的最大值存储在 NUMERIC 类型的列中(我无法使用 BIGINT 类型,因为 PostgreSQL 中没有 uint64_t 的无符号变体)。 查看https://doc.qt.io/qt-6/sql-types.html#postgresql-data-types,似乎NUMERIC映射到qreal(= double),这显然不会能够在不...
另外,针对ssize_t(有符号的size_t)可以使用: %zu来格式化。 而int64_t可以使用C99标准的: %jd,uint64_t可以使用:%ju 注意:VS2013并不支持,上述C99标准。

ax_create_stdint_h.m4 (the thing that makes qthread-int.h) does a pretty good job of making sure uint64_t is found if it's availble on a machine. qthreads uses uint64_t a bunch of other places anyways, so if it's truly not availble, a lot more than just qt_gcd is going ...
