如何从 C++ 程序中检索 Poco 库版本?
How to retrieve Poco libraries version from inside a C++ program?
C++ Poco 库在返回库当前版本的源代码中是否有任何宏或常量?
Poco::Environment
class 有一个静态成员函数 libraryVersion()
:
#include "Poco/Environment.h"
#include "Poco/Format.h"
// ...
std::string version = Poco::format("%d.%d.%d",
static_cast<int>(Poco::Environment::libraryVersion() >> 24),
static_cast<int>((Poco::Environment::libraryVersion() >> 16) & 0xFF),
static_cast<int>((Poco::Environment::libraryVersion() >> 8) & 0xFF));
值取自Poco/Version.h
中的POCO_VERSION
宏:
// Version format is 0xAABBCCDD, where
// - AA is the major version number,
// - BB is the minor version number,
// - CC is the patch version number, and
// - DD is the pre-release designation/number.
// The pre-release designation hex digits have a special meaning:
// 00: final/stable releases
// Dx: development releases
// Ax: alpha releases
// Bx: beta releases
//
#define POCO_VERSION 0x01090000
