问题描述
我需要弄清楚我的程序在运行时正在运行的操作系统.
I need to figure out the operating system my program is running on during runtime.
我正在将Qt 4.6.2，MinGW和Eclipse与CDT一起使用.我的程序应在Windows或Linux上运行命令行QProcess.现在，我需要一种开关来根据操作系统运行不同的代码.
I'm using Qt 4.6.2, MinGW and Eclipse with CDT. My program shall run a command-line QProcess on Windows or Linux. Now I need a kind of switch to run the different code depending on the operating system.
Thx
推荐答案
实际上，操作系统是由Q_OS _...宏定义的.只是说而已. Q_WS _...是窗口系统.不完全一样. (我正在阅读问题作者的文章....操作系统".)
Actually the Operating System is defined by the Q_OS_... macros. Just saying. The Q_WS_... are windowing system. Not exactly the same. (I'm just reading what the author of the question wrote.... "operating system".)
这些声明可在qglobal.h文件中找到.
These declarations are found in the qglobal.h file.
Use Q_OS_x with x being one of:
DARWIN - Darwin OS (synonym for Q_OS_MAC)
SYMBIAN - Symbian
MSDOS - MS-DOS and Windows
OS2 - OS/2
OS2EMX - XFree86 on OS/2 (not PM)
WIN32 - Win32 (Windows 2000/XP/Vista/7 and Windows Server 2003/2008)
WINCE - WinCE (Windows CE 5.0)
CYGWIN - Cygwin
SOLARIS - Sun Solaris
HPUX - HP-UX
ULTRIX - DEC Ultrix
LINUX - Linux
FREEBSD - FreeBSD
NETBSD - NetBSD
OPENBSD - OpenBSD
BSDI - BSD/OS
IRIX - SGI Irix
OSF - HP Tru64 UNIX
SCO - SCO OpenServer 5
UNIXWARE - UnixWare 7, Open UNIX 8
AIX - AIX
HURD - GNU Hurd
DGUX - DG/UX
RELIANT - Reliant UNIX
DYNIX - DYNIX/ptx
QNX - QNX
QNX6 - QNX RTP 6.1
LYNX - LynxOS
BSD4 - Any BSD 4.4 system
UNIX - Any UNIX BSD/SYSV system
窗口系统定义如下:
Use Q_WS_x where x is one of:
MACX - Mac OS X
MAC9 - Mac OS 9
QWS - Qt for Embedded Linux
WIN32 - Windows
X11 - X Window System
S60 - Symbian S60
PM - unsupported
WIN16 - unsupported
使用#ifdef的主要问题之一是确保如果您在新"平台上进行编译(从未在该平台上编译过该软件)，则您希望使用#elif defined(...)和至少一个#else + #error ...
One of the main problems with using #ifdef is to make sure that if you compile on a "new" platform (never compiled that software on that platform) then you want to use #elif defined(...) and at least an #else + #error ...
#ifdef W_OS_LINUX
std::cout << "Linux version";
#elif defined(W_OS_CYGWIN)
std::cout << "Cygwin version";
#else
#error "We don't support that version yet..."
#endif
