从程序中获取编译器选项 [英] Get the compiler options from the program

问题描述

c ++中是否有任何宏(使用gcc)来获取用于构建可执行文件的编译选项?我确定我在对话框中看到了类似的内容.

Is there any macro in c++ (using gcc) to get the compilation options used to build the executable ? I'm sure I saw something like that in some about dialogs.

任何帮助将不胜感激

PS:而>检测GCC编译时标志的问题二进制对找到激活的用于编译程序的选项感兴趣，对从该程序源中找到用于编译程序的确切命令行选项很有趣.

PS: while the question in Detect GCC compile-time flags of a binary interests in finding the options activated to compile a program, I'm interesting in finding the exact command line options used to compile my program from within this program source.

推荐答案

因为我使用的是qmake构建系统，所以遇到了以下解决方案:

Because I'm using qmake build system I came across this solution :

我将此行添加到我的专业文件的末尾:

I added this line to the end of my pro file :

QMAKE_CXXFLAGS += -DFLAGS=\"$$QMAKE_CXXFLAGS $$QMAKE_CXXFLAGS_RELEASE\"

然后从FLAGS宏中检索了我想要的内容

then retrieved what I want from the FLAGS macro
