当我使用-isystem标志而不是INCLUDEPATH时，QtCreator的代码检查器会断开

问题描述

我想要禁止外部程式库的警告，可以我可以使用这样的：

  isCompiling {
 QMAKE_CXXFLAGS + = -isystem ../libs/boost159/ 
} else {
 INCLUDEPATH + = ../libs/boost159/ $为了使QtCreator的解析不会失败，但在编译时， b 
 $ b  


$ b 。任何想法？

如何制作一个条件表达式，只有在QtCreator解析项目文件时才触发/ / p>

解决方案

我发现了解决方案。您需要使用 qmake 其他参数，并指定您选择的变量，然后测试是否已定义。由于QtCreator不知道这些参数，它不会执行用于编译的块：

 ＃这个变量被设置作为CONFIG + = compiling
＃在qmake命令行参数中完成赋值
编译{
＃此块在实际编译期间生效
 QMAKE_CXXFLAGS + = -isystem .. / libs / boost159 / -isystem ../libs/openssl/include 
} else {
＃这个块被QtCreator和其他没有定义CONFIG编译的工具看到
 INCLUDEPATH + = ../libs/boost159/../libs/openssl/include 
} 
  

然后必须在项目管理中进行设置。不要忘记为发布和调试设置：

I wanted to suppress warning from external libraries which can be done by marking them as system libraries. I figured out this is how to do it in .pro QtCreator project file:

QMAKE_CXXFLAGS += -isystem ../libs/boost159/

The problem is that QtCreator relies on the INCLUDEPATH setting, expects this:

INCLUDEPATH += ../libs/boost159/

If I remove it, the QtCreator no longer can find boost libraries:

I originally wanted to report this as a bug but after some reports I no longer believe the QtCreator developers will ever consider fixing this. Instead, I came here for a workaround.

Because qmake has conditional statements I could make use of something like this:

isCompiling {
    QMAKE_CXXFLAGS += -isystem ../libs/boost159/
} else {
    INCLUDEPATH += ../libs/boost159/
}

So that QtCreator's parsing would not fail but upon compile, isystem would be used. Any ideas?

Exoplicitly: How can I make a conditional expression that will only trigger/not trigger when QtCreator is parsing the project file?

解决方案

I have discovered the solution. You need to use qmake additional arguments and specify a variable of your choice, then test if it's defined. Since QtCreator doesn't know about these parameters, it won't execute the block intended for compilation:

# This variable is set as "CONFIG += compiling"
# The assignment is done in qmake command line argument
compiling {
  # This block takes effect during real compilation
  QMAKE_CXXFLAGS += -isystem ../libs/boost159/ -isystem ../libs/openssl/include
} else {
  # This block is seen by QtCreator and other tools that do not have 'CONFIG compiling' defined
  INCLUDEPATH += ../libs/boost159/ ../libs/openssl/include
}

The setting then must be done in project management. Don't forget to set it for both release and debug:
