QT pro文件中的多个条件

Question

如何检查QT pro文件中的多个条件？ 例如，如何在下面的代码段中添加多个条件。

DEFINES += QT_FORCE_ASSERTS

win32 {
    CURR_PLATFORM = $$(CURR_PLATFORM) # read from environment
    CURR_ARCH = $$(CURR_ARCH) # read from environment
    !(equals(CURR_PLATFORM, "win32") && equals(CURR_ARCH, "x64")){
        error(CURR_PLATFORM must be set to \"win32\" currently set to: \"$$(CURR_PLATFORM)\")
    }
}

Answer 1

将:用作“和”，将|用作“或”。但是，您不能将它们放在括号内。所以这行不通：

!(equals(CURR_PLATFORM, "win32") : equals(CURR_ARCH, "x64")) { ... }

您必须进行更改以消除括号：

!equals(CURR_PLATFORM, "win32") | !equals(CURR_ARCH, "x64") { ... }
