Qt .pro文件-如何在OSX版本上添加条件？ [英] Qt .pro file - how to add conditioning on OSX version?

问题描述

我在两个开发机器之间共享一个Qt代码库。一种是OSX 10.8.5，一种是OSX 10.9.5。

I have a Qt codebase shared between two development machines. One is OSX 10.8.5 and one is OSX 10.9.5.

除非包含以下内容，否则该项目不会在10.9.5上编译：

The project won't compile on 10.9.5 unless I include:

QMAKE_MAC_SDK = macosx10.9

QMAKE_MAC_SDK = macosx10.9

因此，我有两个.pro文件，一个带有/不带有该行。

and thus I have two .pro files, one with/without that line. How can I have the .pro file conditionally include that line depending on the version of Mac OSX detected?

推荐答案

我最近如何找到.pro文件，如何根据检测到的Mac OSX版本有条件地包括该行？ 信息，它似乎是可行的（已应用

I recently found some info on that and it appears to be doable (applied once) with:

OS_VERSION = $$system(uname -r)                             # common to Unix
contains(OS_VERSION, VersionTag):SOURCES += example.c       # can apply to different options
contains(OS_VERSION, VersionTag):QMAKE_MAC_SDK = macosx10.9 # like that?

正在回答Tay2510，出于某种原因，只有完整的字符串在Linux上有效：

Answering Tay2510, for some reason only full string worked on Linux:

OS_VERSION = $$system(uname -r)
message($$OS_VERSION)
contains( OS_VERSION, 3.13.0-39-generic ) {
    message(Generic)
}

#Output:

Project MESSAGE: 3.13.0-39-generic
Project MESSAGE: Generic
