如何指示 Qt Creator PRO 文件在单独的文件夹中输出 .o 文件和 moc_ 文件？

目前，QtCreator 在应用程序的根文件夹中创建 .o 和 moc_ 文件。如何指示项目文件将它们放入名为“obj”的子文件夹中？

您可以使用 OBJECTS_DIR 和 MOC_DIR 变量来实现此目的。例如，Qt 本身在构建时会执行类似的操作：

OBJECTS_DIR = .obj
MOC_DIR     = .moc

在这种情况下，我认为 .obj、.moc 目录是相对于包含 Makefile 的目录的。

You can use the OBJECTS_DIR and MOC_DIR variables for this. e.g. Qt itself does something like this while building:

OBJECTS_DIR = .obj
MOC_DIR     = .moc

In this case I think the .obj, .moc directories are relative to the directory containing the Makefile.

为了保持主（源）文件夹中没有二进制文件和生成的文件，您可以将以下几行放入“myapp.pro”文件中：

DESTDIR = ../../bin
UI_DIR = .

CONFIG(debug, debug|release) {
        TARGET = myappd
        OBJECTS_DIR = ../../build/myapp/debug
        MOC_DIR = ../../build/myapp/debug
}

CONFIG(release, debug|release) { 
        TARGET = myapp
        OBJECTS_DIR = ../../build/myapp/release
        MOC_DIR = ../../build/myapp/release
}

上述设置意味着以下目录结构：

myprojects/source/myapp/   => containing myapp.pro + all other project files hpp, cpp etc.
myprojects/bin/  => containing myapp.exe & myappd.exe application files
myprojects/build/myapp/release  => object files + moc files (release)
myprojects/build/myapp/debug   => object files + moc files (debug)

如果不存在，将自动创建最后 3 个目录存在。

这种模式的优点是：

a．您可以将您的项目（myapp 目录）移动到另一个父目录，由于 bin & 的相对规范，它将继续构建正常。构建目录

B.您可以在 myprojects/source/c 下添加更多子项目

。您可以备份（例如 ZIP）所有 myprojects/source/ 目录，而不包含任何二进制文件或生成的文件

To keep your main (source) folder clean of binary and generated files you can put the following lines in your "myapp.pro" file:

DESTDIR = ../../bin
UI_DIR = .

CONFIG(debug, debug|release) {
        TARGET = myappd
        OBJECTS_DIR = ../../build/myapp/debug
        MOC_DIR = ../../build/myapp/debug
}

CONFIG(release, debug|release) { 
        TARGET = myapp
        OBJECTS_DIR = ../../build/myapp/release
        MOC_DIR = ../../build/myapp/release
}

The above settings imply the following directory structure:

myprojects/source/myapp/   => containing myapp.pro + all other project files hpp, cpp etc.
myprojects/bin/  => containing myapp.exe & myappd.exe application files
myprojects/build/myapp/release  => object files + moc files (release)
myprojects/build/myapp/debug   => object files + moc files (debug)

The last 3 directories will be automatically created if they do not exist.

The advantages of this schema is:

a. You can move your project (myapp directory) to another parent directory and it will continue to build OK due to the relative specification of bin & build directories

b. You can add more sub-projects under myprojects/source/

c. You can backup (e.g. ZIP) all of myprojects/source/ directory without including any binary or generated files
