Qmake pro file variables

Phlucious 3, 23 23 silver badges 54 54 bronze badges. I've staring at each explanation and can't find a single difference I believe they are exactly the same. ZawLin Thanks! I didn't know that. If would be nice if you add what does it actually mean 'at time of qmake' and 'at time of makefile'. I don't know myself, I thought we work with qmake and never worry about makefile.

Podcast Making Agile work for data science. In this case, you can explicitly invoke the all target to build both configurations at once:. When linking a library, qmake relies on the underlying platform to know what other libraries this library links against.

See Platform Notes for more information about the options for embedding manifest files. You may assign anything to this variable.

Specifies preprocessor defines for the debug configuration. This variable is typically set in qmake. Specifies preprocessor defines for the release configuration. Specifies a list of directories for qmake to scan, to resolve dependencies. This variable is used when qmake crawls through the header files that you include in your source code.

Note: The list of supported characters can depend on the used build tool. In particular, parentheses do not work with make. Specifies a list of files to be included in the dist target. This feature is supported by UnixMake specs only. Specifies a list of translation. See the Qt Linguist Manual for more information about internationalization i18n and localization l10n with Qt.

All dependencies, headers and source files required to build these UI files will automatically be added to the project. Specifies the GUID that is set inside a. The GUID is usually randomly determined.

However, should you require a fixed GUID, it can be set using this variable. This variable is used only on Mac OS to set the application icon.

Please see the application icon documentation for more information. This variable is used only on Windows for the Visual Studio project generation to put the specified files in the Generated Files folder. To specify a path containing spaces, quote the path using the technique described in Whitespace. Specifies a list of resources that will be installed when make install or a similar installation procedure is executed.

Each item in the list is typically defined with attributes that provide information about where it will be installed. For example, the following target. For more information, see Installing Files. This variable is also used to specify which additional files will be deployed to embedded devices.

Specifies a list of Lex implementation files. The value of this variable is typically handled by qmake or qmake. Specifies the names of intermediate Lex object files.

The value of this variable is typically handled by qmake and rarely needs to be modified. Specifies a list of Lex source files. All dependencies, headers and source files will automatically be added to the project for building these lex files. Specifies a list of libraries to be linked into the project.

If you use the Unix -l library and -L library path flags, qmake handles the libraries correctly on Windows that is, passes the full path of the library to the linker. The library must exist for qmake to find the directory where a -l lib is located. By default, the list of libraries stored in LIBS is reduced to a list of unique names before it is used.

Specifies a list of libraries to be linked privately into the project. The behavior of this variable is identical to LIBS , except that shared library projects built for Unix do not expose these dependencies in their link interface. The effect of this is that if project C depends on library B which depends on library A privately, but C also wants to use symbols from A directly, it needs to link to A explicitly.

Put differently, libraries linked privately are not exposed transitively at build time. This variable is used whenever a literal hash character is needed in a variable declaration, perhaps as part of a file name or in a string passed to some external application. Specifies the name of the generated Makefile.

Specifies the name of the Makefile generator to use when generating a Makefile. The value of this variable is typically handled internally by qmake and rarely needs to be modified. The extension of each source file is replaced by. You can add objects to the list. Lists the libraries that the target depends on. Some backends, such as the generators for Visual Studio and Xcode project files, do not support this variable. Generally, this variable is supported internally by these build tools, and it is useful for explicitly listing dependent static libraries.

Lists libraries that the target depends on. Indicates the header file for creating a precompiled header file, to increase the compilation speed of a project. Specifies the full path leading to the directory containing the current file being parsed. This can be useful to refer to files within the source tree when writing project files to support shadow builds. Specifies the directory in the resource system where. Specifies the target directory. This variable is only used by Qt Creator.

Specifies the name of the qmake program itself and is placed in generated Makefiles. A system variable that contains the full path of the qmake configuration that is used when generating Makefiles. The value of this variable is automatically computed. Specifies the command to execute when creating a shared library. Specifies the data that will be installed with a library bundle, and is often used to specify a collection of header files. The last line adds the information about the headers to the collection of resources that will be installed with the library bundle.

See Platform Notes for more information about creating library bundles. Specifies the extension to be used for library bundles. This allows frameworks to be created with custom extensions instead of the standard.

For example, the following definition will result in a framework with the. Specifies the C compiler that will be used when building projects containing C source code.

Only the file name of the compiler executable needs to be specified as long as it is on a path contained in the PATH variable when the Makefile is processed. Specifies the C compiler flags for building a project. Specifies the C compiler flags for debug builds.

Specifies the C compiler flags for release builds. Specifies the compiler flags for creating a shared library. Specifies the compiler flags for creating a multi-threaded application. Specifies a list of generated files by moc and uic , for example and object files to be removed by make clean. Contains the extension for shared libraries. Note: Platform-specific variables that change the extension override the contents of this variable.

Contains the extension for shared static libraries. See also File Extensions , Library Dependencies. Contains the list of failed requirements. The value of this variable is set by qmake and cannot be modified.

In a framework project, this variable contains the name to be used for the framework that is built. See Creating Frameworks for more information about creating frameworks and library bundles. For projects where the build target is a macOS, iOS, tvOS, or watchOS framework, this variable is used to specify the version number that will be applied to the framework that is built.

See Creating Frameworks for more information about creating frameworks. Provides information about the host machine running qmake.

Specifies the name of the property list file,. In the. The var style placeholders work only with the qmake Makefile generators and not with the Xcode generator.

If building for iOS, and the. See Info. Specifies a general set of flags that are passed to the linker. If you need to change the flags used for a particular platform or type of project, use one of the specialized variables for that purpose instead of this variable. Specifies the linker flags for building console programs. Specifies the linker flags for debug builds. Specifies the linker flags for building plugins. Specifies the string the dynamic linker understands to be the location of the referring executable or library.

Specifies the linker flags for release builds. Specifies the linker flags for building applications. Specifies the linker flags used for building shared libraries. Specifies the linker flags for setting the name of shared objects, such as. Specifies the linker flags for building multi-threaded projects. Specifies the linker flags for building Windows GUI projects that is, non-console applications. Specifies a list of library search paths for all projects. To specify additional search paths in project files, use LIBS like that, instead:.

Specifies a list of system library search paths for all projects. Specifies the location of all library directories with -L prefixed. Specifies the location of the OpenGL library directory. Specifies the location of the OpenVG library directory. Specifies the location of the X11 library directory. Specifies additional libraries each project needs to link against. To specify libraries in a project file, use LIBS instead.

Specifies additional private libraries each project needs to link against. The usual value is -lEGL. Specifies all OpenGL libraries. The value of these variables is typically handled by qmake or qmake.

Specifies all OpenVG libraries. The usual value is -lOpenVG. Specifies all libraries that need to be linked against when building a multi-threaded target. Specifies all X11 libraries. This variable is not empty if the lib template is specified. Specifies the linker that will be used when building application based projects. Please download a browser that supports JavaScript, or enable it if it's disabled i. I am sorry but I cannot understand how can I use that.

According to the docs that function does something different:. Succeeds if the variable variablename contains the value value; otherwise fails. You can check the return value of this function using a scope. Thank you. Your explanation is useful and clears a few things up but unfortunately I still cannot figure out the answer to my question.
