In \QC, a \l{glossary-buildandrun-kit}{kit} specifies the compiler and other necessary tools for building and running an application on a particular platform. \QC automatically detects the compilers that are registered by your system or by an installer. You can add compilers to build applications by using other compilers or by using additional versions of the automatically detected compilers: \list \li GNU Compiler Collection (GCC) is a compiler for Linux and Mac OS X. \li MinGW (Minimalist GNU for Windows) is a native software port of GCC and GNU Binutils for use in the development of native Microsoft Windows applications on Windows. MinGW is distributed together with \QC and Qt installers for Windows. \li Linux ICC (Intel C++ Compiler) is a group of C and C++ compilers for Linux. \li Clang is a C, C++, Objective C, and Objective C++ front-end for the LLVM compiler for Windows, Linux, and Mac OS X. \endlist To build an application using GCC, MinGW, or Clang, specify the path to the directory where the compiler is located and select the application binary interface (ABI) version from the list of available versions. You can also create a custom ABI definition. You specify the compiler to use for each kit in \gui Tools > \gui Options > \gui {Build & Run} > \gui Kits. To add compilers: \list 1 \li Select \gui {Tools > Options > Build & Run > Compilers > Add} and select a compiler in the list. \image qtcreator-toolchains.png To clone the selected compiler, select \gui {Clone}. \li In the \gui Name column, double-click the name to change it. \li In the \gui{Compiler path} field, enter the path to the directory where the compiler is located. \li In the \gui {Platform codegen flags} field, check the flags passed to the compiler that specify the architecture on the target platform. \li In the \gui {Platform linker flags} field, check the flags passed to the linker that specify the architecture on the target platform. The linker flags are used only when building with Qbs. The other settings to specify depend on the compiler. \endlist \section1 Adding Custom Compilers To add a compiler that is not listed above or a remote compiler, use the \gui Custom option and specify the paths to the directories where the compiler and make tool are located and options for the compiler. \image creator-compilers-custom.png To add other compilers: \list 1 \li Select \gui Tools > \gui Options > \gui {Build & Run} > \gui Compilers > \gui Add > \gui Custom. \li In the \gui Name field, enter a name for the compiler. \li In the \gui {Compiler path} field, enter the path to the directory where the compiler is located. \li In the \gui {Make path} field, enter the path to the directory where the make tool is located. \li In the \gui ABI field, specify the ABI version. \li In the \gui {Predefined macros} field, specify the macros that the compiler enables by default. Specify each macro on a separate line, in the following format: MACRO[=value]. \li In the \gui {Header paths} field, specify the paths to directories that the compiler checks for headers. Specify each path on a separate line. \li In the \gui {C++11 flags} field, specify the flags that turn on C++11 support in the compiler. \li In the \gui {Qt mkspecs} field, specify the path to the directory where mkspecs are located. Usually, the path is specified relative to the Qt mkspecs directory. \li In the \gui {Error parser} field, select the error parser to use. Select \gui Custom, and then select \gui {Customer Parser Settings} to specify settings for a custom parser: \image qtcreator-custom-parser.png \list 1 \li In the \gui {Error message capture pattern} field, specify a regular expression to define what is an error. The custom parser matches the compile output line by line against the regular expression and displays errors in the \gui Issues output pane. Create regular expression groups that contain the file name, line number and error message. \li In the \gui {Capture Positions} field, map the regular expression groups to \gui {File name}, \gui {Line number}, and \gui Message. \li In the \gui {Test} group, you can test how the message that you enter in the \gui {Error message} field is matched when using the current settings. \endlist \endlist \section1 Troubleshooting MinGW Compilation Errors If error messages displayed in the \gui {Compile Output} pane contain paths where slashes are missing (for example, C:QtSDK), check your PATH variable. At the command line, enter the following commands: \code where sh.exe where make.exe where mingw32-make.exe \endcode If these commands show paths, they have been added to the global PATH variable during the installation of a tool chain based on Cygwin or MinGW, even though this is against Windows conventions. To keep working with the third-party tool chain, create a new shell link that adds the required paths (as Visual Studio and Qt do). The shell link must point to cmd.exe, as illustrated by the following example: \c {C:\Windows\System32\cmd.exe /K C:\path_to\myenv.bat} where the /K parameter carries out the command specified in the bat file. Create the myenv.bat file at \e path_to, which should be in a convenient location. In the file, specify the paths to the tool chains. For example, \c {set PATH=C:\path1;C:\path2;%PATH%} where \e path1 and \e path2 are paths to the tool chains. Finally, remove the paths from the global PATH, reboot the computer, and run the \c where commands again to verify that the global PATH is now clean. You can use the shell link to run the tools in the third-party tool chains. */
