\title Adding Compilers
Qt is supported on a variety of 32-bit and 64-bit platforms, and can
usually be built on each platform with GCC, a vendor-supplied compiler, or
a third party compiler. 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
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 OS X.
\li QCC is the interface for compiling C++ applications for QNX.
\endlist
To build an application using GCC, MinGW, Clang, or QCC, 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.
For QCC, also specify the path to the BlackBerry NDK or the QNX Software
Development Platform (SDP).
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.
