This page describes the procedure to follow when cross compiling for another system.
In this page, we will refer to the system as:
- Target System: The system where the executables are intended to run.
- Build System: The system where the executables are built.
In Linux Host for Mac Target
In this particular case we illustrate
- Target System = Mac
- Build System = Linux
Major steps
- Build your tool chain in the build system
- This is the set of compiler and linker that must be build in the build system, but will know how to generate code for the Target system.
- Create a TryRun ... file in the native system
- This could be generated (as a skeleton) with the following commands
Building the ToolChain for Darwin
The following is a script developed by Johannes Schindelin (originally intended for FIJI)
Script for Building the Darwing Toolchain in Linux
Following the advice of the CMake Wiki [1]
Put the following in a file called ToolChain.cmake
# this one is important SET(CMAKE_SYSTEM_NAME Linux) #this one not so much SET(CMAKE_SYSTEM_VERSION 1) # specify the cross compiler SET(CMAKE_C_COMPILER /usr/bin/gcc) SET(CMAKE_CXX_COMPILER /usr/bin/g++) # where is the target environment SET(CMAKE_FIND_ROOT_PATH /usr) # search for programs in the build host directories SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) # for libraries and headers in the target directories SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
and run it with CMake using the command (in an empty directory)
cmake -DCMAKE_TOOLCHAIN_FILE=./ToolChain.cmake ~/src/ITK
This will generate (among many other things) a File called
TryRunResults.cmake
Then, manually populate, the values of each one of the fields.
- Copy the file to the build system
- Do the command in the build system.
cmake -C ~/TryRunResults.cmake .
The full process scripted
The process as a whole has been scripted in the file below

Thanks to Johannes Schindelin for contributing the script.
In Linux Host for Windows Target
In this particular case we illustrate
- Target System = Windows
- Build System = Linux
Major steps
- Build your tool chain in the build system
- This is the set of compiler and linker that must be build in the build system, but will know how to generate code for the Target system.
- In this case we use MinGW as the tool chain
- Create a TryRun ... file in the native system
- This could be generated (as a skeleton) with the following commands
