This directory contains a collection of toolchain definitions for
|
||||||
compilation, currently limited to compiling Win32 binaries on Linux.
|
cross-compiling for Windows using MinGW on various other systems.
|
||||||
|
|
||||||
The toolchain file naming scheme is as follows:
|
|
||||||
|
|
||||||
host-system-compiler.cmake
|
|
||||||
|
|
||||||
To use these files you add a special parameter when configuring the source tree:

To use these files you add a special parameter when configuring the source tree:
|

|
|

cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
|
cmake -DCMAKE_TOOLCHAIN_FILE=<toolchain-file> .
|
||||||
|
|
||||||
For example, to use the Debian GNU/Linux MinGW package, run CMake like this:
|
The exact file to use depends on the prefix used by the MinGW binaries on your
|
||||||
|
system. You can usually see this in the /usr directory, i.e. the Ubuntu
|
||||||
|
MinGW-w64 packages have /usr/x86_64-w64-mingw32 for the 64-bit compilers, so the
|
||||||
|
correct invocation would be:
|
||||||
|
|
||||||
cmake -DCMAKE_TOOLCHAIN_FILE=CMake/i586-mingw32msvc.cmake .
|
cmake -DCMAKE_TOOLCHAIN_FILE=CMake/x86_64-w64-mingw32.cmake .
