# CMake Toolchain file for cross compiling OpenSCAD tests linux->mingw-win32
|
|
# --------------------------------------------------------------------------
|
|
#
|
|
# Prerequisites: mingw-cross-env, ImageMagick 6.5.9.3 or newer, wine
|
|
#
|
|
# Usage:
|
|
#
|
|
# - follow Brad Pitcher's mingw-cross-env for OpenSCAD setup:
|
|
# http://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Cross-compiling_for_Windows_on_Linux_or_Mac_OS_X
|
|
# - cross-compile openscad.exe, to verify your installation works properly.
|
|
# - cd openscad/tests && mkdir build-mingw32 && cd build-mingw32
|
|
# - cmake .. -DCMAKE_TOOLCHAIN_FILE=CMingw-cross-env.cmake \
|
|
# -DMINGW_CROSS_ENV_DIR=<where mingw-cross-env is installed>
|
|
# - make should proceed as normal.
|
|
# - now run 'ctest' on your *nix machine.
|
|
# The test .exe programs should run under Wine.
