Hi,
I have a project that builds fine both on Linux and on mingw32 using
cmake version 2.6-patch 2.
Now, I am trying to cross compile my project on a Linux (Ubuntu 9.04)
machine for the target Windows platform using the mingw32 cross
compiler. I have a toolchain more or less copied from
http://www.itk.org/Wiki/CmakeMingw that looks like this:
# the name of the target operating system
SET(CMAKE_SYSTEM_NAME Windows)
# which compilers to use for C and C++
SET(CMAKE_C_COMPILER i586-mingw32msvc-gcc)
SET(CMAKE_CXX_COMPILER i586-mingw32msvc-g++)
# here is the target environment located
SET(CMAKE_FIND_ROOT_PATH /usr/i586-mingw32msvc )
# adjust the default behaviour of the FIND_XXX() commands:
# search headers and libraries in the target environment, search
# programs in the host environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
My problem is that running
cmake -DCMAKE_TOOLCHAIN_FILE=Toolchain-mingw32.cmake
I get the error:
CMake Error at /usr/share/cmake-2.6/Modules/FindSWIG.cmake:55 (MESSAGE):
SWIG was not found. Please specify Swig executable location
If I remove the last line in the toolchain file, cmake finds swig, but I
get other include-related errors.
Swig is run on the host platform to generate code, so shouldn't its
configuration be independent of the target platform?
Any help?
Thank you!
Giampiero
