Hi,
I'm trying to cross-compile libftdi-1.1 with the MXE toolchain
(http://mxe.cc/, uses mingw32) and ran across two issues:
Cmake cannot find gettext() as it's in a separate library and not part
of libc. There's a TODO in the corresponding .cmake file
(cmake/FindLibintl.cmake) for this case but unfortunately I know nothing
of cmake to fix this properly. The following hack works though:
--- a/cmake/FindLibintl.cmake
+++ b/cmake/FindLibintl.cmake
@@ -34,6 +34,7 @@
else (LIBINTL_LIBC_HAS_DGETTEXT)
find_library(LIBINTL_LIBRARIES NAMES intl libintl )
if(LIBINTL_LIBRARIES)
+ set(LIBINTL_LIBRARIES "-lintl -liconv")
set(LIBINTL_LIB_FOUND TRUE)
endif(LIBINTL_LIBRARIES)
endif (LIBINTL_LIBC_HAS_DGETTEXT)
The other thing is that I didn't manage to compile the tests due to some
weird undefined references to boost_test:

I tried tracking this down but got nowhere. The only way I got libftdi
to compile was to disable the tests completely by removing
test/CMakeLists.txt.
Some additional information about my environment:
$ i686-pc-mingw32-gcc --version
i686-pc-mingw32-gcc (GCC) 4.8.1
Boost Version: 1.53.0
libusb: 1.0.18
libconfuse: 2.7
Cheers,
Sam
