So, I think I have gotten it working. First of all, I had the same problem
as you with the macro_ensure_version string. For the moment I just replaced
those lines in CMakeLists.txt with:
set(GCC_IS_NEWER_THAN_4_0 TRUE)
set(GCC_IS_NEWER_THAN_4_1 TRUE)
set(GCC_IS_NEWER_THAN_4_2 TRUE)
I also had some problem at the link stage with InChI, so I just turned that
off (-DWITH_INCHI=FALSE).
In src/dlhandler_win32.cpp, after the lines:
if(!handle)
handle = GetModuleHandle("openbabel-2.dll");//CMake/VC++2008 build will
use this.
...I added:
if (!handle)
handle = GetModuleHandle("libopenbabel.dll"); // MinGW
And finally, in src/CMakeLists.txt I changed MSVC to WIN32 in one section
as follows:
if(BUILD_SHARED)
if(WIN32)
set(openbabel_srcs ${openbabel_srcs}
dlhandler_win32.cpp
)
else(WIN32)
set(openbabel_srcs ${openbabel_srcs}
dlhandler_unix.cpp
)
endif(WIN32)
else(BUILD_SHARED)
If you can check/confirm that this makes things work for you, then I look
into making these changes permanent and setting up an automated build.
Regards,
- Noel
