ok, you've caught me cheating a bit. :-) I've got those too but worked around
them by commenting out the affected lines of code in plugin.cpp and
genbankformat.cpp since I don't need them at the moment. After doing that I ran
into the problems I've already mentioned.
The next thing I've tried is to change this code in src/formats/CMakeLists.txt:
set(ADD_INCHI_FORMAT FALSE)
if(WITH_INCHI)
if(NOT OPENBABEL_USE_SYSTEM_INCHI)
set(ADD_INCHI_FORMAT TRUE)
else()
if (EXISTS ${INCHI_LIBRARY})
set(ADD_INCHI_FORMAT TRUE)
else (EXISTS ${INCHI_LIBRARY})
message("WARNING: INCHI_LIBRARY not set, or does not exist.\n....InChI
format will NOT be compiled.")
endif()
endif()
endif()
if(ADD_INCHI_FORMAT)
add_definitions(-DINCHI_LINK_AS_DLL)
if(NOT OPENBABEL_USE_SYSTEM_INCHI)
add_subdirectory(inchi103)
include_directories(${CMAKE_SOURCE_DIR}/include/inchi103)
set(libs ${libs} inchi)
else()
include_directories(${INCHI_INCLUDE_DIR})
set(libs ${libs} ${INCHI_LIBRARY})
endif()
set(inchiformat_additional_sources getinchi.cpp ../ops/unique.cpp)
set(formats_common
${formats_common}
inchiformat
)
endif()
which, if I understand it correctly, should include the /inchi103 subdirectory
and the neccessary include files into the compilation and add 'inchiformat' to
the list of supported formats.
But even when I change it to:
add_definitions(-DINCHI_LINK_AS_DLL) //Is this needed for static linking as
well?
add_subdirectory(inchi103)
include_directories(${CMAKE_SOURCE_DIR}/include/inchi103)
set(libs ${libs} inchi)
set(formats_common
${formats_common}
inchiformat
)
which should force inclusion of inchiformat regardless of any environment
variables set, the linking errors persist.
Best regards,
Ernst-Georg
