Thank you for your response, I use the development code,and the svn version is 4528, The compilation and the installation work fine. However, the compilation of Mychem fails with the following error: [ 3%] Building C object src/CMakeFiles/mychem-lib.dir/conversion.c.o [ 7%] Building CXX object src/CMakeFiles/mychem-lib.dir/conversion_wrapper.cpp.o [ 11%] Building C object src/CMakeFiles/mychem-lib.dir/helper.c.o [ 14%] Building CXX object src/CMakeFiles/mychem-lib.dir/helper_wrapper.cpp.o [ 18%] Building C object src/CMakeFiles/mychem-lib.dir/modification.c.o [ 22%] Building CXX object src/CMakeFiles/mychem-lib.dir/modification_wrapper.cpp.o [ 25%] Building C object src/CMakeFiles/mychem-lib.dir/molmatch.c.o [ 29%] Building CXX object src/CMakeFiles/mychem-lib.dir/molmatch_wrapper.cpp.o [ 33%] Building C object src/CMakeFiles/mychem-lib.dir/property.c.o [ 37%] Building CXX object src/CMakeFiles/mychem-lib.dir/property_wrapper.cpp.o [ 40%] Building CXX object src/CMakeFiles/mychem-lib.dir/serialization.cpp.o [ 44%] Building CXX object src/CMakeFiles/mychem-lib.dir/dlhandler_unix.cpp.o Linking CXX shared library libmychem.so CMakeFiles/mychem-lib.dir/property_wrapper.cpp.o: In function `OBGroupContrib': /usr/local/include/openbabel-2.0/openbabel/groupcontrib.h:56: undefined reference to `vtable for OpenBabel::OBGroupContrib' /usr/local/include/openbabel-2.0/openbabel/groupcontrib.h:56: undefined reference to `vtable for OpenBabel::OBGroupContrib' /usr/local/include/openbabel-2.0/openbabel/groupcontrib.h:56: undefined reference to `vtable for OpenBabel::OBGroupContrib' CMakeFiles/mychem-lib.dir/property_wrapper.cpp.o: In function `~OBGroupContrib': /usr/local/include/openbabel-2.0/openbabel/groupcontrib.h:46: undefined reference to `vtable for OpenBabel::OBGroupContrib' collect2: ld returned 1 exit status make[2]: *** [src/libmychem.so.0.8.2] 错误 1 make[1]: *** [src/CMakeFiles/mychem-lib.dir/all] 错误 2 make: *** [all] 错误 2
