Hi,

I'm trying to compile the example code on this page:

http://openbabel.org/wiki/Developer:Cpp_Tutorial

but I get errors during compilation with this command (the header files
are installed in /home/sam/progs/openbabel-2.2.3/include):

g++ -I/home/sam/progs/openbabel-2.2.3/include convert.cpp -o convert

/tmp/ccbdQkQz.o: In function `main':
convert.cpp:(.text+0x19c): undefined reference to 
`OpenBabel::OBConversion::OBConversion(std::basic_istream<char, 
std::char_traits<char> >*, std::basic_ostream<char, std::char_traits<char> >*)'
convert.cpp:(.text+0x1ba): undefined reference to 
`OpenBabel::OBConversion::SetInAndOutFormats(char const*, char const*)'
convert.cpp:(.text+0x1ff): undefined reference to 
`OpenBabel::OBConversion::Convert()'
convert.cpp:(.text+0x25d): undefined reference to 
`OpenBabel::OBConversion::~OBConversion()'
convert.cpp:(.text+0x279): undefined reference to 
`OpenBabel::OBConversion::~OBConversion()'
collect2: ld returned 1 exit status

The openbabel-2.2.3 source was manually compiled on ubuntu 9.04.

Please can anybody help?

Thanks,
Sam
