Re: [opensuse] Linking problem with g++ [off topic]



Thank you for your answers. I have used some inline functions, but it
seems that the compiler does not support inline functions implemented
elsewhere than in the header file.

Sorry to use this list for my problem, but I really need a quick answer

I have defined a class into two files XP_class.h and XP_class.cpp
and use the header XP_class.h into another file xml_parser.cpp to
create an object in the main function. However, when compiling and
linking all the
files, I get the following error:

g++ `xml2-config --cflags` xml_parser.cpp XP_class.cpp `xml2-config --
libs` -o xml_parser
/tmp/ccX1d5Hj.o: In function `main':
xml_parser.cpp:(.text+0x195): undefined reference to `XP::XP()'
xml_parser.cpp:(.text+0x1a8): undefined reference to
`XP::init_DOM(char const*)'
xml_parser.cpp:(.text+0x1c2): undefined reference to `XP::~XP()'
xml_parser.cpp:(.text+0x229): undefined reference to
`XP::get_value(char const*)'
xml_parser.cpp:(.text+0x2b7): undefined reference to `XP::~XP()'
collect2: ld returned 1 exit status

I know that it must be some simple mistake, but I was not been able to
figure out what it is. I would appreciate your help.



Look for an error which is syntactically legal, but
semantically wrong (say like, a forgotten } character),
which would make your XP object definition be inside
another function.

C and C++ are notorious for indicating certain types
of errors after the line on which the actual mistake
is located.
