linked list troubles

[MBattiston]

hello

my name is michael

im having some trouble with the add_node functino in my linked list

these are the files i have
node.h, node.cpp, linkedList.h, linkedList.cpp

linkedList.cpp is where the problem is
everytime i try to compile it (using Cygwin) it says:

"undefined reference to node::set_data(char& const)"

and

"undefined reference to node::set_link(node*)"

i have no idea what this means.
if you could help me understand where i went wrong it would be much appreciated.

also, if you need to see my node class or linked list class i can show you.

regards
Mike

You didn't include the .cpps in the project or command line.
Basically, the linker is saying "ok, I have this function named such and such, but I don't have code to jump to if something was to call said function."

[MBattiston]

yeah i did that
it still comes up with the error

i did g++ -o node.h node.h
then g++ -o node.cpp node.cpp

and the same for linkedList class

any suggestions?

[helios]

Yeah. That's not how it's done:
g++ node.cpp linkedList.cpp


Usage: g++.exe [options] file...
Options:
-pass-exit-codes Exit with highest error code from a phase
--help Display this information
--target-help Display target specific command line options
(Use '-v --help' to display command line options of sub-processes)
-dumpspecs Display all of the built in spec strings
-dumpversion Display the version of the compiler
-dumpmachine Display the compiler's target processor
-print-search-dirs Display the directories in the compiler's search path
-print-libgcc-file-name Display the name of the compiler's companion library
-print-file-name=<lib> Display the full path to library <lib>
-print-prog-name=<prog> Display the full path to compiler component <prog>
-print-multi-directory Display the root directory for versions of libgcc
-print-multi-lib Display the mapping between command line options and
multiple library search directories
-print-multi-os-directory Display the relative path to OS libraries
-Wa,<options> Pass comma-separated <options> on to the assembler
-Wp,<options> Pass comma-separated <options> on to the preprocessor
-Wl,<options> Pass comma-separated <options> on to the linker
-Xassembler <arg> Pass <arg> on to the assembler
-Xpreprocessor <arg> Pass <arg> on to the preprocessor
-Xlinker <arg> Pass <arg> on to the linker
-save-temps Do not delete intermediate files
-pipe Use pipes rather than intermediate files
-time Time the execution of each subprocess
-specs=<file> Override built-in specs with the contents of <file>
-std=<standard> Assume that the input sources are for <standard>
-B <directory> Add <directory> to the compiler's search paths
-b <machine> Run gcc for target <machine>, if installed
-V <version> Run gcc version number <version>, if installed
-v Display the programs invoked by the compiler
-### Like -v but options quoted and commands not executed
-E Preprocess only; do not compile, assemble or link
-S Compile only; do not assemble or link
-c Compile and assemble, but do not link
-o <file> Place the output into <file>
-x <language> Specify the language of the following input files
Permissible languages include: c c++ assembler none
'none' means revert to the default behavior of
guessing the language based on the file's extension

Options starting with -g, -f, -m, -O, -W, or --param are automatically
passed on to the various sub-processes invoked by g++.exe. In order to pass
other options on to these processes the -W<letter> options must be used.

<URL:http://www.mingw.org/bugs.shtml>.

-o specifies what the executable will be named.

I do wonder what must have gone through your mind to make you put the same file name twice.
