"undefined reference to" error

Slowly, ever so slowly, I'm trying to learn C++. I have this Big Fat Book on my desk and almost every day I read, tinker, and study code. While trying to compile koffice I ran into these fatal errors: ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::~Parser()' ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::statement() const' ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::parse(QString const&)' ../../.libs/libkexidb.so: undefined reference to `tname(int)' ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::Parser(KexiDB::Connection*)' ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::query()' If the g++ error lists a line in a *.cpp file, then usually the "undefined reference to" error means a missing header file that declares the namespace or function. In this particular error, g++ listed a static library. From what I've read, this means something is awry in the linking process and not in the code itself. Am I on the right track? If not then please set me straight. :) If yes, then how do I fix the error? I presume something in the Makefiles? Does the error provide me clues as to where I need to fix the problem? Trying to learn! Thanks! Darrell
