Just getting started with C++ here. I am working on OSX with Eclipse CDT. I have a project with some custom classes and two files “Test.hpp” and “Test.cpp” – the later with my main() method that runs some tests that I have defined and implemented in these two files.
I can compile and run from Eclipse with no problems, but when I try to compile from the command line with “g++ Test.cpp” I get a lot of linking errors that basically list all the methods defined in or referenced from Test.cpp as undefined symbols.
I have compiled a few basic programs (one header file and one implementation file) in similar manner from the command line without any problems, but I can’t figure out why this one won’t work. Please help!
EDIT: It wasn’t clear from my wording, but yes I have other source files too. The accepted answer did the trick: “g++ Test.cpp Other1.cpp Other2.cpp”. Thank you.
Command ‘g++ Test.cpp’ does both compilation and linking. If you have many source files, you should link Test.cpp with them too like ‘g++ Test.cpp other1.cpp other2.cpp’ or just compile all files and link them all together later like ‘g++ Test.o other1.o other2.o’.
