Three commands that compile the files main.cpp, type1.cpp, and type2.cpp separately are g++ -c main.cpp g++ -c type1.cpp g++ -c type2.cpp Executing these three commands creates the files main.o, type1.o, and http://softacoustik.com/linker-error/linker-error-in-c-tv-lib.php

Aside: Even virtual memory has limits. The main program in main.cpp uses a class called Type1, declared in the file type1.h-no executable code appears here-and defined, with executable code, in the file type1.cpp. These can often be more frustrating because they aren't necessarily the result of something written in your program. int main () { Type1 xyz; ...
