Sun Studio 12 Update 1: Fortran User's Guide

2.2.1 Compile-Link Sequence

In the previous example, the compiler automatically generates the loader object files, growth.o and fft.o, and then invokes the system linker to create the executable program file growth.

After compilation, the object files, growth.o and fft.o, will remain. This convention permits easy relinking and recompilation of files.

If the compilation fails, you will receive a message for each error. No .o files are generated for those source files with errors, and no executable program file is written.
