Most UNIX compilers also do not generate source code listings. UNIX utility programs are used to insert compiler error messages directly into the source file as comments. This can allow easy correction of errors while editing the source file. The UNIX filter programs can then be used to quickly strip the error comments from the source code. Creating multiple windows on the workstation also allows easy viewing of errors and source code simultaneously.
Some examples follow.
Compile the source file graph.c . Link to the object file plot.o and the library gl. Produce the executable named graph . Only compile the source file. Pipe the stderr output into the program error.
