Building Program

As described in previous Test Drive - Hello World section, to build a project is easy for all required settings and procedures have been defined in the "Makefile" of target's directory.

lib/	common application library
cgi/	cgi program for HTTP server
etmd/	etmd service. UDP locator.
siod/	TCP/UDP to serial converter
example/	program examples
cgidemo/	CGI examples

To build a project:

Change working directory to the project. (e.g. cd prj/app/cgi)

Build it by 'make'.

Dependency:

The lib/lib.c is a static link library which is used by all applications. If lib.c is changed, other projects should be rebuilt to update the changes.

CFLAGS: compiler option

-Wall

Enable most common warnings. This is the default settings in our projects.

-O2

Enable optimization. The optimization is not safe and some programs experienced problems. The project default is no optimization.

UCFLAGS: linker option

-Wl, -elf2flt

Convert ELF relocation format into FLAT format which is required for uClinux.
