The compile command is the SmartEiffel compiler. There are
two invocation modes: traditional and ACE. In
traditional mode, a
variety of compiler options can be specified on the command line. In
ACE mode, these options are not permitted; it is presumed that the
required compiler options are listed in the ACE file.
se c [general_options] [compile_to_c_options]
se c [general_options] <ACEfile.ace>
In ACE mode, the name of the ACE file must end with the .ace
suffix. For examples of how to use ACE files, have a look in the
Source code is in Eiffel and target code is in ANSI C.
The compile command executes in two major steps:
Step 1 -||the
compile_to_c command is called to produce various
C files (*.h and *.c). A script file is also produced
by compile_to_c. The name of the script file
is also printed by compile_to_c (*.make on
Unix or *.BAT on DOS, for example).
Step 2 -||The script file produced during
step 1 is run, launching the C compilation(s) and linking of
all the C files produced during the previous step.
Thus, the compile command is a simple launcher used to
call the compile_to_c command,
the C compiler, and the linker in sequence.
Like the compile_to_c command, the compile command must have at least
one argument to indicate the starting execution point of the system.
Thus execution will start in <RootProcedure> of <RootClass>.
The default <RootProcedure> is make.
- By default, the generated C files and object files are retained from one invocation
of the compile command
to another. This enables incremental C compilation, since only the
C files which have been modified since the last invocation of
the compile command will be recompiled. Because the Eiffel
to C compilation performed by SmartEiffel is generally much faster
than the C compilation itself, incremental C compilation saves time.
However, there are situations where you want to get rid of all
the previously generated C and object files, to start afresh.
The -clean option removes the C files, object files and some other
previously generated files, by
invoking the clean command at the end of the compilation.

|Examples of Traditional Mode
When SmartEiffel is correctly installed, you can type
the following command to test the "hello world" program:
The compiler should tell you what's wrong or should compile
Eiffel source files telling you the full path used to load
the Eiffel source code.
se c hello_world
Under UNIX, the executable file is named "a.out" by default.
Type the following command to finalise the hello_world simple
Note that the -O3 option is passed to the C compiler (see the manual
of your C compiler). The -boost and -no_split options
are passed to the
se c -boost -no_split -O3 hello_world
This is usually the best way to finalise your application.
Only one C file is produced (option -no_split).
To compile a big project (class PROJECT) with C file splitting and
require assertions checked:
The very first time, all C files are produced and compiled.
Then, if you type the same command after some changes in the
Eiffel source files, all C files are also produced from scratch.
If there are only minor changes in the generated
C files, only modified ones are passed to the C compiler
(previous object files have been saved).
