-tc
The
-tc
option instructs the compiler to generate
pc3
stab information that
allows cross-module type checking.
This option can be used for two purposes:
•
To check for any name conflicts that your program may have with the
standard libraries with which it is to be linked, such as
libc
. The linker
allows name conflicts, which may cause erroneous runtime behavior in your
program.
For example, the following program has a name conflict with
libc
:
When the program is compiled with the
-tc
option,
pc3
issues a warning
that the name
time
is already defined as a
libc
routine. Running
a.out
causes a core dump. To avoid this problem, change the name of the variable
that has the conflict—in this case,
time
.
•
To check for possible name conflicts in the various modules of your
program. These conflicts arise if you define a routine with the same name in
several modules, or refer to an external, but undefined, variable. The linker
detects these error situations and does not create the executable file.
–temp=
dir
The
–temp
option instructs
pc
to locate the temporary files that it creates
during compilation in the directory named dir. For example, the following
command puts the temporary files in the current directory.
hostname% pc -temp=. hello.p
If you do not specify a temporary directory,
pc
places the temporary files in
the
/tmp
directory.
program p(output);
var time: integer;
begin
writeln(wallclock);
end.
