QFCC(1) QuakeForge Developer's Manual QFCC(1)NAMEqfcc - The QuakeForge Code Compiler
SYNOPSISqfcc [options] [files]
DESCRIPTIONqfcc compiles Ruamoko source into a form that the QuakeForge engine can
understand.
OPTIONSqfcc takes the following arguments:
--traditional
Use traditional QuakeC syntax, semantics and “bugs”. Also
implies the v6only code generation option. This is the default
when using progs.src.
--advanced
Use advanced Raumoko features. This is the default when using
separate compilation.
-C, --code OPTION,...
Set code generation options. See CODE GENERATION OPTIONS for
details.
-c Compile only, do not link. Can be used in either progs.src or
separate compilation modes.
-D, --define SYMBOL[=VAL]
Define a symbol for the preprocessor, if it is in use.
-F, --files
Generate files.dat. This list is created by checking the parame‐
ters to the precache_* functions.
-g Generate debugging info. Synonym for --code debug.
-h, --help
Show summary of options.
-I DIR Add DIR to the list of directories for the preprocessor to
search when looking for include files.
--include FILE
Process FILE as if #include "FILE" appeared as the first line of
the primary source file. See the cpp man page (-include) for
details.
-L DIR Add DIR to the search path used for -l.
-l LIB Add libLIB.a to the list of libraries to be used for resolving
undefined symbols. qfcc's libraries are really pak files of qfcc
object files built using the pak utility.
-N, --notice OPTION,...
Set notice options. See NOTICE OPTIONS for details.
-o, --output-file FILE
Specify output file name.
-P, --progs-src FILE
File to use instead of progs.src
-p, --strip-path NUM
Strip NUM leading path elements from file names. eg. -p 3 will
strip the output code.
-q, --quiet
Inhibit some of qfcc's normal output.
-r Incremental linking. Generate a larger object file from other
object files and libraries.
-S, --save-temps
Do not delete temporary files.
-s, --source DIR
look for progs.src in DIR instead of the current directory.
-U, --undefine SYMBOL
Undefine a preprocessor symbol, if the preprocessor is in use.
-V, --version
Show the version of qfcc.
-v, --verbose
Display more output than usual.
-W, --warn OPTION,...
Set warning options. See WARNING OPTIONS for details.
-z Compress object files when writing them. This is especially use‐
ful when creating libraries, especially if using the object ori‐
ented features, but can be quite slow.
--cpp CPPSPEC
cpp execution command line. See CPP NAME for details.
CODE GENERATION OPTIONS
Code generation options are processed in the order of their appearance
on the command line. Unsupported options are ignored. The following
options are supported by qfcc's --code argument:
cow Allow assignment to initialized globals. In Quake-C and Ruamoko,
a global that has been initialized to a value is not a variable,
but a named constant. However, qcc never really enforced this.
The cow option allows qfcc to gracefully cope with QuakeC source
that assigns values to initialized globals in this manner. (also
known as “copy on write”—never mind the bovine connotations)
debug Generate debug code for QuakeForge engines. The QuakeForge
engine has the ability to load line number and other debugging
information for use in diagnosing progs crashes. This option
tells qfcc to generate this information. It is written to a sec‐
ondary file with the extension “sym”—if your output file is
“progs.dat”, the symbol file will be “progs.sym”.
short-circuit
Generate short circuit code for logical operators (&& and ||).
For A && B, if A is false, the expression is known to be false
and the code for B will not be executed. Similar for A || B, but
if A is true, the expression is known to be true and the code
for B will not be executed. Defaults to off for traditional
mode, and on for advanced mode.
fast-float
Use float values directly in “if” statements. Defaults to on.
This option is always enabled when using version 6 progs.
v6only Restrict the compiler to only version 6 progs (original
Quake/QuakeWorld) features. This means that the compiled data
file should be able to run on older servers, as long as you have
not used any QuakeForge-specific built-in functions. Also dis‐
ables some of the compiler's features (like integers and string
manipulation support).
WARNING OPTIONS
Warning options are processed in the order of their appearance on the
command line. Unsupported options are ignored. The following options
are supported by qfcc's --warn argument:
cow Emit a warning when the source assigns a value to a named con‐
stant. See the description of the cow code option above for a
description of what this means.
interface-check
Emit a warning when a method is declared in an implementation
but not in the interface for a class.
undef-function
Emit a warning when a function is called, but has not yet been
defined.
uninited-var
Emit a warning when a variable is read from that has not been
initalized to a value.
vararg-integer
Emit a warning when a function that takes a variable number of
arguments is passed a constant of an integer type.
error Promote warnings to errors.
Any of the above can be prefixed with no- to negate its meaning. There
are also two special options:
all Turns on all warning options except error.
none Turns off all warning options except error.
NOTICE OPTIONS
Notices are used to flag code constructs that may have changed seman‐
tics but shouldn't be treated as warnings. They are also used for
internal debugging purposes, so if you see any cryptic notices, please
report them as a bug (normal notices should be fairly self-explana‐
tory).
none Silences all notice messages.
warn Promote notices to warnings. If warnings are being treated as
errors, so will notices.
CPP NAME
When preprocessing source files, qfcc calls cpp (the C preprocessor)
with a configurable command line. This is useful when you wish to use
an alternative preprocessor (though it must be command line compatible
with cpp) or when qfcc has been misconfigured to call cpp incorrectly
for your operating system. If the latter is the case, please report the
details (operating system, detection methods, correct execution speci‐
fication). The base default execution spec (on most Linux systems) is
cpp %d -o %o %i. This spec is similar in concept to a printf string.
The name of the program may be either absolute (eg /lib/cpp) or rela‐
tive as the PATH will be searched. Available substitutions:
%d Mainly for defines (-D, -U and -I) but %d will be replaced by
all cpp options that qfcc will be passing.
%o This will be replaced by the output file path. Could be either
absolute or relative, depending on whether qfcc is deleting tem‐
porary files or not.
%i This will be replaced by the input file path. Generally as given
to qfcc.
FAQ
Where did the name Ruamoko come from?
In Maori mythology, Ruamoko is the youngest child of Ranginui,
the Sky-father, and Papatuanuku, the Earth-mother. Ruamoko is
the god of volcanoes and earthquakes (Quake, get it?). For more
information, see the Web site at <http://maori.com/kmst1.htm>.
qfcc is singing a bad 80s rap song to me. What's going on?
“ice ice baby” is QuakeForge-speak for “Internal Compiler
Error”. It usually means there's a bug in qfcc, so please report
it to the team.
qfcc is mooing at me. What's wrong with you people?
The compiler doesn't like being treated like a slab of beef.
Seriously, the code you are trying to compile is using constants
as if they weren't. Normally, qfcc would just stop and tell the
code to sit in the corner for a while, but you told it not to do
that by passing the cow option to --code, so it has its revenge
by mooing out a warning. Or something like that. To disable the
warning, pass no-cow to --warn.

The original qcc program, for compiling the QuakeC language, was writ‐
ten by Id Software, Inc. The members of the QuakeForge Project have
modified it to work with a new, but very similar language called
Ruamoko.
