.TH klcc "1" "1 March 2005" "klibc" "H. Peter Anvin"
.SH NAME
klcc \- compile a program against klibc
.SH SYNOPSIS
.B klcc
[\fIgcc options\fP]
[\fB\-o\fP \fIoutfile\fP]
\fIinfile...\fP
.SH DESCRIPTION
.PP
.B klcc
is a wrapper around
.BR gcc (1)
and
.BR ld (1)
which compiles and links a program against the
.B klibc
tiny C library.  It supports most
.B gcc
options.
.PP
Unlike
.BR gcc ,
.B klcc
compiles with optimization on by default.  Furthermore, the
optimization level used depends on whether or not
.B \-g
is specified, since
.B klcc
frequently uses options in the normal case which makes debugging
impossible.  Therefore, compile without
.BR \-g ,
.BR \-O ,
.B \-f
or
.B \-m
option to use the default optimization level; this will generally
result in the smallest binaries.  You may want to use
.B \-s
when linking, however.  Use
.B \-O0
to compile without any optimization whatsoever; this may not work depending
on the version of
.B gcc
used.
.TP
.B \-nostdinc
allows to turn off klibc include files.
.PP
Use the
.B \-shared
or
.B \-static
option to compile for and link against shared or static klibc.  Note
that shared klibc only supports running against the exact same klibc
binary as the binary was linked with.
.PP
In addition to standard
.B gcc
options,
.B klcc
supports options of the form \fB\-print-klibc-\fP\fIoption\fP,
which prints the corresponding klibc configuration option.
