.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.
|
|
.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.
