NAME¶
klcc - compile a program against klibc
SYNOPSIS¶
klcc [
gcc options] [
-o outfile]
infile...
DESCRIPTION¶
klcc is a wrapper around
gcc(1) and
ld(1) which compiles
and links a program against the
klibc tiny C library. It supports most
gcc options.
Unlike
gcc,
klcc compiles with optimization on by default.
Furthermore, the optimization level used depends on whether or not
-g
is specified, since
klcc frequently uses options in the normal case
which makes debugging impossible. Therefore, compile without
-g,
-O,
-f or
-m option to use the default optimization
level; this will generally result in the smallest binaries. You may want to
use
-s when linking, however. Use
-O0 to compile without any
optimization whatsoever; this may not work depending on the version of
gcc used.
- -nostdinc
- allows to turn off klibc include files.
Use the
-shared or
-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.
In addition to standard
gcc options,
klcc supports options of the
form
-print-klibc-option, which prints the corresponding klibc
configuration option.
