== MaKL is a Prerequisite ==



LibU needs http://koanlogic.com/makl to configure and build. 



The following commands should be sufficient to get MaKL installed on any Linux 

flavour or Darwin/MacOSX:



$ wget http://koanlogic.com/download/makl/makl-${VERSION}.tar.gz

$ tar zxf makl-${VERSION}.tar.gz && cd makl-${VERSION}

$ sh configure.sh

$ su 

Password: ****

# make install



Should your platform be one of Solaris, OpenSolaris, FreeBSD, PC-BSD, OpenBSD,

NetBSD, DragonflyBSD, Minix or Windows (MinGW or Gygwin) take a look at the 

INSTALL file in the top-level MaKL sources directory to track down specific 

variations on the theme.



== Download == 



Once MaKL is there, you can start downloading the package (always check the 

official http://koanlogic.com/libu page for the latest version and related 

ChangeLog) and tailor it to your specific needs:



$ wget http://koanlogic.com/download/libu/libu-${VERSION}.tar.gz

$ tar zxf libu-${VERSION}.tar.gz && cd libu-${VERSION}



== Configure ==



E.g. should you need to change the default installation path (i.e. /usr/local),

use:



$ makl-conf --prefix="/my/install/base/dir"



Debug symbols and warnings from the compiler can be switched on via

--enable_debug and --enable_warns (use --enable_icc_warns instead when 

working with the Intel C compiler):



$ makl-conf --enable_debug --enable_warns



Code profiling using gprof(1) can be activated via --enable_profile, and,

more generally, any compiler flag can be passed to the build stage in the 

following way:



$ makl-conf --extra-cflags="-Wformat -Wno-format-extra-args -Wformat-security -Wformat-nonliteral -Wformat=2"



The --extra-xxx="val" is indeed a powerful mechanism by which any Makefile 

variable 'XXX' (uppercase!) can be given an additional value 'val': (ab)use 

it to tweak LDFLAGS, SHLIB_LDFLAGS, etc. as needed.  Anyway if in doubt, 

or in search for exotic features, type makl-conf -h to display the complete 

list of options: it's likely that what you are trying to achieve is already 

there.



By default LibU is compiled as static library, to also enable shared library 

build, supply the --enable_shared flag.



== Pick Up What Needs to be Included ==



The default is to build all the modules, but you can disable the 

inclusion of specific bits selectively using the following switches:

    - --no_hmap: to disable the hmap module

    - --no_config: to disable the config module

    - --no_net: to disable the net module

    - --no_env: to disable the env module

    - --no_fs: to disable the fs module

    - --no_pwd: to disable the pwd module

    - --no_list: to disable the list module

    - --no_array: to disable the array module

    - --no_ringbuffer: to disable the rb module

    - --no_pqueue: to disable the pq module

    - --no_json: to disable the json module

    - --no_bst: to disable the bst module



Also, some specific features regarding the networking code can be disabled

at configuration:

    - --no_ipv6: to disable IPv6 protocol support

    - --no_sctp: to disable SCTP protocol support

    - --no_unixsock: to disable UNIX IPC support



If you need to enable compatibility with (some, not all) 1.X interfaces, 

specify the --compat_1x command line switch.



== Build, Test and Install ==



When you are done with the configure step, you can build LibU bits and 

optionally test them:



$ makl

$ makl -C test



And finally install it:



$ su

Password: ****

# makl install



== Hello LibU ! ==



You now are ready to play with your first LibU program:



$ cat main.c

#include 



int facility = LOG_LOCAL0;



int main (void)

{

    u_con("Hello LibU world !");

    return 0;

}



Write a Makefile like the following:



$ cat Makefile

include common.mk



PROG = hellolibu

SRCS = main.c



LDADD += /path/to/install/prefix/lib/libu.a

CFLAGS += -I/path/to/install/prefix/include



include prog.mk



Then type:



$ makl && ./hellolibu



and enjoy !
