== 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 <u/libu.h> 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 !
