Introduction This document details configuring, compiling, and installing LessTif on various platforms. Readers that have (or are interested in) a binary version of LessTif can jump to section 6.2 immediately. It also explains where to get the binary (pre-compiled) versions of LessTif. If you have any corrections/additions/comments about this document, please send E-mail to LessTif@LessTif.org . 2. Before LessTif (Compiling it) Lesstif is meant as a source compatible replacement/alternative to Motif 1.2. As such, it will have the same requirements as Motif 1.2. As far as we know, the only requirement that Motif 1.2 has is that you have X11R5 on your system. Lesstif will _not_ compile with R4 or earlier. If you have X11R5 or above, you should be able to compile and run LessTif programs. What this means is that all you folks out there with Suns running SunOS 4.x that haven't uprgraded your X11 release to R5 -- don't use /usr/openwin. That's R4 stuff, and won't work with LessTif. Please don't send bug reports about this, because there is no way we can write LessTif and remain source compatible with R4 or earlier. If you're going to be doing development work with LessTif, building the dependencies for the library files is a necessity. You must have 'makedepend' to do this. This should be standard on any machine with R5, but if you can't find it, get it from ftp.x.org (try in /pub/R6untarred). If you don't have makedepend in your path, `make depend' will not work. Lastly, you will need an ANSI-C compiler to build Lesstif. If you have GNU CC, you're set. 3.

Configuring LessTif Configuration of LessTif is now handled by GNU Automake, GNU Libtool, and GNU Autoconf. [Historical note: at one time, there was an Imakefile package contributed by Paul Hoad; this package was not maintained, and has been removed.] Automake, libtool, and autoconf are tools which the LessTif developers use to generate the distribution's build scripts and makefiles. Normally this shouldn't bother you. The end result is that there are a bunch of Makefile.in files, and a "configure" script. Configure is a script which is meant to be run by people who compile LessTif (you, probably). It looks at your system and figures out how exactly to compile. It may need a little help through command-line options, see below. To configure LessTif for your system, just type 'configure'. This should do a reasonable job of locating the stuff it needs, and gives rather verbose output should something fail. Two things that configure looks for on your machine are: - X11R5/R6/R6.1 headers and libaries - Motif 1.2 headers and libraries (optional) Now many people who have Motif on their system don't use LessTif. Hmm. Wonder why that is. Anyway, it wouldn't make much sense if you needed Motif in order to build LessTif. The good news is : you don't need it. The only reason why you can tell configure where to find Motif stuff is so it can configure the Makefiles under test/ to be capable of building LessTif as well as Motif tests. Configure will tell you where it has found them if it found them. If it didn't find X, you'll have to specify the path on configure's command line. Use these two options: --x-includes --x-libraries And to specify the Motif stuff, use these: --with-motif-includes --with-motif-libraries To specify the location of the various bits, you have to set these flags equal to something. An example on how to do this is: configure --x-includes=/usr/local/X11R5/include The other flags behave identically. NOTE: On an HP/UX system that we have access to, the command line that we used to configure LessTif is : CC="cc -Ae" configure --disable-static --x-includes=/usr/include/X11R6 --x-libraries=/usr/lib/X11R6 There are also other flags available on the command line. Each of these can take on either a 'yes' or 'no' value. They are: --enable-shared build shared libraries [default=yes] --enable-static build static libraries [default=no] --enable-build-12 build Motif-1.2 compatible version (default) --enable-build-20 build Motif-2.0 compatible version --enable-build-21 build Motif-2.1 compatible version --enable-build-CDE build Motif-CDE compatible version --with-dmalloc use dmalloc (ftp.letters.com) --enable-maintainer-mode enable make rules and dependencies not useful (and sometimes confusing) to the casual installer --enable-debug build LessTif with debugging options (-g)(default) --enable-verbose configure LessTif to be verbose (default) --enable-nonstandard-conversions include nonstandard conversions --enable-production build a production version (doesn't include XdbDebug calls which print all kinds of debugging info depending on some environment variables) --prefix=XXX tell configure where LessTif should be installed. You can type configure --help to get the list of all options, with a short description of each. 5. Compiling LessTif After configuring LessTif, just typing 'make' should build all the libraries, clients, and (optionally) tests for LessTif. To build libraries or other things only, just cd to the directory in which you want to build things, and type 'make'. Dependencies have been set up so that the libraries will be recompiled if they are old (or haven't been compiled yet), so typing make from within a test directory will rebuild what needs to be rebuilt. Some combinations of compilers and libraries may have code generation bugs. For example, gcc-2.7.0 on a Solaris platform has known problems if the library is compiled with an optimization greater than -O (-O1). If you see weird problems when you debug library code, try a lower (or no) optimization. For the vast majority who compile with the default flags (-g for GNU-C), this is not an issue. 6. Installing LessTif 6.1 LessTif built from source Installing LessTif is as easy as typing 'make install'. Getting shared libraries to work on your machine after installation depends on your OS. Fortunately we're using GNU libtool to solve the platform-dependencies problems for us. 6.2 Binary distributions of LessTif Binary versions of LessTif are built and made available as a service to people who want to use LessTif without having to compile it themselves. As we're concentrating on developping and improving LessTif itself, we consider binary releases to be a side product, which we only generate once in a while - generally at each minor release. Our release policy is detailed in RELEASE-POLICY. Binary versions currently exist for Linux, FreeBSD, OS/2. 6.2.1 Where to get them The primary source for LessTif (ftp.lesstif.org, in /pub/hungry/lesstif) contains three different things : - source distributions (and a daily snapshot of CVS called lesstif-current) - daily diffs of the sources - binary distributions. 6.2.2 FreeBSD Starting with the 0.80a (0.80 pre-release), the FreeBSD binary distribution is provided as a pkg_add installable file. Pkg_add(8) is FreeBSD's installation tool. Installation of LessTif with pkg_add creates a directory /usr/lesstif, under which all of LessTif is placed. As the file /usr/lesstif/README explains, you should put /usr/lesstif/bin in your $path, add /usr/lesstif/lib to your LD_LIBRARY_PATH or to the options of ldconfig in /etc/rc, and point your compiler to include files and libraries by adding -I/usr/lesstif/include -L/usr/lesstif/lib to its command line. See also below. 6.2.3 Linux From Matthew Simpson : Lesstif Binary Installation The following procedure worked for installing the binary version 0.82 Lesstif onto my Redhat 4.2 Linux system. I did not have a previous installation of either the source or binary Lesstif, so this works from scratch. I am documenting this days later, so please correct as needed. The binary installation is simple: - After downloading the binary distribution, log in as root and place the file in /usr - gunzip it: gunzip lesstif-0.82-linux.tar.gz - untar it: tar -xvf lesstif-0.82-linux.tar The result will be this directory: /usr/lesstif - Remove the tar file if desired: rm lesstif-0.82-linux.tar - Edit /etc/ld.so.conf and add the following line for the untarred LessTif library: /usr/lesstif/lib - Run this: ldconfig Lesstif Window Manager: To ignore your default window manager and instead load mwm, make or copy these files as yourself or root (whichever you use) to your home directory: - Put a .xinitrc file in your home directory. Add this to the last line, replacing the call to any other window manager: eval "exec /usr/lesstif/bin/mwm" Or for better tracking, use this line instead: eval "exec /usr/lesstif/bin/mwm" -debug >"$HOME"/.MWM-errors 2>&1 (The redirections rules for > and 2>&1 syntax are specific to sh, which is what my startx script uses. The rules are slightly different for tcsh.) This will dump any errors to a file in your home directory called .MWM-errors. If no errors occur, this file will not get created. If this file already exists, new errors will be appended to it. To get a new file each time you log in or start x windows, add this to your .login or startx file: rm -f $HOME/.MWM-errors To automatically execute your window manager upon login, add this to the end of your .login file (this is using tcsh syntax): if ( ! -e /tmp/.X0-lock ) then echo "Starting X Windows..." rm -f $HOME/.MWM-errors startx endif - Copy this: cp /usr/lesstif/lib/X11/app-defaults/Mwm . This is where you set your personal app-defaults. Uncomment the lines mentioned at the end of this file to get some pretty borders. Here are some other things I changed: Double clicking an icon was set too fast. To slow it down: Mwm*doubleClickTime: 1000 To allow automatic window focus whenever the mouse pointer hits it: Mwm*keyboardFocusPolicy: pointer - Copy this to your home directory: cp /usr/lesstif/lib/X11/mwm/system.mwmrc .mwmrc Note that you should rename it from system.mwmrc to .mwmrc This is where you set up your personal root menues. If you use XFree86, look in /usr/X11R6/bin for most of the already-installed applications you like to execute through the root window pull-down menues. More menues and sub-menues can be added as desired. Since /usr/X11R6/bin is in your path, you need not type the full path names into .mwmrc. Applications in other directories will need paths or soft links set up. When setting up these two files I did not have a Lesstif mwm manual page available. However, if you have Unix and Motif available at work (such as on SGI products), just do a man on mwm and print it out for reference. Most will apply to Lesstif mwm. (Even though SGI uses their own version called 4Dwm, they still provide the mwm manual pages with the IRIX 6.2 release.) - run startx Hope this helps someone. These directions may be over simplified, but I wanted to be specific. Thanks for Lesstif. I am learning M*tif but have a long way to go. Matt Simpson 6.2.4 OS/2 The OS/2 binary distribution is provided as an InfoZip file. Go to your X11ROOT and unzip the archive. 7 After LessTif (Getting shared libraries working) Shared library configuration differs from system to system. Here is the lowdown on getting them to work on the systems that support them. - Linux There are two ways to have shared libraries available under linux: - Use the LD_LIBRARY_PATH environment variable. - Use ldconfig. The second option is only available to those with superuser access, so if you don't, or you specifically want to use the library that was just built (for running the tests), use the LD_LIBRARY_PATH variable. The LD_LIBRARY_PATH variable is to contain a colon separated list of paths to be searched for shared libraries. This variable is consulted before the information compiled by ldconfig, so even if you have LessTif already installed on your system you can use this variable to force the use of the newly built library. An example setting for LD_LIBRARY_PATH: $ LD_LIBRARY_PATH=/home/toshok/lesstif/libXm:/home/toshok/lesstif/libMrm $ export LD_LIBRARY_PATH If you have superuser access and want LessTif to be installed for system- wide use, make sure the directory to which the libraries were installed is listed in /etc/ld.so.conf. Then (as root) type 'ldconfig -v' to make them available. If you're not sure which library is being used (either the system-wide installed one, or one you've just compiled), use the 'ldd' command. After generating an executable linked dynamically with LessTif, type 'ldd '. This will output a list of the paths to all the shared libraries this executable depends on. - HPUX 9 Nothing additional needs to be done. Just make sure the linker can find the libraries when generating the executable (the -L flag). - NetBSD/FreeBSD/OpenBSD Same as for Linux.
