- libhelp - a html based help system for osf/motif applications
- -------------------------------------------------------------
-
- welcome to libhelp 1.8.1 (Jun 28. 95)
-
- this Readme details compilation steps for libhelp. more complete
- information and documentation on libhelp is available as part of
- the online help system it implements. see section "getting more
- help" for getting more information. this is $Revision: 1.11 $ of
- the Readme file.
-
- about
- -----
-
- libhelp is a comprehensive hypertext-help-system for OSF/Motif(tm)
- applications which uses the html widget from NCSA Mosaic(tm)
- version 2.4. the help browser provides hypertext links, different
- fonts, inlined images and a lot of more elements known from www
- (world wide web) browsers. it has a document history and
- implements buffer and image cache methods.
-
- libhelp provides two interface functions for getting help and
- setting resources. it eases the task of writing the application
- help. menu and context sensitive help are supported. Lowlevel
- Motif and X stuff is hidden from the application developer (and of
- course the user too). libhelp works with (at least) ansi-c and c++
- applications.
-
- a simple (but impressive) standalone help browser `xmhelp' is
- included in the libhelp distribution.
-
- an alternative implementation for the libhelp interface (named
- `libhlpclient') provides client-server help. this library
- transparently starts and controlls a help server (currently xmhelp
- or NCSA Mosaic(tm)) for the applications help requests.
-

- libhelp needs 3 libraries (which are shipped with the libhelp
- distribution: the HTML widget library, the ButtonFace library and
- the Xpm library). see the file "Licence" for licencing and
- copyright details for them.

- source
- ------
-
- future versions of libhelp can be obtained by anonymous ftp from
-
- ftp.informatik.uni-stuttgart.de:/pub/libhelp/libhelp-<ver>.tar.gz
-
- where <ver> denotes the version number.
-
- note: libhelp will be officially released in august 95. if there
- is nothing on ftp.informatik.uni-stuttgart.de write me for a copy.
-
- platforms
- ---------
-
- libhelp is known to compile on the following platforms (in
- alphabetical order):
-
- hp (hp/ux A.09.03 A 9000/730 with c89, x11r5 and motif 1.2)
- ibm (aix 3.2.5 with cc, ibm x11r5 and motif-1.2).
- pc (linux 1.x with gcc, x11r5 and motif-1.2).
- sgi (irix 5.1.x).
- sun 4 (sunos 4.1.x with gcc, x11r5 and motif 1.2).
- sun 5 (solaris 1.2 with gcc, x11r5 and motif 1.2).
-
- compilation instructions
- ------------------------
-
- libhelp sources are written in ansi-c. you will need a working
- ansi-c compiler (e. g. gcc) to compile libhelp. libhelp requires
- x11 and osf/motif(tm). we use x11r5 and motif-1.2. we don't know,
- if it compiles with x11r4 and motif-1.1, but there will be a great
- chance that it will.
-
- in order to compile libhelp and the standalone helpbrowser xmhelp
- you will need a working imake. the global Imakefile defines the
- variable LIBDIRS to 'libhelp libButtFace libhtmlw'. if you don't
- have the xpm library (version 3.4) you will need to add libXpm to
- LIBDIRS to use the xpm library that is shipped with libhelp.
-
- to build libhelp, type:
-
- xmkmf
- make Makefiles
- make
-
- if you want to use a different compiler than gcc type
-
- make CC=<compiler>
-
- in the last step.
-
- you can add additional include dirs in INCS, optimisation flags in
- COPT, additional libraries for your host in LIBS and other
- makefile definitions in DEFS. for example
-
- make CC=cc LIBS='-lbsd -lregexp' INCS='-I/usr/bsdinclude' \
- COPT='-g' DEFS='-DDEBUG -Wall'
-
- you can hardcode the search path for helpfiles and images with the
- preprocession macro HELP_PATH. per default, it is set to
-
- "/usr/local/help:../help:help:../images:images:."
-
- but you can compile in your local help directories, for example
-
- make DEFS='-DHELP_PATH=\"/usr/help:/usr/images\"'
-
- if you want `/usr/help' and `/usr/images' be searched for help
- files and images. at runtime, you can add entries to the help path
- via the environment variable LIBHELPPATH.
-
- supposed there are no compilation errors this results in a single
- executable file xmhelp/xmhelp and the library files
- libhelp/libhelp.a, libButtFace/libButtFace.a libhtmlw/libhtmlw.a
- and if choosen libXpm/libXpm.a.
-
- to link libhelp to other applications you should include the file
- libhelp/help.h into the sources. link the libraries in the
- following order:
-
- -lhelp -lButtface -lXpm -lXm -lXmu -lXt -lX11 ...
-
- if you don't want the help browser to be linked in, you can
- alternatively use the libhlpclient library. for more information,
- see the Readme file in the libhlpclient directory.
-
- minimum installation
- --------------------
-
- in order to have the right icons in the history page, you'll need
- to copy at least the images
-
- icon-history.gif icon-index.gif libhelp-bar.gif
-
- from the help/ directory to a place pointed by the LIBHELPPATH (or
- internal HELP_PATH). To use the libhelp documentation as part of
- your help system, you need to copy all files ending in .html and
- .gif to such a directory.
-
- additionally, you can place libhelp.a and help.h in a global place
- where compiler and linker will find them. On my systems, libhelp.a
- is in /usr/local/lib, help.h is in /usr/local/include. Also you
- you might want to move xmhelp to a directory in your PATH
- (necessary for using xmhelp as help server).
-
- i use libhelp as a shared library. for example, my xmhelp browser
- is just about 10 kbytes. if you try to create shared libraries for
- your system, please send me information about it. it may be
- distributed in further releases.
-
- X default resources
- -------------------
-
- `xmhelp' includes a set of fallback X resources that provide
- reasonable screen display properties for color displays.
-
- the default resource class name for the libhelp library is
- `Libhelp'. your application can override this class name by a
- interface funtion (e.g. giving it the class name of your
- application).
-
- getting more help
- -----------------
-
- libhelp provides a comprehensive help system. it offers a set of
- example help files and images documenting itself. the help texts
- are written in the html (hypertext markup language) language.
-
- the libhelp-index.html document is designed to be added to your
- application as a "help for help" entry. feel free to add the help
- documents to your application. (or contribute if you have better
- ones (e.g. more elaborate english).
-
- if you have built libhelp successfully you can view the online
- help files with the standalone browser `xmhelp'. probably you
- need to set the environment variable LIBHELPPATH to the directory
- "help" in the libhelp distribution.
-
- at any time (before you've compiled libhelp or if it was not
- possible to do so) you can view the online help any www client
- which can display html files e.g. NCSA Mosaic(tm). change to the
- directory "help/" and start your www client on the index file
-
- libhelp-index.html.
