Note for CVS checkouts
----------------------
If you have checked this out from CVS, you need to have
automake, autoconf, and gettext installed. Then,
type "./autogen.sh" to build the needed configuration
files and proceed as stated below.
Compiling and installing LyX
============================
Quick compilation guide
-----------------------
These four steps will compile, test and install LyX:
1) ./configure
configures LyX to your system.
2) make
compiles the program.
3) src/lyx
runs the program so you can check it out.
4) make install
will install it. You can use "make install-strip" instead
if you want a smaller binary.
Requirements
------------
You will need to have both an Xforms library and Xpm library to compile
LyX. It is imperative that you have the correct versions of these
libraries, and their associated header files.
As of LyX version 1.1.5, you will need to have Xforms library and
header version 0.88 or 0.89. Version 0.88 is a stable release and the
recommended version, but 0.89.6 seems to be work very well too. On
some systems, such as linux ELF, there are shared library versions of
the Xforms library, which require an installation step to configure
the system.
Xforms is available (free) only in binary format, source code is not
available. If it is not available for your machine, contact the Xforms
developers to request a version for your system. You can get it from
http://world.std.com/~xforms/
ftp://ncmir.ucsd.edu/pub/xforms/
ftp://ftp.lyx.org/pub/xforms/
ftp://ftp.fu-berlin.de/unix/X11/gui/xforms
ftp://ftp.cs.ruu.nl/pub/XFORMS/
In addition, you must have libXpm version 4.7 (or newer; 4.8 rumoured
to work).
To use the thesaurus, you will need to install libAikSaurus, available
from :
http://aiken.clan11.com/aiksaurus/
You will also probably need GNU m4 (perhaps installed as gm4).
libXpm can be found at:
http://www.funet.fi/pub/Linux/sunsite/X11/libs/!INDEX.html
(or similar locations at other sunsites like sunsite.unc.edu)
You will also need a recent C++ compiler, where recent means that the
compilers are close to C++ standard conforming. Compilers that are
known to compile LyX are egcs 1.1.x, gcc 2.95.x and later, and Digital
C++ version 6.1 and later. Please tell us your experience with other
compilers. It is _not_ possible to compile LyX with gcc 2.7.x and
2.8.x, and this is not likely to change in the future.
Note that, contrary to LyX 1.0.x, LyX 1.1.x makes great use of C++
Standard Template Library (STL); this means that gcc users will have
to install the relevant libstdc++ library to be able to compile this
version.
If you make modifications to files in src/ (for example by applying a
patch), you will need to have the GNU gettext package installed, due
to some dependencies in the makefiles. You can find the latest version
from:
ftp://ftp.gnu.org/gnu/gettext-0.10.xx.tar.gz.
LyX contains a hack to work around this, but you should not rely too
much on it.
Finally, the two following programs should be available at
configuration time:
o Perl (at least 5.002) is needed for the reLyX script. reLyX will
not be installed if perl is not found. If the environment
variable PERL is set to point to some program, this value will be
used, even if the program does no exist (this can be useful if
the machine on which LyX is built is not the one where it will
run).
o LaTeX2e should be correctly setup for the user you are logged
as. Otherwise, LyX will not be able to run a number of tests. Note
that users can run these tests manually with Option->Configure.
Creating the Makefile
---------------------
LyX can be configured using GNU autoconf utility which attempts to guess
the configuration needed to suit your system. The standard way to use it
is described in the file INSTALL.autoconf. In most cases you will be able
to create the Makefile by typing
./configure
For more complicated cases, LyX configure takes the following specific
flags:
o --with-extra-lib=DIRECTORY that specifies the path where LyX will find
extra libraries (Xpm, xforms) it needs. Defaults to NONE (i.e. search
in standard places). You can specify several directories, separated
by colons.
o --with-extra-inc=DIRECTORY that gives the place where LyX will find
xforms headers. Defaults to NONE (i.e. search in standard places).
You can specify several directories, separated by colons.
o --with-extra-prefix[=DIRECTORY] that is equivalent to
--with-extra-lib=DIRECTORY/lib --with-extra-inc=DIRECTORY/include
If DIRECTORY is not specified, the current prefix is used.
o --with-version-suffix will install LyX as lyx-<version>, e.g. lyx-1.2.0
The LyX data directory will be something like <whatever>/lyx-1.2.0/.
Additionally your user configuration files will be found in e.g.
$HOME/.lyx-1.2.0
You can use this feature to install more than one version of LyX on
the same system. You can optionally specify a "version" of your own,
by doing something like : ./configure --with-version-suffix=-latestcvs
o --enable-optimization=VALUE enables you to set optimization to a
higher level as the default (-O), for example --enable-optimization=-O3.
o --disable-optimization - you can use this to disable compiler
optimization of LyX. The compile may be much quicker with some
compilers, but LyX will run more slowly.
There are also flags to control the internationalization support in
LyX:
o --disable-nls suppresses all internationalization support,
yielding a somewhat smaller code.
o --with-included-gettext forces the use of the included GNU gettext
library, although you might have another one installed.
o --with-catgets allows to use the catget() functions which can
exist on your system. This can cause problems, though. Use with
care.
o You can also set the environment variable LINGUAS to a list of
language in case ou do not want to install all the translation
files. For example, if you are only interested in German and
Finnish, you can type (with sh or bash)
export LINGUAS='de fi'
before running configure.
Moreover, the following generic configure flags may be useful:
o --prefix=DIRECTORY specifies the root directory to use for
installation. [defaults to where lyx has already been installed or
/usr/local]
o --datadir=DIRECTORY gives the directory where all extra LyX
files (lyxrc example, documentation, templates and layouts
definitions) will be installed.
[defaults to ${prefix}/share/lyx${program_suffix}]
o --bindir=DIRECTORY gives the directory where the lyx binary
will be installed. [defaults to ${prefix}/bin]
o --mandir=DIRECTORY gives the directory where the man pages will go.
[defaults to ${prefix}/man]
Note that the --with-extra-* commands are not really robust when it
comes to use of relative paths. If you really want to use a relative path
here, you can prepend it with "`pwd`/".
If you do not like the default compile flags used (-g -O2 on gcc), you can
set CXXFLAGS variable to other values as follows:
o CXXFLAGS='-O2' (sh, bash)
o setenv CXXFLAGS '-O2' (csh, tcsh)
Similarly, if you want to force the use of some specific compiler, you can
give a value to the CXX variable.
If you encounter problems, please read the section 'Problems' at the end of
this file.
In particular, the following options could be useful in some
desperate cases:
o --enable-warnings that make the compiler output more warnings during
the compilation of LyX. Opposite is --disable-warnings. By default,
this flag is on for development versions only.
o --enable-assertions that make the compilier generater run-time
code which checks that some variables have sane values. Opposite
is --disable-assertions. By default, this flag is on for
development versions only.
o --with-broken-headers that provides prototypes to replace functions
not correctly defined in SunOS4 and SCO header files. Its only effect is
to suppress a few warnings. It is autodetected by default.
o --without-latex-config that disables the automatic detection of your
latex configuration. This detection is automatically disabled if
latex cannot be found. If you find that you have to use this
flag, please report it as a bug.
o --without-liberty suppresses the detection of the -liberty library
(see the section 'Problems').
Compiling and installing LyX
----------------------------
Once you've got the Makefile created, you just have to type:
make all
make install
All should be OK ;)
Since the binaries with debug information tend to be huge (although
this does not affect the run-time memory footprint), you maight want
to strip the lyx binary. In this case replace "make install" with
make install-strip
BTW: in the images subdirectory there is also a small icon "lyx.xpm",
that can be used to display lyx-documents in filemanagers.
If configure fails for some strange reason
------------------------------------------
Even when configure fails, it creates a Makefile. You always can check
the contents of this file, modify it and run 'make'.
Compiling For Multiple Architectures
------------------------------------
You can compile LyX for more than one kind of computer at the same
time, by placing the object files for each architecture in their own
directory. To do this, you must use a version of `make' that supports
the `VPATH' variable, such as GNU `make'. `cd' to the directory where
you want the object files and executables to go and run the
`configure' script. `configure' automatically checks for the source
code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile LyX for one architecture at a time in
the source code directory. After you have installed LyX for one
architecture, use `make distclean' before reconfiguring for another
architecture.
Preparing a binary distribution for the use of others
------------------------------------------------------
o Compile LyX with the right compiler switches for your
architecture. In particular you might want to ensure that
libraries like xforms and xpm are statically linked. To this end,
you can use a command like
make LYX_LIBS='/foo/libforms.a /bar/libXpm.a'
Moreover, make sure you use the --without-latex-config switch
of configure, since others might not be interested by your
configuration :-)
o Create a file README.bin describing your distribution and
referring to *you* if problems arise. As a model, you can use the
file development/tools/README.bin.example, which can be a good
starting point.
o Type `make bindist'. This will create a file
lyx-1.xx.yy-bin.tar.gz. Rename it to reflect you architecture
and the peculiarities of your build (e.g. static vs. dynamic).
o Check that everything is correct by unpacking the distribution
in some private place and running it. In particular, check the
output of `ldd lyx' to know which libraries are really needed.
o Upload your binary file to ftp.devel.lyx.org:/pub/incoming, and
notify larsbj@lyx.org.
Problems
--------
This section provides several hints that have been submitted by LyX
team member or users to help compiling on some particular
architectures. If you find that some of this hints are wrong, please
notify us.
o If you have problems indicating that configure cannot find a part of
the xforms or Xpm library, use the --with-extra-lib and --with-extra-inc
options of configure to specify where these libraries reside.
o Configure will seemingly fail to find xpm.h and forms.h on linux
if the kernel headers are not available. Two cases are possible:
- you have not installed the kernel sources. Then you should
install them or at least the kernel-headers package (or
whatever it is called in your distribution).
- you have the sources, but you did a 'make mrproper' in the
kernel directory (this this removes some symbolic links that
are needed for compilation). A 'make symlinks' in linux kernel
sources fixes that.
o if you are using RedHat Linux 7.x, you must make sure you have the
latest updated gcc and related packages installed (at least -85),
or LyX will not compile or will be mis-compiled.
o if you get an error message when compiling LyX that looks like this :
../../src/minibuffer.h:17: using directive `Object' introduced
ambiguous type `_ObjectRec *'
then you need to upgrade the version of the xforms library you have
installed.
o It is possible to compile lyx with Tru64 Unix cxx compiler
version 6.2, provided one uses
CXX='cxx -std strict_ansi'
CXXFLAGS='-ptr /tmp/lyx_cxx_repository -g'
CC=cc
Note that this will not work when compiling directly from the cvs
repository, due to the tricks used by automake for dependencies. Ask
Jean-Marc.Lasgouttes@inria.fr for a workaround.
o On Tru64 Unix, you may have to compile with
--with-included-string to work around a Tru64 linker limitation
(the STL string template creates names which may be too long). We
also had reports that it helps with gcc 2.95.2 on solaris 2.6.
o On Tru64 Unix with cxx, you may have a compilation error in
lyx_main.C if you have GNU gettext installed. This is due to a bug
in gettext. To solve this, you can either (1) configure with
--with-included-gettext or (2) add -D__STDC__ to cxx flags.
o According to John Collins <collins@phys.psu.edu>, on SunOS 4.1.3 you may
find two sets of X libraries, and they are of course incompatible :-)
One is the set provided as part of OpenWindows, and one is the standard
X distribution (e.g., X11R5). If you encounter problems (or if, for
some obscure reasons configure cannot find your X libraries) you can
use the following options:
o --x-libraries=DIRECTORY that indicates where the X libraries reside.
o --x-includes=DIRECTORY that indicate where the X include files reside.
The standard X11R5 libraries should work when the OpenWindows ones
don't.
o Some systems lack functions that LyX needs. To fix this, configure
tries to link against the -liberty library, if it is available.
If you experience problems with missing symbols at link time, you
could try to install libiberty.a, which comes with several GNU
packages (in particular libg++). In any case, please report your
problems to lyx-devel@lists.lyx.org.
The option --without-liberty disable the detection of -liberty. It
is meant for debugging purpose only.
o According to David Sundqvist <David_Sundqvist@vd.volvo.se>, some
changes are needed to compile with aCC on HP-UX 10.20. These are the
relevant changes in the makefile (with comments tagged on):
CXX = /opt/aCC/bin/aCC
CXXFLAGS = -O +inst_none # The aCC compiler tries to run instantiations
# which currently break.
LIBS = -lforms -lXpm -lSM -lICE -lc -lm -lX11 -lCsup # must link with Csup
LDFLAGS = -L/opt/aCC/lib # perhaps not needed.
o On Digital Unix with gcc, you can get warnings like
warning, LyXFamilyNames not found in original or external symbol tables, value defaults to 0
These concern symbols beginning with an uppercase letter and seems
to be harmless. Similarly, the compilation can end with the
following warning:
/bin/ld:
Warning: Linking some objects which contain exception information sections
and some which do not. This may cause fatal runtime exception handling
problems (last obj encountered without exceptions was ../intl/libintl.a).
You can safely ignore it.
