-Stripping LyX
--------------
-
-A LyX binary for linux is about 1M when compiled without debug-information
-and with dynamic libraries. If yours is much bigger you probably compiled
-it with debug-informations (-g). If you don't want to debug LyX just enter
-
- strip src/lyx
-
-before installing. Note that this is done automatically for public
-versions.
-
-
-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
- you did a 'make mrproper' in the kernel directory, because this
- removes some symbolic links that are needed for compilation. A 'make
- symlinks' in linux kernel sources fixes that.
-
- o If you have GNU gettext installed on your system (e.g. on linux),
- you will get tons of warnings like:
-
- bullet_forms.C:101: warning: passing `char *' to argument 1 of
- `__builtin_constant_p(int)' lacks a cast
-
- These are in harmless warnings caused by a bug in libintl.h, but
- will be solved if you use --with-included-gettext when configuring
- LyX.
-
- o On Digital 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 The configure script seems to hang while it is checking the LaTeX setup.
- We think that this is not a real problem, but rather a symptom of the
- fact that the ec-fonts are being rendered. This process can take quite
- some time, so the remedy is simply to have patience. (The fonts need to
- be rendered at some point to be usable anyways.)
-
- 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 There are several known bugs in gcc 2.7.xx that cause compiler
- errors. This is in particular the case in spellchecker.C under
- HP-UX 9.05 (ask Bernhard Iselborn <biselbor@rhrk.uni-kl.de> for
- more comments) and in lyxrc.C under Linux/Alpha or DEC OSF/1. In
- both cases, the solution is to recompile the offending file
- without optimization and resume the compilation process with
- 'make'. To make things simpler, you can use the option
- --with-gcc-hack of configure that will do that for you
- automatically.
-
- 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 There is a bug in gcc 2.7.[012] in the handling of const which can
- cause various unpredictable problems. If you experience weird
- crashes with a LyX compiled by gcc 2.7.[012], try to configure
- with the --with-broken-const flag and recompile. If this improves
- things, please report it to the mailing list. Note that this
- compiler bug is fixed in gcc 2.7.2.1 and in several Linux
- distributions of gcc 2.7.[012].
-
- This bug is currently not autodetected, but any code to do so
- would be welcome. A patch for gcc 2.7.2 is as follows:
-

- return temp;
- }
-
-
- 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
-warning, LyXSeriesNames not found in original or external symbol tables, value de
-
- 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.
-
- o Configure fails to work with cxx V5.0-3 on Digital Unix
- V3.2c. This is due to a bug in this particular version of cxx.
- Contact Achim Bohnet <ach@rosat.mpe-garching.mpg.de> for more
- details concerning this problem.
