The low down: LyX currently uses a perl script called reLyX to convert .tex files to .lyx. It is showing its age, but should work 'most of the time'. The next version of LyX will have a new converter, tex2lyx, that is much more robust because it has a real TeX parser rather than a bunch of regular expressions. You can invoke reLyX from the comand line. (man reLyX). $ reLyX your_file.tex This will produce a LyX file your_file.lyx made up of a nasty mess of different LyX formats, so we then use a python script, lyx2lyx, to modify this file and create something in the current LyX format. $ lyx2lyx your_file.lyx > your_file_13x.lyx Doing this on your sample file produces the attached 'prabir_relyx_lyx2lyx.lyx'. I see that the labels are indeed messed up. If I were to do the same thing with your original file using tex2lyx, I would create a lyx file in the _current_ 14x-lyx format. $ tex2lyx prabir.tex > prabir_tex2lyx.lyx and must therefore 'go back' to the 13x-lyx format that your version of lyx understands. lyx2lyx does support this 'going back', but only the current cvs version of lyx2lyx, not the one you have. Anyway: $ lyx2lyx -t 221 prabir_tex2lyx.lyx > prabir_tex2lyx_lyx2lyx.lyx I attach this file too. As you can see, the conversion is perfect. So, conclusion: lossless conversion lyx->tex->lyx is possible, but you'll have to make an effort. First off, you'll have to grab the cvs sources. In the past I've suggested to people that they try and grab only the necessary bits, but that has turned out to be near-impossible to do, so I suggest you grab the whole repository. $ mkdir lyx && cd lyx $ cvs -d :pserver:[EMAIL PROTECTED]:/cvs/lyx login The password is 'lyx' (no quotes). $ cvs -d :pserver:[EMAIL PROTECTED]:/cvs/lyx co lyx-devel This will download the repository into a directory lyx-devel. $ cd lyx-devel In future, you can keep your tree up-to-date with $ cvs up No need to tell cvs where to find the repository anymore as the information is stored. However, do yourself a favour and put this in a file '.cvsrc' in your home directory $ cat .cvsrc diff -upN rdiff -upN update -dP To prepare the sources to be built: $ ./autogen.sh $ mkdir build && cd build $ ../configure --with-version-suffix That should be enough to get things ready. Try $ ../configure --help to see the wild range of options you can pass to configure. I suggest that you use '--with-version-suffix', which will eventually lead to a file 'tex2lyx-1.4.0cvs' being installed in /usr/local/bin and lyx2lyx being placed in directory /usr/local/share/lyx-1.4.0cvs/lyx2lyx/. That way, the two versions can co-exist. In general now I would suggest that you just type 'make', but that will build the whole of lyx and you just want the converters. Doing this myself: $ (cd boost && make) $ (cd src/support && make) $ (cd src/tex2lyx && make) That should give you and executable src/tex2lyx/tex2lyx. lyx2lyx needs no compilation. Finally, as root $ (cd lib && make install) $ (cd src/tex2lyx && make install) Good luck! -- Angus
