Untill yesterday I had worked with Word, but my instructor recommended I start using LyX. I use windows, so I followed the wiki he recommended. Everything runs alright except when trying to compile to pdf, I recieved the error:

LaTeX Error: File `cp1255.def' not found.

It's worth mentioning that I tried to uninstall and install the 2.0.6 version, but got the same error, so I reinstalled 2.2.2.

How can I fix this? Thanks in advance.

Here is the log file for trying to compile a document with hebrew:

  • Can you post a minimal example .lyx file? Do the Hebrew manuals work for you? On Ubuntu, the Hebrew Intro and Tutorial manuals compile fine for me. – scottkosty Jan 21 '17 at 3:17
  • @scottkosty When trying to compile the manuals I get the same error. The file I got the log file in the main post contained only "אבג", or something along those lines, nothing more. – Itamar David Jan 21 '17 at 21:06
  • Do you have the file cp1255.def? If not, then you need to install the package that has it. On Ubuntu, the package "texlive-lang-other" has it. You might try to install the package "babel-hebrew", but I'm not sure how it works on Windows. – scottkosty Jan 21 '17 at 21:14
  • @scottkosty Yes, after some fiddling I installed the "babel-hebrew" package through miktex's package manager, and everything works now! Thanks! – Itamar David Jan 21 '17 at 22:39
  • Glad it worked! – scottkosty Jan 22 '17 at 2:30

On Windows, install the package "babel-hebrew" through MiKTeX's package manager.

On Ubuntu, if you are using TeX Live from the Ubuntu repos, install the package "texlive-lang-other".

On other systems, search for the package that contains the file "cp1255.def".
