Quite in a hurry I am trying to setup MiKTeX 2.9 on the computer of a friend of mine. We started with the portable version but the problem is the same in the normal install.

Before the compilation of the .tex-file LuaLaTeX needs the font name database and the creation fails with this error message:

C:\miktex>mkluatexfontdb -vvv

luaotfload | Updating the font names database:
luaotfload | Font names database not found, generating new one.
             This can take several minutes; please be patient.
luaotfload | Updating the font names database:
luaotfload | blacklisted file: /System/Library/Fonts/STHeiti Light.ttc
luaotfload | Scanning TEXMF and OS fonts...mkluatexfontdb: Windows API error 67:
 The network name cannot be found.
mkluatexfontdb: Data: \\MiKTeX\]MPM[\fonts\opentype

The issue seems similar to this question, which unfortunately received no answers. Any help would be greatly appreciated.

What I can deduce so far from the error message is that mkluatexfontdb wants to access the network server \\MiKTeX which does not exist, and which I have never given as an option to search for. This happens with the current (25.03.12) portable version of MiKTeX 2.9 on Windows 7 64 but I could also reproduce it with the normal version.

In the documentation to luaotfload it is mentioned that %WINDIR%\Fonts will be searched but not any network server and there seems no way to disable this.

Edit: The only vaguely related environment variables are:

m;C:\Windows\System32\WindowsPowerShell\v1.0    SystemDrive=C:
TEMP=C:\miktex\miktex\temp    TEMPDIR=C:\miktex\miktex\temp    TMP=C:\miktex\miktex\temp    TMPDIR=C:\miktex\miktex\temp    USERDOMAIN=win7

2nd edit: The path to the fonts can also not be accessed (MWE):


Example text.

leads to the following output of lualatex:

This is LuaTeX, Version beta-0.70.1-2011080216 (rev 4277)
LaTeX2e <2011/06/27>

lualatex: Windows API error 67: The network name cannot be found.
lualatex: Data: \\MiKTeX\]MPM[\fonts\opentype

This is the output of kpsewhich in the directory of the .tex file:

C:\temp>kpsewhich --expand-path=$OPENTYPEFONTS
kpsewhich: Windows API error 67: The network name cannot be found.
kpsewhich: Data: \\MiKTeX\]MPM[\fonts\opentype

    luaoftload searches also the texmf trees and uses some environment variable. So check them (I haven't the time now to investigate.) – Ulrike Fischer Mar 26 '12 at 16:49
  • @UlrikeFischer: This is a fresh miktex portable installation. As far as I know there is no other texmf besides the installation directory. – Alexander Mar 26 '12 at 22:27
  • What do you get if you run in a document (with fontspec if possible, but without is also ok) \directlua{tex.print(-2,kpse.expand_path("$OPENTYPEFONTS"))}? – Ulrike Fischer Mar 27 '12 at 7:02
  • @UlrikeFischer: Thank you for looking into this, I added the output of the command you proposed. Additionally I tried with the fontspec package but received the same error message. – Alexander Mar 27 '12 at 11:55

    Hm. You are saying the document (without fontspec!) above leads to the same error? Then it can't be directly related to mkluatexfontdb. Does it disappear if you use e.g. \directlua{tex.print(-2,"abc")}? – Ulrike Fischer Mar 27 '12 at 12:03
