Top of Page MolArch+ - Error Messages
General
The following error messages may indicate problems with your MolArch+ installation:
  • "vogle X11.c couldn't open fontfile ..."
    The "hershey" fonts of the "libvogle" graphics library are not properly installed (see "MolArch+ - Prerequisites").

  • "... no file ".molarch+.key" or "molarch+.key" found
    ... no file ".molarch+.ini" or "molarch+.ini" for initialization

    These messages are warnings only, but if no main window of MolArch+ shows up, they most likely indicate that the $MOLARCH variable is not properly set to point to the directory were the MolArch+ parameter files are stored (see "MolArch+ - Installation").

  • "COLOR DEFINITION FILE NOT FOUND"
    The $MOLARCH variable is not properly set to point to the directory were the MolArch+ parameter files are stored (see "MolArch+ - Installation").

  • "ERROR - FAILED READING REGISTRY KEY"
    MolArch+ was unable to create and/or read the registry key from the ".molarch.register" file in your home directory (see "MolArch+ - Installation").

Files
The following error messages indicate problems reading files:
  • "sh: TMP_FILE.pdb: Permission denied ... open: No such file or directory ... Aborted"
    You don't have write permission at the current working directory from which you have evoked the "molarch+" command. MolArch+ was unable to temporarily unzip or write files to be processed. Change to a "writable" working directory.

Top of Page POVRAY - Error Messages
POVRAY
The following error messages indicate problems with your POVRAY configuration:
  • #include "colors.inc" ... Parse Error: Cannot open include file colors.inc.
    You need to configure POVRAY properly to manage the include files that where contained in the POVRAY distribution. MolArch+ will use for examples the colors defined in these files. You may have to edit your "~/.povrayrc" file adding the appropriate library path statements:
            Library_Path=/usr/local/lib/povray35
    	Library_Path=/usr/local/lib/povray35/include
    or the corresponding directory where POVRAY has been installed on your system.

  • #include "molatoms.inc" ... Parse Error: Cannot open include file molatoms.inc.
    You need to include the $MOLARCH directory from the MolArch+ installation in your POVRAY library path by editing your "~/.povrayrc" file. Try adding the following line:
            Library_Path=<directory>
    where <directory> is the same directory as indicated by the $MOLARCH environment variable.

  • sh: ... command not found.
    You need to edit the file $MOLARCH/molshowpov.com to setup the external POVRAY ray tracing program.
Top of Page VRML - Error Messages
VRML
The following error messages indicate problems with your VRML configuration:
  • sh: ... command not found.
    You need to edit the file $MOLARCH/molshowwrl.com to setup a external program capable of viewing VRML files.
