[Tex/LaTex] troubles with moderncv after Miktex update

moderncv

I have been using moderncv to generate some cover letters and CVs recently. Everything was working fine, until I have done a Miktex update. I keep getting the error Undefined control sequence. \makelettertitle for the following MWE (Which used to worjk without any problems!):

Any help is appreciated.

Update:
Following the log file, the errors are the following:

  • Undefined control sequence. \setlength{\makecvtitlenamewidth}{12cm}
  • Missing number, treated as zero. \renewcommand
  • Illegal unit of measure (pt inserted). \renewcommand

Which are respectively originating from the two commands:

 \setlength{\makecvtitlenamewidth}{12cm}
\renewcommand*{\namefont}{\fontsize{24}{29}\mdseries\upshape}

Best Answer

\makecvtitlenamewidth existed as part of moderncv 1.5.0, but was removed from moderncv 1.5.1 - the current latest version.

The current replacement seems to be \makecvheadnamewidth, which a default of 0pt (used in conditioning for an automatically set width).

The class has undergone numerous changes which makes older versions of documents incompatible with current versions. If you wish to keep the older formats, you need to maintain a temporary version of the class. Otherwise, you'll have to update your documents accordingly.
