I know now. gettext is required for maintainer mode and optional for normal one.
Version 0.15 or above is required to have the build working. Will send a patch for that.

Hi,

When compiling wine on another machine I got this error :

po/ar.po:359: keyword "msgctxt" unknown
po/ar.po:359:8: parse error
po/ar.po:591: keyword "msgctxt" unknown
po/ar.po:591:8: parse error

Is po files generation supposed to be done only in maintener mode ?
In any case gettext version check should be added in configure.ac. Which first version supports msgctxt ?

Thanks in advance
Bye
Christian
