Subject: Prevent build of <lang>.gmo in case of error.
X-Git-Tag: 2.1.0beta2~83
X-Git-Url: https://git.lyx.org/gitweb/?a=commitdiff_plain;h=075d90394129001651643b95887b3ffee404529c;p=lyx.git

Prevent build of <lang>.gmo in case of error.

Given erroneous <lang>.po file, this yields to error on first call
to make. Nonetheless a new <lang>.gmo file is created. The following
calls to make do not get an error.
This patch prevents the <lang>.gmo creation on error.

Problem spotted by Scott.
