For the past few days, I have been having problems compiling Inkscape from CVS. First, the error involved pt_BR.po. Now, it is choking on it.po:1989: message catalog has plural form translations... it.po:10: ...but header entry lacks a "nplurals=INTEGER" attribute make[2]: *** [it.gmo] Error 1
I am running Fedora Core 3, fully updated. When I installed, I installed EVERY package, so there should be no issues with missing devel packages. One other thing: up until recently, I have had no problems compiling Inkscape from CVS on this computer.
Not reproducible here.
Because you can pin down exactly when you no longer could compile CVS, it should be easy for you to tell which changes of CVS evoke the problem for you. So you have a workaround.
As to the cause, note that it appears no other people have reported the problem. To be 100% sure, please use the bug tracker with all your given information.
