Subject Re: Newbie Usage Question: Compile Error 'getError is not a member of log4cxx::Level'
Date Sun, 30 Mar 2008 15:27:06 GMT
I have download the latest version via subversion. The solution you
provided worked under ubuntu gutsy. I compiled the project with
autogen.sh generated configure script. Ant build failed. It somehow
thinks that it is building under windows. I do not why. I tried to run
windress somewhere and failed.

Thanks for the helpful and fast response.
