Subject Errors Building with gcc 3.4.3 (@ token in preprocessor expressions)
Date Wed, 06 Jul 2005 18:43:12 GMT
All,

After learning about log4cxx and reading the introduction, I was quite excited to start using
it.  But, given the warning on the homepage, I decided to wait for version 0.9.8 to come out.
 After months of waiting, I finally downloaded the CVS HEAD.  When is the next version expected
to be released?

I am having trouble building from the CVS HEAD.  I'm working on a RedHat Enterprise Linux
Core 4 box, using gcc 3.4.3 (which I've noticed is a lot more picky than the version in RedHat
9.0).  With a quick search through the mailing list archives, I didn't see this issue, but
please direct me there if I missed it.

I'm building with configure/make, since I don't have ant.  When building, I get the following
errors:

In the hopes of finding a quick fix, I removed the @ symbols in log4cxx.h (without exploring
why they're there).  The compile continued, but resulted in this error (which seems to probably
be a result of my change):

Can anyone explain the @ symbols or help with these errors?

Thank you,
