XMLTree.c:1016: error: void value not ignored as it ought to be
Normally I don't recommend trying to alter code when an installation throws an error - the problem is usually user-related (i.e. me) or totally unfixable. This is one exception:
If you get this error trying to install the R XML library from Omegahat
Don't give up. It is actually worth fixing this one.
Expand the tarball and alter the file called 'XMLTree.c'
The offending code:
Notice the disclaimer - if your libxml2 is up to date these methods are not necessary anyway.
So just delete those two methods and the directive they rode in on, from #ifdef to #endif
Recompress
tar -cvf XML_1.99-0.tar XML
gzip XML_1.99-0.tar
and install
R CMD INSTALL XML_1.99-0.tar.gz
If you get this error trying to install the R XML library from Omegahat
XMLTree.c: In function `xmlBufferWrite':

you seem like a smart guy. I can't get an update from Microsoft to install on my Mac. Can you tell me what's wrong?
