Re: [xml] If libxml2 headers refer to libxml/*.h, why is it installed into libxml2/libxml?

Please tell us the full compiler invocation, otherwise we can't figure out what's going on.

Merely building libxml doesn't put the headers in a place where user programs can find it. You may need to run "make install" too (usually a root, or via sudo).

tree.h contains "#include <libxml/xmlversion.h>". If /Users/jcarpen/local/include/libxml2 is not on the compiler's include search path (e.g. via -I/Users/jcarpen/local/include/libxml2) then the compiler won't find it.
