Are you building in /usr/src, or are your sources located some place else? Really need the log that includes the cc command line, as that has the tell tell -I/usr/src/sys in it. That component is totally bogus! At no time should a src tree rooted at /usr/src-topo be trying to use files from /usr/src/. > If the two problems are related, should the subject line on the bug > report be changed? It could be, but more info would be needed. In my case I was able to proove it out as my compile from /usr/src-topo worked just fine after I copied my 3 modified header files to /usr/src. -- Rod Grimes rgrimes@freebsd.org
