Hi, http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40004 was a bug report that I filed on the missing plugin headers.
That is now resolved - the headers are installed. I've closed the bug report. However I'm not sure how my application / buildsystem is meant to find the headers. Is there a way gcc could tell me? Alternatively, could there be a .pc (pkg-config) file. Brad
