I hope we are at cross purposes here, or else Peter's suggestion won't fly - we need to be able to decouple some of these things from configure/build time and defer them to installation/runtime. Any other result will have us attracting curses from on high from the whole Windows community, and other binary packagers won't get what I understand some want. How about if we have a configuration flag --enable-relocation which would require a fixed layout based on an indeterminate root. This would have the following effects: . if prefix did not contain 'postgres' or 'pgsql' then 'postgresql' would be appended. . all *dir configure options would be forbidden - they would be based on the prefix as now, and since it would contain 'postgres' the simple layout we want would be used. . binaries would have a DEFINE which would mean they would know they should look for other binaries and shared files in locations which are fixed relative to their own location rather than in the hardcoded locations. None of this should need a single #ifdef WIN32 :-) (Would we need to turn off rpath for Unix in such a case? I suspect we would.) cheers andrew ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
