Re: xemacs-21.5.14 build failure: configure breaks because of no libjpeg.so.62

Ed> Another bug caused by configure adding libraries to the Ed> compiler command line when they do not exist (or at least, are Ed> not in the linker path).

A system where the header files can be found with the standard path, but the libraries cannot, is broken IMO. In my queue, this is very low priority (if I do invest time in this, I'm not going to leave it at just the libraries that bug Ed Avis, I'm going to audit all 5400+ lines of configure.in for similar bugs ;-). Partial patches welcome, though. I _suspect_ that this would more or less be automatically fixed by a port of our configure script to autoconf 2.5x. N.B. All our configure hackers are currently involved with day jobs; my best guess on ETA for this is Real Soon Now. -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
