Jonathan> Xemacs 21.1.14 crashes at startup on RedHat 7.2 system Jonathan> in windows mode. Probably "Hannibal Lecter" ld. Upgrade to 21.4; 21.4 is about to be promoted to stable, and there will never be a fix for this in 21.1. There are a raft of other changes in the GNU toolchain, each of which individually breaks the Linux unexec. It is not worth trying to keep up with them. You can try adding '--ldflags="-z nocombreloc"' to your configure flags, but this is known not to help in 21.4 with glibc 2.3, so 21.1 is most likely going to break for you, permanently (no fix except the portable dumper is known), on Red Hat when you upgrade to 8.x. -- 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.
