Still not built GAIA. In fact the more I try the further the build regresses. Now I can't even make "./configure -C" work. There is an undefined PREFIX token. It first showed during "make world" for tclsys/tclx. rlsul1.bnsc.rl.ac.uk> ./configure -C configure: loading cache config.cache checking for java... (cached) /stardev/java/jre-1.4.1_06-ix86_Linux/bin/java checking whether make sets $(MAKE)... (cached) yes checking whether ln -s works... yes configure: creating ./config.status config.status: creating Makefile configure: configuring in applications configure: running /bin/sh './configure' --prefix=%%PREFIX%% '-C' --cache-file=../config.cache --srcdir=. configure: error: expected an absolute directory name for --prefix: %%PREFIX%% configure: error: /bin/sh './configure' failed for applications Now I'm sure if I avidly read SSN/78 it will tell me what to do, but I shouldn't have to. Tell me that these tclsys upgrades will be rare events... Malcolm
