<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hi, all: Sorry to have to start a new thread -- my yahoo account lost track of some of the responses to my earlier posts and I was unable to formally respond to them. --- In short, by using gcc 3.4 as suggested by Peter Ross and others, I was able to build mercury with all grades -- smoothly too. As a result, so for many examples, such as eliza.m, I could compile and run C, java and erlang versions. This was my original goal and I'm pleased it worked out. For reference, here was what Peter Ross had suggested and which worked for me. ==================================================== sudo apt-get install gcc3.4 CC=gcc-3.4 ./configure --prefix /home/hsdl/apps/mercury_again5 --disable-most-grades make PARALLEL=-j2 install ==================================================== Thanks to everyone for your generous responses. -- Zach </td></tr></table>
