Yes.

Or more to the point: I understand the problem. ;) I have built a version of Axiom using the most recent gcl-2.6.8pre from your CVS and Axiom source from the build-improvements branch of Axiom Silver with the following gcl configure options: GCLOPTS="--enable-debug --disable-xgcl --enable-vssize=65536*2 --enable-statsysbfd --enable-maxpage=196*1024" Note: This is the same version (except for --enable-debug) that I used to test your recent patches for the new gcl-2.6.8pre. You should be able access it on axiom-developer.org by setting: $ export AXIOM=/home/page/axiom.build-improvements/mnt/linux $ export PATH=$AXIOM/bin:$PATH > > > > The problem is not the 'xxx.erlib' directory as such but rather the > > failure to overwrite the existing 'xxx.NRLIB' directory.

Another bug?? Ok, forget that for now. '/var/zope/var/LatexWiki' is where the directory XPRIMARR.NRLIB lives. When compiling SPAD source code Axiom wants to replace the existing XPRIMARR.NRLIB with another directory called XPRIMARR.erlib. The problem seems to be that the gcl function that Axiom uses to do this will not even allow the directory XPRIMARR.NRLIB to be over written or deleted even though similar gcl functions can delete the individual files in that directory. Try it this way: ---------------- $ cd /var/zope/var/LatexWiki $ AXIOMsys AXIOM Computer Algebra System Version: Axiom (build improvements branch) -- 2006-08-08 Timestamp: Monday August 21, 2006 at 17:40:41 ------------------------------------------------------------------------ ----- Issue )copyright to view copyright notices.
