It should not be, and certainly is not for a clisp not built using the sage spkg. I used a different approach in the mandriva package. Instead of using the SAGE_CLISP_DISABLE_READLINE_HACK environment variable, I changed a bit the behavior of the clisp -I option (patch credit to Sam Steingold, after asking in clisp-devel): http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/clisp/current/SOURCES/clisp-noreadline.patch?revision=418280&view=markup And added this change to the maxima script, to pass -I to clisp if --disable-readline is used: http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/maxima/current/SOURCES/maxima-5.19.1-clisp-noreadline.patch?revision=421784&view=markup Since you say you are searching for the cause of problems in sage's interface to maxima, this patch to allow building ecl backend may also be useful: http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/maxima/current/SOURCES/maxima-5.20.1-ecl-ldflags.patch?revision=514331&view=markup And this sagemath patch to actually allow using also clisp and gcl backends, and passing all doctests: http://svn.mandriva.com/cgi-bin/viewvc.cgi/packages/cooker/sagemath/current/SOURCES/sage-4.3.3-maxima.patch?revision=524719&view=markup The problem with clisp and gcl is that, because the pexpect interface used by sage allocates a pty, it causes the lisp interface to consider it is running in an interactive mode, and redirects stderr to stdout. The solution for clisp was easier, but gcl required sending a ":lisp <form>" command. But the sage interface appears to still be somewhat fragile, as if one mistakingly adds two ";", it will hang any lisp backend, due to the pexpect interface loosing sync. > Francois Paulo -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org To unsubscribe from this group, send email to sage-devel+unsubscribegooglegroups.com or reply to this email with the words "REMOVE ME" as the subject.
