The way this usually works is that packages are shipped with the output of flex, so that flex doesn't have to be run again if the user doesn't have it. In this case that also seems to be the case, since the singular package includes src/Singular/libparse.cc. However, it's one second older than libparse.l. A 'touch src/Singular/libparse.cc' in the spkg-install should work around this, I think. -Willem Jan -- 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
