Robert, Do you think it is okay to manually edit the various build scripts to make them build as desired and then just record what was edited in the SPKG.txt file?
Also, how much software can we require the user have pre-installed on their system before building jmol-src.spkg? At this point we require they have a Sun JDK and ant installed. How many of the following packages can we also require they have pre-installed (if any)? > #ant-contrib. > #apache commons-logging. > #apache commons-lang. > #bcmail -Bouncy Castle Crypto. > #bcprov -Bouncy Castle Crypto The reason I am asking is that jmol will probably not be the only Java-based package to be added to Sage and, if dependencies like this are offloaded to the user's environment, they can be used by all Java-based Sage packages that need them. You had also mentioned adding an Ant spkg to Sage earlier. This is an interesting approach for dependency management, but if this route is taken there will need to be quite a few Java-based spkg packages created. Are we sure we want to bring Java-based packages into Sage in a big way? I know that Gentoo found it extremely challenging to get Java-based packages to work correctly with Gentoo. Here is an excerpt form a Gentoo Java manual: ---- "Bundled Dependencies One of the features of Java has always been "compile once, run everywhere." A consequence of this is that Java developers traditionally bundle all library dependencies with their project's distribution. While this might be convenient for the end-user, it rapidly becomes problematic from a packager's point of view. For example, project A depends on C, and project B depends on C, and you have project A and B installed, then you'd have two copies of C installed to support it. And if there's new release of C with a bug or security fix , you would want both A and B to take advantage of it. " ---- Perhaps a better way to solve the jmol-src problem is to tell the builder to build the following jars on their own and then place them into the jmol jars directory before building jmon-src?: Acme.jar gnujaxp-onlysax.jar junit.jar vecmath1.2-1.14.jar ant-contrib.jar gnujaxp.jar netscape.jar commons-cli-1.0.jar itext-1.4.5.jar saxon.jar Ted --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://sage.scipy.org/sage/ and http://modular.math.washington.edu/sage/ -~----------~----~----~----~------~----~------~--~---
