IMP build directory
by Daniel Russel 22 Sep '08

22 Sep '08

Copying the headers to the build/include directory and then building against the copies is problematic since they debugger will step you through the code in those copies rather than the actual header. Then if you change the file the debugger points you to your changes won't get committed and will get lost whenever someone happens to touch the original file, which could be quite a bit of time later, making it hard to remember the fix. It would be much better to either just leave the headers in a central include directory (and, if you want to enforce permissions, enforce them on a per directory basis), or create links instead (although this might complicate installation?).

Extension modules now live in the modules/ subdirectory
by Ben Webb 21 Sep '08

21 Sep '08

If, for example, you were saying "scons em" to build and test the em module, you should now say "scons modules/em" instead. Otherwise, everything is as it was before. A nice side effect is that "scons modules" will now build and test all of the IMP modules.

Just a couple of comments: - it would be really nice is the other packages used the logging support built into the IMP kernel. This makes controlling the complexity and where it goes much easier. - is there a reason that other modules don't use the imp kernel exception wrappers? Is this something to do with SWIG failing or a design decision? It seems to me uniformity in exception returns would also be quite nice.

I wouldn't expect gdb to work. There is winedbg (I just installed it) but I don't know how well that will work.

No, CGAL isn't built for Wine on synth yet, so IMP is a non-CGAL build.
