[Scons-users] blocking execution until compilation is done

[Kenny, Jason L]

I think you miss that in my example I am trying to say you can define two targets.. one to build an item, and one to build and test an item ( ie no script wrapper.. just one target that does both). I think that is what you want. Ideally I have found that if you builds start getting large you will want easy targets for just building, vs the building and running of tests. This is mainly a start up speed issue.

I understand why you want to say a given action should happen in serial, such as tests that are sensitive to threading issues and load on the system. We have this issue here a lot. The trick is to understand that such tests are not deterministic and by simply running on different hardware, and perform differently. I not going to say I have a silver bullet for this, as this is a difficult problem.

I do see that at some point SCons will get a better taskmaster that will allow certain item to run only in serial to help with certain special cases, which other actions can happen in parallel.

While using two command-lines, or a wrapping script, is possible, it does not achieve the level of convenience I am hoping for. What I want is that I run a particular test, all the dependencies of that test should be built without me having to know the names of them. Sure, I could adopt a naming strategy where I always has "check-TARGET" and "build-TARGET" but I then need to start introducing more artificial targets and remember to follow this convention.

I'm not claiming this is some critical feature; I was really just asking whether it was possible, to which the answer appears no. It's just a small thing that would make some build scripts easier to use during development, and perhaps eliminate unnecessary build time.
