I'm sorry, maybe I should have clarified: Foo requires BAR_BIN to be present at runtime , so yes, I really do want it to be set in the module file of Foo. Foo provides a (GUI) wrapper for Bar, but it needs to know the location of the Bar binary. Rather than searching the path - as other programs might have done -, Foo uses the BAR_BIN environment variable to locate and call Bar (in fact, the installation instructions for Foo list that you have to set BAR_BIN).

The modextravars should be set in the Bar easyconfig if you wish to leverage it in Foo? Otherwise you just use something like preconfigopts = 'BAR_BIN=$EBROOTBAR/bin ' in the Foo easyconfig.

Thus, in the EasyConfig for Foo, I list Bar as a dependency. Now, Foo requires an environment variable BAR_BIN to be set that points to the Bar binary. Thus, what I would like to do in the Foo EasyConfig is something like: modextravars = {‘BAR_BIN’: ‘$EBROOTBAR/bin’} This doesn’t work: I get an error (something like ‘no variable EBROOTBAR’). I presume the reason is that in the modextravars step for 'Foo', the 'Bar' module isn’t actually loaded - thus EBROOTBAR is not set. I could use $root (which points to the FOO root, and does exist when modextravars is executed) and peal off the …/Foo/(version)-(toolchain), then add .../Bar/(version)-(toolchain), but this feels like a very dirty solution. Does anyone know of an elegant way to achieve this? And just to check: is it correct that the dependencies are not loaded when modextravars is executed?
