Nightly builds are not usable with Marlin

[tmadlener]

The new setup for the install prefixes for the nightly builds puts equal signs (specifically =develop) into the paths. This breaks workflows that use Marlin using paths as input variables, the most important one being $lcgeo_DIR, e.g.

Marlin --constant.lcgeo_DIR=$lcgeo_DIR [...]

Marlin uses the = as delimiter between the argument key and its value for parsing and cannot deal with additional = signs in the value.

Does it work if you quote the arguments?

[tmadlener]

No, unfortunately that doesn't fix things. Neither "$lcgeo_DIR" nor quoting the expanded variable changes things. The quickest and lowest effort workaround for the moment is probably to create a local symlink and then use that.

ln -s $lcgeo_DIR lcgeo_DIR
Marlin --constant.lcgeo_DIR=./lcgeo_DIR [...]

Do we still have no better solution for this?

maybe it should also go into #502 @jmcarcell?

[jmcarcell]

No better solution right now, I've just added it to #502

[tmadlener]

This has changed in upstream spack to use a _ instead of a =. Hence, everything works again in nightly builds.
