Features of precompiled binaries

[vaubee]

I’ve been using precompiled binaries to install ROOT on ubuntu machines, and I noticed that the features included in the binaries changed quite a bit going from 6.28 to 6.30 (but also a bit between 6.26 and 6.28). Is there any documentation which features are included in which precompiled version? Or is it just a matter of downloading a version, unpacking it, and then checking what’s included?

I found that 6.28.02 has all the features of 6.26.10 plus “builtin_gtest”, whereas 6.30.02 misses a lot of the features of 6.28.02, like “exceptions”, “fftw3”, “fortran”, “imt”, “mathmore”, “shadowpw”, “soversion”, and a lot of the “builtin_” features. The only additional ones I see in 6.30.02 are two “test_distrdf_” ones and
“proof” (which I thought was deprecated?).

Below is a list of features for the different binaries for ubuntu:

Hi,

Thanks for your observation.

The change is due to a complete rewrite of our CI/CD system. The approach based on which we build our binaries changed for major distros: we now try to rely as much as possible on the packages provided by the distros, without including the built-in ones.

I apologise if this caused an inconvenience to you and acknowledge that these behaviours should be documented in a more complete way in the future.

Best,
Danilo
