[Bioc-devel] is it possible to disable i386 builds on bioconductor

[Thomas Girke]

Dear Hervé and Martin,

It seems the above problem on the Windows builds has been resolved for some
time now. However, any updates on Linux in the release branch are not
taking effect since some/all of the Openbabel dependencies are not
available on the corresponding Linux build system (here Ubuntu 18.04).
However, Ubuntu 20.04 seems to be fine but may not be used to create the
source download instance at the moment? As a result, the package is only
up-to-date for Windows and OSX (ChemmineOB_1.28.2.) but not Linux (still at
ChemmineOB_1.28.0.tar.gz):
http://bioconductor.org/packages/release/bioc/html/ChemmineOB.html. To fix
this, one suggestion would be whether the functional build from the 20.04
system could be pushed instead of 18.04? Not sure whether this is less
effort than installing the dependencies on 18.04 that may be discontinued
soon - just a suggestion/question?

On the development branch the situation is opposite where the
dependencies are missing on Windows and OSX but Linux is fine:
http://bioconductor.org/checkResults/devel/bioc-LATEST/ChemmineOB/.

We realize that the dependencies of the ChemmineOB package creates extra
workload for the Bioc team, and we are extremely grateful for the support
by the Bioc core team. Please let us know if there is anything on our end
that could be done to resolve this and/or to minimize your workload as much
as possible.

Thanks,

Thomas
