[Bioc-devel] arm64 on Mac build fails due to problem with MPO.db

[Matteo Tiberti]

Dear all,

We are seeing a couple of build fails of our MoonlightR and Moonlight2R packages in the devel (3.18) MacOS arm64 builder that seem to be related to the MPO.db package. This is the error message we get:

* installing to library ‘/Library/Frameworks/R.framework/Versions/4.3-arm64/Resources/library’
* installing *source* package ‘Moonlight2R’ ...
** using staged installation
** R
** data
** inst
** byte-compile and prepare package for lazy loading
Warning: Couldn't set cache size: file is not a database
Use `cache_size` = NULL to turn off this warning.
Warning: Couldn't set synchronous mode: file is not a database
Use `synchronous` = NULL to turn off this warning.
Error: .onLoad failed in loadNamespace() for 'MPO.db', details:
  call: NULL
  error: file is not a database
Execution halted
ERROR: lazy loading failed for package ‘Moonlight2R’
* removing ‘/Library/Frameworks/R.framework/Versions/4.3-arm64/Resources/library/Moonlight2R’

We don’t have MPO.db as an explicit requirement for our packages, and it checks all green on its own build report. We poked around 3.18 MacOS arm64 build reports and saw several other packages with similar failures (e.g. miRspongeR<https://bioconductor.org/checkResults/3.18/bioc-mac-arm64-LATEST/miRspongeR/> miRSM<https://bioconductor.org/checkResults/3.18/bioc-mac-arm64-LATEST/miRSM/> MicrobiomeProfiler<https://bioconductor.org/checkResults/3.18/bioc-mac-arm64-LATEST/MicrobiomeProfiler/> EasyCellType<https://bioconductor.org/checkResults/3.18/bioc-mac-arm64-LATEST/EasyCellType/> MetaPhOR<https://bioconductor.org/checkResults/3.18/bioc-mac-arm64-LATEST/MetaPhOR/> meshes<https://bioconductor.org/checkResults/3.18/bioc-mac-arm64-LATEST/meshes/> CBNplot<https://bioconductor.org/checkResults/3.18/bioc-mac-arm64-LATEST/CBNplot/> …) so we were wondering if there’s a more general problem with the builder/set up or if there is a general solution to this. Suggestions are welcome

Thank you,
