Roger, See if this [1] is what you were asking for. As far as there is a Mac specific session I?ve duplicated some of your statements. Thanks for bringing taht to osGEO Agust?n [1] https://wiki.osgeo.org/wiki/SAC_Shared_Building_Services
Agustin, Thanks very much! This gives a place-holder - how should we "handshake" to OSGeo on this? Adding this mailing list to the wiki is unhelpful for non-subscribers - it would be helpful to identify people to contact. Best wishes, Roger

Please also follow up the grass-dev thread with regard to CI. Following the OSGeo shared building services initiative may help those installing from source on Windows and macOS. If we in addition can promote the provision of reliable static-linkable components, we could perhaps reduce the burden on CRAN, especially if CI could check CRAN compatability of build trains (compiler versions etc.). We would have more leverage if r-spatial in some form became a project associated with OSGeo as well as R itself, as mentioned in the discussion issue. If a list member has edit access to the OSGeo wiki, please add text about r-spatial, for example to "Current State": R Windows binary packages distributed by the Comprehensive R Archive Network (CRAN) using OSGeo software (chiefly PROJ, GDAL and GEOS) use custom built binaries compatible with the build train used by R and are static linked; at present both 32-bit and 64-bit binaries are deployed. CRAN packages for macOS are also static linked to custom built binaries, again using the build train used by R. Static linkage is used to avoid having to deploy a package manager for external software on which R packages depend, since CRAN as a package manager already supports over 15000 packages with three binary versions (devel, release, old release) for Windows and macOS. Please report back here if you are able to enter this text or similar, or are in touch with the site admin. Contributions very welcome!
