Re: [gdal-dev] GDAL 3.9.0beta1 available for testing
No adverse impacts of GDAL 3.9.0 beta1 on reverse dependency checks of 935 R packages depending on R packages sf and/or terra, both linking to GDAL. I had to wait a bit to transition to Fedora 40, gcc 14.0.1, and R 4.4.0 released yesterday, but all good as far as I can tell.

Re: [gdal-dev] Build static GDAL-Lib and static GDAL-Apps
You may find the listings used to build static libraries for R Windows packages using MXE as the basis to be helpful: https://svn.r-project.org/R-dev-web/trunk/WindowsBuilds/winutf8/ucrt3/toolchain_libs/mxe/src/ These are targeted at Windows, but the dependency tree logic should be similar. In building the successive static libraries, very likely the link order will matter too, so some patience is needed.

Reading both into R shows that the input GRIB data and the GTiff data converted
by gdal_translate are identical.
By the way, better to use the terra package directly, raster uses it indirectly.
Hope this clarifies,

Re: [gdal-dev] GDAL Maintainers Meeting Minutes
Unfortunately, upgrading to 3.0.1 failed in October: https://bugzilla.redhat.com/show_bug.cgi?id=2166459. I hope my (duplicate) report may nudge the build team.
