Subject: [Bioc-devel] R-devel for Windows: Rtools3.5 vs Rtools4.0
Dear Biocore team,
How is Bioconductor handling the transition to the new R for Windows toolchain?
The R-Devel build for Windows currently available from CRAN uses Jerome Oom's new gcc 8.3.0 toolchain from rtools40, whereas R-Devel builds for Windows downloaded from CRAN a couple of months ago used the older rtool35 toolchain.
It appears that the Bioconductor developmental repository is using rtools35, which means that BiocManager::install is incompatible with the R-Devel build for Windows now on CRAN but works with R-Devel from a month or two ago.
When Bioconductor 3.11 is released, will it be the rtools40 toolchain or rtools35?
Thanks
Gordon
