Dear list, I'm having trouble reproducing errors from CRAN's pretests.
I have a package on CRAN called epanet2toolkit that provides R bindings to a legacy simulation engine written in C. So far I've released two versions to CRAN without trouble. Now I'm making a third release, principally to include a citation for the package, but also to clean up warnings raised by new compilers. My latest submission fails the CRAN pretests for Debian with errors in the examples and tests: https://win-builder.r-project.org/incoming_pretest/ epanet2toolkit_0.3.0_20180726_102947/Debian/00check.log For what it's worth, the package checks fine under R-3.4.4, R-3.5.0 and R-devel r74997 (2018-07-21) and r74923 (2018-06-20). However, when I run the debian-r-devel checks locally (albeit in Docker) I get a couple of warnings, but no errors. Since I can't reproduce the error, it's difficult to fix. See below the relevant lines of 00check.log: * using log directory ‘/pkg/epanet2toolkit.Rcheck’ * using R Under development (unstable) (2018-07-25 r75006) * using platform: x86_64-pc-linux-gnu (64-bit) * using session charset: UTF-8 * using option ‘--as-cran’ * checking for file ‘epanet2toolkit/DESCRIPTION’ ...
