Dear R-devel list,
I maintain two packages that use Rust code through the "extendr" library: ymd (https://github.com/shrektan/ymd) and fcl (https://github.com/shrektan/fcl) . These packages are currently at risk of being removed from CRAN due to calls to R's non-API functions. I've addressed most of these issues by upgrading to "extendr 0.8.0". When testing with R-win-devel, the packages pass all checks. However, upon submission to CRAN, I'm facing a confusing situation: the packages pass checks on Windows but fail on Debian with the following warning: * checking compiled code ... WARNING File 'ymd/libs/ymd.so': Found '_exit', possibly from '_exit' (C) Object: 'rust/target/release/libymd.a' Found 'abort', possibly from 'abort' (C) Object: 'rust/target/release/libymd.a' Found 'exit', possibly from 'exit' (C) Object: 'rust/target/release/libymd.a' I'm not sure if this is still an issue with extendr or if it's a false warning. I'm particularly puzzled by the discrepancy between Windows and Debian check results. Is there an easy way to check against the Debian win-devel server before resubmitting to ensure these issues are fixed? For reference, here's the relevant excerpt from CRAN's automated email: package ymd_0.1.5.tar.gz does not pass the incoming checks automatically, please see the following pre-tests (additional issue checks): Windows: https://win-builder.r-project.org/incoming_pretest/ymd_0.1.5_20250414_114928/Windows/00check.log Status: OK Debian: https://win-builder.r-project.org/incoming_pretest/ymd_0.1.5_20250414_114928/Debian/00check.log Status: 1 WARNING Any insights or suggestions would be greatly appreciated.
