Dear R package developers I am getting the following errors in my package (sundialr - https://github.com/sn248/sundialr) which is a wrapper around SUNDIALS C library. The warnings are as follows:
❯ checking compiled code ... > WARNING File ‘sundialr/libs/sundialr.so’: > Found ‘abort’, possibly from ‘abort’ (C) Object: > ‘../inst/lib/libsundials_core.a’ > Found ‘puts’, possibly from ‘printf’ (C), ‘puts’ (C) Object: > ‘../inst/lib/libsundials_core.a’ > Found ‘stderr’, possibly from ‘stderr’ (C) Object: > ‘../inst/lib/libsundials_core.a’ > Found ‘stdout’, possibly from ‘stdout’ (C) Objects: > ‘../inst/lib/libsundials_core.a’, ‘../inst/lib/libsundials_cvodes.a’, > ‘../inst/lib/libsundials_idas.a’, ‘../inst/lib/libsundials_nvecserial.a’ > Compiled code should not call entry points which might terminate R nor > write to stdout/stderr instead of to the console, nor use Fortran I/O nor > system RNGs nor [v]sprintf. See ‘Writing portable packages’ in the ‘Writing > R Extensions’ manual. See them at - https://cran-archive.r-project.org/web/checks/2025/2025-05-12_check_results_sundialr.html As far as I understand these warnings are coming from the following files: 1. 'abort' coming from - https://github.com/sn248/sundialr/blob/ace6865ac0bc995190bc4c354a8823ea8d3bd358/src/sundials/sundials/sundials_errors.c#L87 2. I cannot find the file/line where 'puts' is coming from 3. stderr/stdout -- too many instances in SUNDIALS C code to list here, e.g., https://github.com/sn248/sundialr/blob/ace6865ac0bc995190bc4c354a8823ea8d3bd358/src/sundials/arkode/arkode.c#L1285 In principle, I don't want to change anything in the upstream C library code while including it in my package. Is this any other way to resolve these warnings as the package has been archived because of these warnings now.
