[R-pkg-devel] Issue with R Package on CRAN - OpenMP and clang17

[Romain Pierlot]

Hi there, 

I'm sorry to disturb, I hope I send a mail at the right place. 





I have been encountering a challenge with an R package that I've been working on, which was recently removed from CRAN due to some issues in Fortran. 

It appears that I have addressed the Fortran issues, but upon resubmission to CRAN, the package was not accepted, and the following error was returned : 


''With clang17 it still fails to install: 

error: loc("/data/gannet/ripley/R/packages/incoming/frailtypack.Rcheck/00_pkg_src/frailtypack/src/Integrale_mult_scl.f90":1811:17): 'omp.reduction' op must be used within an operation supporting reduction clause interface 
error: verification of lowering to FIR failed 

LLVM trunk gives the same error. 
'' 




I have attached the portion of the code where this issue is reported. From my understanding, it appears to be related to parallelization, but I have been unable to resolve it on my own. 

I would greatly appreciate any assistance or advice that you might be able to offer. If you require any additional information, please do not hesitate to let me know. 




Moreover, I don't know if it is normal or not, but when I check my package with R CMD chech --as-cran, I don't have any error or note message. But when I submit the package to the CRAN, they return errors and notes. 








Thank you very much for your time and consideration. 




Best regards, 




Romain Pierlot
