Unable to install strex package using gcc version 4.4.7

[JordaneGourlay]

I am unable to install strex package using these two installations :

sessionInfo()
R version 3.3.1 (2016-06-21)
Platform: x86_64-koji-linux-gnu (64-bit)
Running under: CentOS Linux 7 (Core)

sessionInfo()
R version 3.3.1 (2016-06-21)
Platform: x86_64-koji-linux-gnu (64-bit)
Running under: Scientific Linux release 6.8 (Carbon)

Both having as GCC version "4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)"

I am getting these warnings

stringi-imports.h: In function ‘C_stringi_replace_all’:
stringi-imports.h:10:5: warning: implicit declaration of function ‘R_GetCCallable’ [-Wimplicit-function-declaration]
     R_GetCCallable("stringi", "C_stri_replace_all_coll");
     ^

     INTEGER_GET_REGION(int_prlst_i_car, 0, nr, out_int + i * nr);

Which leads me to the following error

** testing if installed package can be loaded
Error in dyn.load(file, DLLpath = DLLpath, ...) :

It seems that your version of R is too old. I wasn't aware of this, but it seems that a C function that I was using INTEGER_GET_REGION() came with the ALTREP framework which is from R 3.5. Can you update your R to 3.5 or later?

[JordaneGourlay]

Thanks for your fast answer. We are currently having to POC to enhance our version of GCC so we can upgrade our R version but can't do it for now. I think you should update dependencies of your package on CRAN (currently they are written as R (≥ 3.1), stringr (≥ 1.4)).

Yes you are right. I will do that today thank you 😊
