I have been trying to build an R package that uses C code. I was not fast enough to get a working build for some time as it is a wrapper package around an existing C library and I wanted to submit to CRAN eventually, so I needed to get a linux and windows (32 and 64-bit) builds working correctly. Building an R package even with native R code is not easy.There are a lot of intricacies for a “software-developer by necessity” like me to learn and it is definitely not idiot-proof. I will try to write a few posts on this journey.
