Hello, all members.

I'm studying R programming because of simulation analysis.

I'm compiling c file for making .o and .dll files.

But I have some problem regarding compiling error.

The problem is as follow.

----------------- R code Input command for compiliing c file--------------------------------

D:\kyuri_kim\CiPA\CiPA_Rocde\CiPA-master\AP_simulation\models>R CMD SHLIB newordherg_qNet.c

------------------The error occurred aftering compiling in rstudio---------------------------

I'm using tools such as R 4.0.0 and Rtools40 in Windows 10 (64bit).

I already check tips Rtools installation and setting using reference as follows. https://cran.r-project.org/bin/windows/Rtools/ https://github.com/r-windows/docs/blob/master/faq.md#readme

Do you know how to solve above error?
