failed to load rcdk

[fdq09eca]

I am on a M1 BigSur. I have no problem in loadingrJava but it seems rcdklibs has not been load properly when I load rcdk.

> library("rJava")
> library("rcdk")
Loading required package: rcdklibs
zsh: trace trap  R

Here is my java version

Unfortunately, I don't have access to an M1 setup to test this on.

Are you using the latest code from Github?

Hi @rajarshi, I can reproduce this error on a Windows 10 with current R-Studio running (same on Windows Server 2019). The error is not reproducible in the native R-GUI and thus maybe related to any interaction with R-Studio.

I run the latest versions of rcdk and rcdklibs installed from GitHub.

I dug a little deeper. There is obviously a rJava / RStudio bug in R4.20. A patch for Windows is available. See https://community.rstudio.com/t/problems-with-rjava-in-rstudio/135896.
