Hi everyone,

Trying to deploy an app to shinyapps.io, but installation of one of the required libraries (symengine, https://github.com/symengine/symengine.R) fails with the following trace:

Can someone suggest where to start troubleshooting? Works fine on my local Windows 10 64-bit R 4.0.3 instance, and deployment worked OK for an earlier version of the app which also included symengine (late last year).

Update: have tried both fresh GitHub version and CRAN binary (locally) - no luck.

Is this normal? (From the deploy log)

The libudunits2 comes from the units packages.

Perhaps you need to install the symengine required dependencies in ubuntu?

Hi @justinwilkins, I am one of authors of symengine. The package would require cmake as one of the system dependencies (see the DESCRIPTION file). Seems shinyapps.io didn't preinstall that.

I created a request at https://github.com/rstudio/shinyapps-package-dependencies/issues/268
