Description

On some Linux based platforms, when installing a library using the R CMD INSTALL command, the binaries in the src folder are compiled omitting the -g parameter. The generated shared object for the library is missing debug symbols.

When installing a library using the R CMD INSTALL command on some Linux systems, the binaries in the src folder are built without the -g flag. The result is that debug symbols are missing from the library's created shared object.

When RcppDeepState and, in particular, Valgrind are used to evaluate such a package, the outcome is an empty table from the deepstate_harness_analyze_pkg function.
There appears to be no error, from the fuzz testing analysis. However, a closer look at the resulting XML file reveals some errors found by Valgrind: the problem is that the errors are related to the shared object file rather than the original function.

Fixes #2

Solution

The solution is to override the current Makevars file in order to set the additional pre processor option -g to the compilation procedure run by the R CMD INSTALL command. The right method to accomplish this, as specified on the R project documentation page, is to create Makevars file in the package's src folder before running the installation command.

The function deepstate_pkg_create in the pkg_harness_create.R file in RcppDeepState runs the R CMD INSTALL. The goal of the solution is to intercept this system shell call and produce the Makevars file before the compilation begins.
