The UBSAN error:
cvode.cpp:58:11: runtime error: call to function
cv_Roberts_dns(double, Rcpp::Vector<14, Rcpp::PreserveStorage>)
through pointer to incorrect function type 'Rcpp::Vector<14,
PreserveStorage> (*)(double, Rcpp::Vector<14, PreserveStorage>)'
note: cv_Roberts_dns(double, Rcpp::Vector<14, Rcpp::PreserveStorage>)
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior cvode.cpp:58:11 in
sounds like it might be a false positive, since the function
signatures do appear to be identical. Of course, there may be
something more subtle going on, but absent any other ill effects I
think the message can be ignored. For what it's worth, one similar
false positive is reported here at
The actual compilation error you're seeing on Solaris:
mksh: Fatal error in reader: = missing from replacement macro reference
implies that you're likely trying to use a GNU-ism in your Makefile /
Makevars. R requires that Makefiles be portable by default, as per
If you _really_ need the GNU-isms, you can add something like:
SystemRequirements: GNU make
to request that GNU make is used on all platforms your package is built on.
