Thanks for working on Solaris. You may well be the only non-member of R Core who does so --- Prof Ripley usually complains to us when Rcpp breaks there, and we usually just shrug our shoulders and point out that our hands are tied: no Solaris machine either one of us can access, so no (meaningful) way to work on fixes. But more recently, Martyn Plummer (CC'ed) provided two excellent patches which helped a lot. With those, we now have Rcpp 0.9.7, and Solaris builds on Prof Ripley's test systems, or at least the x86-based one. Sparc still fails as per the results page linked from CRAN's results page for Rcpp. Now, for the backtrace and backtrace_symbols symbols were not declared. Grep'ing for this I found edd@max:~$ grep -rin backtrace svn/rcpp/pkg/Rcpp/src/* svn/rcpp/pkg/Rcpp/src/debugging.cpp:56: stack_depth = backtrace(stack_addrs, max_depth); svn/rcpp/pkg/Rcpp/src/debugging.cpp:57: stack_strings = backtrace_symbols(stack_addrs, stack_depth); svn/rcpp/pkg/Rcpp/src/debugging.cpp:67: free(stack_strings); // malloc()ed by backtrace_symbols edd@max:~$ and indeed, in debugging.cpp I see #else // ! (defined(WIN32) || defined(__FreeBSD__) || defined(__NetBSD__) || defined(__OpenBSD__) which is lacking a Solaris test -- I may need to add || defined(__SUNPRO_CC) test as well. Could you try locally if that works? Maybe Google can suggest another Solaris variable to test for too? Dirk -- "Outside of a dog, a book is a man's best friend.
