There may well be an error on your end: What made you think it would work with static libraries? Dynamic linking all the way. | 2) There isn't a method called update in the version of the class Language in | /usr/local/lib/R/site-library/Rcpp/include/Rcpp/Language.h | | These observations lead to the natural questions: | | 1) are you sure the distributed LibRInside.a was compiled with the latest | version of the class Language? "distributed LibRInside.a" ? Fist off, you have the capitalization wrong. Second, how am I supposed to know how YOU built this? I ship SOURCES. You control your builds. There is no distributed libRInside.a, only sources and a Makefile. This is R. It has _fixed recipes:: We say R CMD INSTALL. We control how it works. | 2) When you say that everything works fine there, did you consider linking | against each one of the THREE version of libRInside: /lib/libRInside.a, / | lib/libRInside.so and | /libs/libRInside.o? I ship a Makefile. I say 'make'. It works. Follow the (free) tools I give you. If you insist of revinvention your builds and things break, well then you get to keep the pieces.
