That sounds like a show stopper to me. We certainly don't want to have to rebuild third party libraries. But two things are not clear to me 1) Is it just libraries using C++ that are affected or also libraries using only C? 2) What happens if you don't rebuild the library? > - A package (Rgraphviz) failed because of a line in Makevars.win: > gcc.exe: error: unrecognized command line option > '-WI,--enable-auto-import' > removing the line: > PKG_LIBS += -WI,--enable-auto-import > fixed the problem That one is just a typo. To pass an option (e.g. --enable-auto-import) to the linker one should use -Wl not -WI. So it is good that the new tool chain is picking this up.
