Hi Sue, I maintain a few static libs for R packages on https://github.com/rwinlib. If your R packages are open source I can try to add the libraries you need. Answers inline:

Yes, but usually you'll need msys to as well to run configure, etc. > MSYS2 is very convenient for compiling many of these libraries. Can a > static library compiled with x86_64-w64-mingw32 (gcc 4.9.2) be used with > Rtools33 (v 4.6.2)? Sometimes. It will not work for c++ libraries because the gcc build included with msys2 uses a different exception and threading models. For C libraries, sometimes building in msys2 leads the static library to depend on certain system libraries that are included with msys2 but not with rtools. > Can a static library compiled using x86_64-w64-mingw32-gcc > cross-compiler (v 4.6.2) on linux be used with Rtools33? If the library is built properly, this is usually not a problem; most builds do not depend on a particular gcc version. For example static and dynamic libraries for libcurl and dependencies (openssl, libssh2, libz, etc) are available via http://curl.haxx.se/gknw.net/7.40.0/ and in my experience these can be linked with any somewhat recent version of gcc. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
