Well "it worked me for" but a better approach entirely outside of your package may be to take edd@max:~$ grep shared /etc/R/Makeconf DYLIB_LDFLAGS = -shared -fopenmp# $(CFLAGS) $(CPICFLAGS) SHLIB_CXXLDFLAGS = -shared SHLIB_CXX1XLDFLAGS = -shared SHLIB_FCLDFLAGS = -shared SHLIB_LDFLAGS = -shared# $(CFLAGS) $(CPICFLAGS) edd@max:~$ and add them to ~/.R/Makevars as DYLIB_LDFLAGS = -shared -fopenmp# $(CFLAGS) $(CPICFLAGS) SHLIB_CXXLDFLAGS = -shared SHLIB_CXX1XLDFLAGS = -shared SHLIB_FCLDFLAGS = -shared SHLIB_LDFLAGS = -shared# $(CFLAGS) $(CPICFLAGS) When I do that without/with the change I get edd@max:/tmp/ffstream$ ls -lh ffstream*/src/ffstream.so -rwxrwxr-x 1 edd edd 9.0M Nov 26 07:52 ffstream.orig/src/ffstream.so -rwxrwxr-x 1 edd edd 734K Nov 26 07:52 ffstream/src/ffstream.so edd@max:/tmp/ffstream$ I think it is an issue worth raising with on r-devel and I may do so.
