Well "it worked me for" but a better approach entirely outside of your
package may be to take
edd at 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) $(CPICFLAGS)
edd at max:~$
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) $(CPICFLAGS)
When I do that without/with the change I get
edd at max:/tmp/ffstream$ 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 at max:/tmp/ffstream$
I think it is an issue worth raising with on r-devel and I may do so.
Dirk
