Not quite what I meant. You can't "hog" PKG_LIBS as some package use it (eg for RcppArmadillo). Try DYLIB_LDFLAGS = -Wl,-S -shared -fopenmp# $(CFLAGS) $(CPICFLAGS) SHLIB_CXXLDFLAGS = -Wl,-S -shared SHLIB_CXX1XLDFLAGS = -Wl,-S -shared SHLIB_FCLDFLAGS = -Wl,-S -shared SHLIB_LDFLAGS = -Wl,-S -shared# $(CFLAGS) $(CPICFLAGS) instead.
