Interesting. Although, LDSHARED is defined like this in config/Makefile: LDSHARED= $(CC) -bundle -undefined dynamic_lookup $(LDFLAGS)
so you'd think setting LDFLAGS wouldn't affect those initial flags. - Josh On 2013-5-3 12:07 , Michael Dickens wrote: > In my recent (still not fully tested and hence not yet checked in) work > with numpy and scipy, to get +universal working robustly, I have to > manually set env LDFLAGS="-undefined dynamic_lookup -bundle", and also > be careful with the other *FLAGS (e.g., CFLAGS, CPPFLAGS, CXXFLAGS, > F2CFLAGS, ...).
