I just built Poly/ML from the latest sources in SVN on Mac OS X 10.8.4 and got the following warning:
/bin/sh ./libtool --tag=CC --mode=link gcc -DMACOSX -Wall -fno-strict-aliasing -O3 -I../libffi/include -o poly polyexport.o libpolymain/libpolymain.la libpolyml/libpolyml.la -lpthread -lm -ldl -lstdc++ -lgcc libtool: link: gcc -DMACOSX -Wall -fno-strict-aliasing -O3 -I../libffi/include -o poly polyexport.o libpolymain/.libs/libpolymain.a libpolyml/.libs/libpolyml.a -lpthread -lm -ldl -lstdc++ -lgcc ld: warning: could not create compact unwind for _ffi_call_unix64: does not use RBP or RSP based frame ld: warning: PIE disabled. Absolute addressing (perhaps -mdynamic-no-pic) not allowed in code signed PIE, but used in area1 from polyexport.o. To fix this warning, don't compile with -mdynamic-no-pic or link with -Wl,-no_pie
I don't have any problems running Poly/ML after this, but I wondered if it was something that somebody somewhere might care about.
Regards,
Rob.
