In Postgres we follow the old way of implementing USDT. 1) add probes to src.c 2) cc -c src.c -o src.o 3) dtrace -G -s probes.d src.o ... 4) cc -o postgres src.o probes.o This works fine on Solaris but it breaks on OSX since the -G flag doesn't exist (adding it with no-op won't help). Can this still be done in OSX (replacing -G with -h?) or does it only support the new way where the .h file has to be produced first? If not, I'd say the two implementations have incompatible behavior. -Robert _______________________________________________ dtrace-discuss mailing list dtrace-discuss@opensolaris.org
