It's especially odd that they've chosen to support the -h option, but not the -G option -- I'm not to what purpose one could put the generated header file. Perhaps the Apple folks could comment?
The Mac OS X "dtrace -h" emits all the information required for successfully linking a USDT probe by the rest of the toolchain. On Mac OS X "dtrace -G" is superfluous. For historical reasons "-G" was disabled early on in the bring up. We'll take a bug to re-introduce "- G" as a no-op with a warning message.
See the section "BUILDING CODE CONTAINING USDT PROBES" in the Leopard dtrace(1) man page.
Static probes work very nicely on Mac OS X (thank you!) A number of our frameworks ship with "Is Enabled" static probes in Leopard.

Anyone know why -G flag is not supported in the Dtrace port in Leopard? This makes the dtrace cmd in Leopard incompatible with that on Solaris, and it's already causing problem with PostgreSQL.

The following bug has been logged online:
Bug reference: 3699 Logged by: Lee Packham Email address: lpackham at gmail.com PostgreSQL version: 8.2.5 Operating system: OSX Leopard Description: Fails to compile DTrace Support Details:
I have built a patch to enable a working DTrace on OSX with Postgres 8.2.5. Basically the problem is that the dtrace command on OSX doesn't have the -G parameter - so you have to use the newer -h method to produce a header file.
I have put the patch on my blog.

Hope this is of use to you guys.
Cheers,
Lee Packham
