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.

Steve,

That's terrific (and my apologies for doubting your DTrace implementation even for a second)! Was this done by making modifications to your linker or gcc perhaps?

And congratulations to you and your colleagues on the port of DTrace to Mac OS X. We hope to hear from you all much more now that it's in the wild.

Adam
