dtrace discuss - Jun 2006 - Including C headers

I''ve tried including some of our C headers to trace certain structures
within the system.  The D (pre?)compiler seems to be having trouble with C++
style comments and fails with a syntax error.

Is there a way to set the compatiblity flags to allow inclusion of C source with
C++ style comments?

Thanks.

There is no built-in option to support this.  If you need to do it, create
a simple cpp wrapper script like this to call cpp -B (strip C++ comments):

#!/bin/sh
exec /usr/ccs/lib/cpp -B "$@"

and chmod +x that.  I saved mine to /home/mws/c++cpp.  Then run dtrace like so:

$ dtrace -C -xcpppath=/home/mws/c++pp -s script.d
