_dtrace_defcpp needs to be changed about linux HOT 5 OPEN

Hello Martin,

thanks for pointing this out. I will make a fix to correct this.

in libdtrace/dt_open.c the default Solaris cpp is used:

const char _dtrace_defcpp = "/usr/ccs/lib/cpp"; / default cpp(1) to
invoke */

which should be changed to the Linux path for cpp (or gcc -E)

I noticed when I tried to compile Ruby 2.0 with DTrace support:
http://github.com/ruby/ruby

I think it is a good test case!

from linux.

I've got a follow-up question from compiling Ruby 2 - any clue as to why probes.o isn't relocatable?

Probably because i am stupid and didnt add the switch?

Another to add to my todo.

Hahaha! Don't worry, you probably just didn't test it - that is not the same as being stupid :)

Let me know if you want help testing...
