Bug #8606: compile with --enable-dtrace fails with dtrace version SUN D 1.11
https://bugs.ruby-lang.org/issues/8606#change-40326

Author: sax (Eric Saxby)
Status: Open
Priority: High
Assignee: nobu (Nobuyoshi Nakada)
Category: build
Target version: 
ruby -v: 2.0.0-p247
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


When compiling Ruby 2.0 with --enable-dtrace on platforms with dtrace version SUN D 1.11 (for example, SmartOS with platform image joyent_20130521T084103Z or greater), the compile fails just after linking miniruby. The compile fails on linking dtrace symbols, as they are missing.

The problem is that in dtrace 1.11, the compiler was changed to fail if no probes are found. configure runs a test to check whether dtrace -G is needed, I believe because OS X does not need it.

https://github.com/ruby/ruby/blob/1c0abbf07692b21835f6c81f759b8d2d6b8963c2/configure.in#L536-L539

On newer dtrace, this results in the following error:
"dtrace: failed to link script conftest_provider: No probe sites found for declared provider"

So configure incorrectly determines that dtrace -G is not needed, and compilation fails.

From the #smartos irc channel on freenode:
rmustacc: So, the most correct solution would be to use the probe from the header file in the conftest.o that they try and run dtrace -G on.
