Hi,
I'm trying to make the pcap gem work on Rubinius. That gem uses the
trapping mechanism (TRAP_BEG/TRAP_END) from the 1.8.7 API, which
Rubinius does not provide; instead, there's the
rb_thread_blocking_region call from the 1.9 API. Now things get
complicated, since Rubinius announces RUBY_VERSION 1.8.7, so I cannot
use the version string for disambiguation.
For now, it seems to be possible to use the (rbx-specific) RUBY_ENGINE
constant, but that's not defined in MRI 1.8.x. What I'm doing in
extconf.rb right now is:
begin
if RUBY_VERSION =~ /^1\.9\./ or RUBY_ENGINE == "rbx"
cflags << '-DHAVE_1_9_THREAD_API'
end
rescue NameError
# ignore errors trying to accept RUBY_ENGINE
end
It would be nice if rbx provided the TRAP_* macros like MRI does, at
least as long as it announces version 1.8.
