mongrel unicorn - May 2012 - unicorn 4 does not compile on Joyent (SmartOS/Solaris) due to raindrops dependency

Dear unicorn developer list,

I did a quick search online and couldn''t find many reports, but I
thought I''d find out anyway.

Joyent cloud is a pretty awesomely fast cloud running on Solaris
derivative (SmartOS). Pretty much the entire ruby stack, including
imagemagick (the perennial nightmare) build without problems with ruby
1.9.3, as does unicorn up until version 3.7.0.

However, the raindrops dependency introduced in 4.0 breaks raindrops
(and therefore unicorn 4) on SmartOS.

The fact that the compilation breaks in the file named
"linux_inet_diag.c" makes me believe that perhaps the authors may not
have anticipated usage beyond Linux, or there may be some other
reason. In any case, it would be great to be able to run latest
unicorn on SmartOS, so if anyone has any suggestion please let me know
how. In the meantime we are running on 3.7.0.

Best regards,
Konstantin

That file is Linux-specific, but the rest of raindrops (and unicorn)
works on FreeBSD, OpenBSD and probably others.  I have every expectation
it''d work on SmartOS[1]

  ^^^^^

Are you running a mixed 32-bit/64-bit installation?
Can you check the build system isn''t picking the wrong compiler
or compiler flags?

That''s odd, the first line is just #include <ruby.h>

You can try emptying/removing that file completely?  (maybe
linux_tcp_diag.c, too).

Your env shouldn''t define the __linux__ macro.  The linux_* files is
wrapped with an #ifdef __linux__, so those files shouldn''t even
be compiled on other OSes.

The portable part of raindrops does use CPU-specific atomics
(which GCC or libatomic_ops provides).  Ruby 1.9.3 itself uses
these instructions, too.


[1] - SmartOS seems to be Free Software, so I can actually support it :)

Eric, awesome and thanks for replying!

I''ll email you privately to chase this down.
