pg 0.10.0 fails to compile on OpenSolaris about ruby-pg HOT 11 CLOSED

Original comment by Michael Granger (Bitbucket: ged, GitHub: ged).

Something about the way the extconf.rb combines the compilation flags from Ruby and Postgres isn't working, it would appear. It's causing trouble on other platforms as well, so I'm thinking I'll remove it and release 0.10.1 with a simpler extconf.

Hi Michael,

Thanks for the update. Ping me when you'd like me to give this a shot.

I've been trying without success to get PostgreSQL 8.4 installed on OpenSolaris so I can test this myself (I'm fairly clueless about Solaris administration), but I'll give up for now and just ask that you try out the prerelease of 0.10.1 I just pushed to rubygems.org:

gem install pg --pre -v 0.10.1pre209

Once we get this resolved, would you mind lending me your advice on adding an OpenSolaris environment to my bevvy of VirtualBox testing machines? I try to install and run the specs on as many environments as possible, and this is one I don't yet have.

Thanks for your help!

A bit more detail...

The relevant portion of the mkmf.log is this:

The two lines with the '>>>' are the clues.

The two strategies for compiling the test program are both apparently giving the compiler flags it doesn't understand. With version 0.10.0, I introduced a change to the extconf that added the compiler flags specified by pg_config to those used to compile 'pg', but that caused more problems than it solved, so I backed that change out for 0.10.1.

I'm guessing that the problem under OpenSolaris is that PostgreSQL is built using a different compiler than Ruby is, resulting in the unrecognized options.

Hey Michael,

Thanks so much for looking at this. I will try out the gem in the next couple of days. As for helping with OpenSolaris install, I'm actually quite new to it. I'll need to have a coworker help me, then I can help you. :-)

I will give you an update as soon as I can.

Thanks again!

No problem. I've been talking to a former co-worker of mine who's a Solaris admin, and he's been trying out the newer gems for me. We haven't been able to duplicate your results, but I at least verified that the newest gem installs okay in his environment.

I wanted to push out 0.10.1 to fix a few other problems, but hopefully this will resolve any issues under Solaris as well.

Michael,

Been a crazy couple of weeks. I can confirm that 0.10.1 is able to install and function on our OpenSolaris install.

Thank you so much for all your help on this!

Hi,

This didn't work on Mac OS X 10.6.6 with latest XCode. I get the same failure as described above.

Thanks

Are you sure it's not more like #57?

99% of the time, when someone reports a problem installing the library under OSX, it's because they're installing 'pg' with a universal Ruby binary compiled against a non-universal PostgreSQL. See the instructions in [[https://bitbucket.org/ged/ruby-pg/src/8ab3dd3c757b/README.OS_X|README.OS_X]] for how to resolve this.
