0.10.0 build failed on mac os about ruby-pg HOT 9 CLOSED

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

Can you also attach or paste your mkmf.log? That will have the specifics as to why it can't find the libpq-fe.h header.

Thanks!

PS: while I do all of my development on a Mac, I haven't tested this under 1.9.1 since 1.9.2 came out. I doubt that's the issue, however.

i don't know why 1.9.1 in path, but i use ruby 1.9.3

ruby -v output:

ruby 1.9.3dev (2010-11-20 trunk 29843) [x86_64-darwin10.5.0]

P.S. using ruby 1.9.2 i got same error. and strange 1.9.1 in path too - "/Users/user/.rvm/rubies/ruby-1.9.2-p0/lib/ruby/1.9.1/mkmf.rb"

Oh, right, I forgot that 1.9.2 uses the 1.9.1 library path; I don't know why, but that's normal. Thanks for the log.

I think the problem is that your libpq is compiled as a universal binary (with three architectures) and your Ruby is compiled without at least one of them. If you do a file which ruby``, it should show which architectures your Ruby supports, and you'll have to either reinstall PostgreSQL with only those architectures, or your Ruby with all three that your Postgres supports.

For example, my system Ruby says:

$ file `which ruby`
/usr/bin/ruby: Mach-O universal binary with 3 architectures
/usr/bin/ruby (for architecture x86_64):	Mach-O 64-bit executable x86_64
/usr/bin/ruby (for architecture i386):	Mach-O executable i386
/usr/bin/ruby (for architecture ppc7400):	Mach-O executable ppc

while my rvm-installed 1.9.2 says:

$ rvm 1.9.2
$ file `which ruby`
[...]/.rvm/rubies/ruby-1.9.2-p0/bin/ruby: Mach-O 64-bit executable x86_64

The clue is in the linker phase from the mkmkf.log:

lipo: can't figure out the architecture type of: /var/folders/DR/DR5qjIGGEWiVOvkRtZ5u3E+++TI/-Tmp-//ccqYG1Im.out
checked program was:
/* begin */
1: #include "ruby.h"
2: 
3: int main() {return 0;}
/* end */

That's why I put that warning in the extconf that says:

*** Your PostgreSQL installation doesn't seem to have an architecture in 
common with the running ruby interpreter (["ppc", "i386", "x86_64"] vs. [])
I'll continue anyway, but if it fails, try setting ARCHFLAGS.
  testing for architecture: "ppc"
  testing for architecture: "i386"
  testing for architecture: "x86_64"

I haven't compiled postgres by myself, i downloaded binary. seems like only one way to fix it is compile ruby as universal binary or set ARCHFLAGS='-arch x86_64' before installing pg gem.

Even setting the architecture yourself won't work, as it won't be able to link completely due to the missing architectures. If you want to use the installation of PostgreSQL you're currently using, the only way (that I know of) is, as you say, to compile Ruby with the same three architectures that your Postgres supports.

setting archflags helped. at least gem installed successfully and it works.

Oh, good! I didn't think you could link that way, but I stand corrected. Thanks for trying, and especially for reporting that it worked. :)
