ruby19 @1.9.2-p290

[joshuajmoody@…]

System Information: Lion 10.7.2 and Xcode 4.2

I ran into trouble installing ruby19.

:info:configure checking whether the C compiler works... no
:info:configure configure: error: in `/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_ruby19/ruby19/work/ruby-1.9.2-p290'                                                                                                                                                                                      
:info:configure configure: error: C compiler cannot create executables

Looking at the Portfile, I found this:

# ruby-1.9.x built with clang or llvm-gcc does not work

      }   
}                                                                                                                                                                            }  

I read the information in the link provided in the comment and decided to try to compile with clang.

I was able to successful build ruby19 and subsequently rb19-rails by commenting out the compiler if conditional.

Can the maintainer please investigate and update the Portfile as necessary?

Thanks!

log file of failed ruby19 build

[ryandesign (Ryan Carsten Schmidt)]

The comment says "ruby-1.9.x built with clang or llvm-gcc does not work", and you only said you were able to build it. Were you actually able to run it also?

[ryandesign (Ryan Carsten Schmidt)]

Also, it might help to diagnose your earlier build failure if you attach the config.log. It looks like MacPorts selected the "Mac OS X gcc 4.2", which I would not have expected, given that you have Xcode 4.2, which does not include any version of gcc.

I am able to run ruby19. I installed rb19-rails and was able to stand up a demo rails site on my machine.

Also, it might help to diagnose your earlier build failure if you attach the config.log.

I did a clean install of MacPorts 2.0.3 in an alternative location. I have attached a config.log and a main.log for a failed ruby19 build. I have also attached the main.log for the successful ruby19 build (halted during the port staging phasing)

It looks like MacPorts selected the "Mac OS X gcc 4.2", which I would not have expected, given that you have Xcode 4.2, which does not include any version of gcc.

This machine has previously had Xcode 3.*, Xcode 4.0, and Xcode 4.1 installed on it. For a time it had both Xcode 4.1 and 4.2 installed.

Here is some information about gcc-4.2 on my machine:

moody% ls -al `which gcc-4.2`
-rwxr-xr-x  1 root  wheel  113024 May 16 05:37 /usr/bin/gcc-4.2
moody% gcc-4.2
gcc-4.2: error trying to exec '/usr/bin/i686-apple-darwin11-gcc-4.2.1': execvp: No such file or directory

Do you require other information?

Thanks for looking into this.

build success does not mean the built ruby works fine. some features, such as thread/fiber, does not work on clang/llvm-gcc ruby.

see ​https://github.com/wayneeseguin/rvm/issues/399

we can test ruby by the following commands.

% sudo port -k install ruby19   # install and keep work directory
% cd `port work ruby19`/ruby-1.9.2-p290
% sudo chown -R ${USER} .       # let work directory writable
% make test                     # basic tests. should pass all tests
% make test-all                 # deeper tests. may fail with some errors, but no segmentaion fault.

results on my Mac.

• Snow Leopard + gcc (Xcode 4.0):
  • make test => pass all
  • make test-all => pass all
• Lion + gcc (Xcode 4.1):
  • make test => pass all
  • make test-all => 2F
• Lion + llvm-gcc:
  • make test => Bus Error (segmentaion fault)
• Lion + clang:
  • make test => Bus Error (segmentaion fault)

`make test' ruby built with Xcode-4.2 clang

ruby-1.9.3 supports Xcode-4.2 clang. I updated port:ruby19 to 1.9.3-p0 and solved this problem.

thanks all!
