Invalid arch flags on Snow Leopard cause compilation issues

[dbussink]

This line: "#{RbConfig::CONFIG['CFLAGS']} #{$CFLAGS}".split(" ").uniq.join(" ").gsub("$(cflags)", "").gsub("ppc", "")

results in the following line for Snow Leopard: gcc -arch i386 x86_64 -g -Os -pipe -fno-common -DENABLE_DTRACE

This is not valid, because it has to be -arch i386 -arch x86_64 in order to compile it for both architectures. With these flags, the compilations fails with the following error:

i686-apple-darwin10-gcc-4.2.1: x86_64: No such file or directory

Try the latest master.

Cool, this fixes it :)

I'm having problems compiling on the old Leopard myself;

[evan]

What a mess. The arch flags are taken from your Ruby build...how did it get compiled? Can you figure out how to disable -save-temps and -M options (or what they do?)

[morten]

It fails on Leopard for me too - 0.17.5 works nicely. The full output: http://gist.github.com/245153 - looks like make is choking early on?

[evan]

Try v. 0.17.7.

Using macports ruby 1.8.7, I tried this last night on my Snow Leopard machine and it installed perfectly, but install fails on Leopard (10.5) using macports ruby 1.8.7

0.17.7 worked for me, thanks!

[evan]

Spovich, I use that same OS/macports/etc. Can you dig in a little bit more to figure out what flag or option is making the build fail?

[spovich]

I'd love to help, but I'm not sure where to start...

I noticed that I can install macports libmemcached fine on my Snow Leopard box, but again, on my Leopard box, libmemcached install fails.

So maybe my enivronment is messed up on the Leopard box?

I've been wanting to upgrade my Leopard box to SL, so maybe I'll just do that.

Thanks, John

[spovich]

Wow, so I upgraded to SL and it is still failing on that machine. So, I guess I need to roll up my sleeves. Definitely something wrong with that specific machine since it works on my other SL machine...

[spovich]

Got it working now. EBKAC. I had created a shortcut for restarting apache called 'ar' a few months ago which was in my bin directory which is first in my path and hadn't caused any problems until now. This caused the libmemcache build to fail in a very unclear way. I wasn't aware of the real 'ar' command! Lesson learned!
