passenger-config build-native-support

[Jay Howard]

I'm attempting to build native support for ruby 2.2.4 on Centos6 w/ Passenger 5.0.30 (from repo, not gem).  Applications is Rails under Apache.

When I run "passenger-config build-native-support" I get a failure that directs me to a log file, which contains:

# current user is: root
# mkdir -p /root/.passenger/native_support/5.0.30/ruby-2.2.4-x86_64-linux
# cd /root/.passenger/native_support/5.0.30/ruby-2.2.4-x86_64-linux
# /usr/local/rvm/gems/ruby-2.2.4/wrappers/ruby /usr/share/passenger/ruby_extension_source/extconf.rb
checking for alloca.h... *** /usr/share/passenger/ruby_extension_source/extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

I also tried running passenger-config as the user our application runs under, but the result was the same.

The file alloca.h exists where I'd expect it to, i.e. /usr/include.

Also, when I manually cd to "/root/.passenger/native_support/5.0.30/ruby-2.2.4-x86_64-linux" and run "/usr/local/rvm/gems/ruby-2.2.4/wrappers/ruby /usr/share/passenger/ruby_extension_source/extconf.rb" it completes successfully and a Makefile is generated.

Any thoughts?

I notice that pre-built extensions are available for Ruby 2.2.3 here:

https://oss-binaries.phusionpassenger.com/binaries/passenger/by_release/5.0.30/

...but not for Ruby 2.2.4.  Given I'm not able to build them myself, any idea when pre-built extensions will be available for Ruby 2.2.4?

we'll likely make more prebuilt extentions around the time that we release the next update to passenger. Can you dump your shell's env vars? there's clearly some difference between the build environment that is used and what you have your shell set to.

[Jay Howard]

Log follows.  After I run "passenger-config build-native-support" and it fails, I can manually go into the directory where it tries to create the Makefile and run the exact same command ("/usr/local/rvm/gems/ruby-2.2.4/wrappers/ruby /usr/share/passenger/ruby_extension_source/extconf.rb"), and it works.  I can then run make + make install to install the shared lib.

Your env looks normal. I just created a fresh CentOS VM and installed rvm, ruby 2.2.4, passenger and the native extensions without any issue. So I'm not sure what's going on here.

One difference (though this shouldn't matter in practice) is that I wasn't running passenger when I built the native support, another possibly more important detail is that I had added my user to the wheel group.

It's also possible that there is some problem with your g++ install, because the specific failure is that the compiler either failed or doesn't exist.

What is the output of re-running

sudo yum install -y curl gpg gcc gcc-c++ make

If gcc/g++ were missing or mis-configured then I would expect "make" to fail when I run it manually.

Possibly some bug in "mkmf"?  That's used by /usr/share/passenger/ruby_extension_source/extconf.rb.  Looks like it's calling "have_header()" to check for the existence of alloca.h, which is what's failing.

[Jay Howard]

Notably, also:

[jhoward@myhost ~]$ irb
2.2.4 :001 > require 'mkmf'
 => true
2.2.4 :002 > have_header("alloca.h")
checking for alloca.h... yes
 => true

[Camden Narzt]

If you trace /usr/local/rvm/rubies/ruby-2.2.4/lib/ruby/2.2.0/mkmf.rb from line 456 the "The compiler failed to generate an executable file. (RuntimeError) You have to install development tools first." message is generated because have_devel? fails, and if you trace that back to line 528 try_link0 tries to create a temp dir in order to test the linker, it may be that is what's failing and the alloca.h message is a red-herring.

In any case we're going to create new binaries soon, so this issue will go away at that point.
