We’re using passenger and nginx combo for our Rails application at production environment. After upgrading passenger to 5.0.26, We’re seeing errors from passenger about building the native support so file.

{% highlight ruby %} App 14490 stderr: [passenger_native_support.so] trying to compile for the current user (deploy) and Ruby interpreter… App 14490 stderr: (set PASSENGER_COMPILE_NATIVE_SUPPORT_BINARY=0 to disable) App 14490 stderr: Warning: compilation didn’t succeed. To learn why, read this file: App 14490 stderr: /tmp/passenger_native_support-%@$#^^.log App 14490 stderr: [passenger_native_support.so] not downloading because passenger wasn’t installed from a release package App 14490 stderr: [passenger_native_support.so] will not be used (can’t compile or download) App 14490 stderr: –> Passenger will still operate normally. {% endhighlight %}

In the /tmp/passenger_native_support-%@$#^^.log file log, the error looks like:

{% highlight ruby %}

mkdir -p /usr/lib/buildout/ruby/ruby-version-linux

Encountered permission error, trying a different directory…

mkdir -p /home/deploy/.passenger/native_support/5.0.26/ruby-version-linux

cd /home/deploy/.passenger/native_support/5.0.26/ruby-version-linux

/usr/bin/ruby-version /usr/lib/src/ruby_native_extension/extconf.rb

/usr/bin/ruby-version: No such file or directory – /usr/lib/src/ruby_native_extension/extconf.rb (LoadError) {% endhighlight %}

In short, ruby_native_extension isn’t the correct folder, but as a temporary fix to get the compilation going you could just copy the necessary files there anyway, e.g.:

{% highlight ruby %}

sudo mkdir /usr/lib/src/
cp -dpR /usr/share/passenger-enterprise/ruby_extension_source /usr/lib/src/ruby_native_extension

{% endhighlight %}

We moved our machine to Unicorn as we’ve scope to migrate till now.
