Trouble installing on Amazon EC2

Coolnesss commented 7 years ago

I'm trying to install nmatrix as part of my Rails build, using Elastic Beanstalk. When i run eb deploy, which deploys the code and runs bundle install, I get

(...)
  Installing nmatrix 0.2.3 with native extensions

  Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

      current directory: /opt/rubies/ruby-2.3.1/lib/ruby/gems/2.3.0/gems/nmatrix-0.2.3/ext/nmatrix
  /opt/rubies/ruby-2.3.1/bin/ruby -r ./siteconf20170121-15040-1utdg3g.rb extconf.rb
  Cannot allocate memory - /opt/rubies/ruby-2.3.1/bin/ruby -r ./siteconf20170121-15040-1utdg3g.rb extconf.rb 2>&1
(...)

Also when i SSH to the server and run gem install nmatrix -v 0.2.3 it hangs forever. Is it possible that my EC2 instance doesn't have enough memory to... compile nmatrix libraries? Any ideas? My instance should have 512MB of RAM.

Are you sure it hangs forever when you do 'gem install nmatrix -v 2.3'? It does take quite a time. Leave it for like half an hour and see if that works.

Hey @lokeshh, thanks for your reply. Indeed, I left it for quite some time now and I managed to get the following error

virtual memory exhausted: Cannot allocate memory
make: *** [storage/yale/yale.o] Error 1

make failed, exit code 2

Does this mean i need to up the memory on my instance?

Does your hard disk have enough space left?

Coolnesss commented 7 years ago

df -h has the following output

Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        488M   56K  488M   1% /dev
tmpfs           498M     0  498M   0% /dev/shm
/dev/xvda1      7,8G  2,9G  4,8G  38% /

Should this suffice for the installation? I think virtual memory refers to swap and RAM combined, so maybe i need to add more swap?

Thanks, solved by adding more swap to my instance.
