require': libsndfile.so.1: cannot open shared object file

[dhruvg]

I can use ruby-audio perfectly fine on my dev machine (mac os x lion). However, on amazon ec2 (rhel), after bundle installing the gem successfully, I get the following error when trying to start my app:

/usr/local/rvm/gems/ruby-1.9.3-p194/gems/ruby-audio-1.6.1/lib/ruby-audio.rb:6:in require': libsndfile.so.1: cannot open shared object file: No such file or directory - /usr/local/rvm/gems/ruby-1.9.3-p194/gems/ruby-audio-1.6.1/lib/rubyaudio_ext.so (LoadError) from /usr/local/rvm/gems/ruby-1.9.3-p194/gems/ruby-audio-1.6.1/lib/ruby-audio.rb:6:inrescue in <top (required)>'

Any ideas what could be the cause for this?

Thanks.

Do you know where it is trying to find libsndfile.so.1? If I know that location, then I can try to add a symlink there and point it to where that file actually exists. These are the files I have on my machine (libsndfile.so.1 clearly exists):

/usr/local/lib/libsndfile.so
/usr/local/lib/libsndfile.a
/usr/local/lib/libsndfile.so.1
/usr/local/lib/libsndfile.la
/usr/local/lib/libsndfile.so.1.0.25
/usr/local/share/doc/libsndfile1-dev
/usr/local/share/doc/libsndfile1-dev/html/libsndfile.jpg
/usr/local/share/doc/libsndfile1-dev/html/libsndfile.css

If you are using a publicly available AMI, I can check and see if the libsndfile package is installed in a non-standard location. Otherwise, it looks for libsndfile-1.so or libsndfile.so in ['/opt/local/lib', '/usr/local/lib'].

I'm using Ubuntu 16. libsndfile is not install to that dir.
It is only installing as an .so.

I tried this, but no luck.

gem install ruby-audio -- --with-sndfile-lib=/usr/lib/x86_64-linux-gnu/libsndfile.so.1

find /usr -name 'libsndfile*'
/usr/share/doc/libsndfile1
/usr/lib/x86_64-linux-gnu/libsndfile.so.1
/usr/lib/x86_64-linux-gnu/libsndfile.so.1.0.25

This worked for me:

gem install ruby-audio -- --with-sndfile-dir=$(brew --prefix libsndfile)
