How can i install/integrate ovirt-engine-sdk in my rails application? Thanks in advance for any help. Please let me know if there are any other files or information you need to assist.

Answer 1

I had a very similar problem to this. I ran

gem install ovirt-engine-sdk -- --with-cflags="-Wno-error=implicit-function-declaration”

followed by

bundle install

and everything worked.
