Can't download and compile Opa in Ubuntu 14.04 LTS

[riz007]

I followed the instructions to install Opa in my Ubuntu virtual machine, running on my Windows 64 bit platform, from https://github.com/MLstate/opalang/wiki/Building-Opa. I installed the files inside /bin directory but got the following error messages:

riz@ubuntu:/bin$ cd opalang
riz@ubuntu:/bin/opalang$ sudo ./configure

How can I get rid of this issue? Any help would be appreciated. Thanks.

You should not use sudo for configure.

Also, for the next step you're missing dependencies (java is needed for closure which we use to minimize generated JS).
