Viola Install — Teach My Ass Promise Aka

Run:

./configure --prefix=/usr/local

Expected error:
ERROR: libvoip not found

The “teach my ass” fix:
Viola needs an ancient version of libvoip (1.2.4). You must compile it manually:

git clone https://github.com/voip-tools/libvoip-legacy.git
cd libvoip-legacy
./autogen.sh
./configure
make
sudo make install
cd ..

Now re-run Viola’s ./configure.

git clone https://github.com/your/viola-repo.git   # replace with actual viola URL if public
cd viola
make
sudo make install

If Viola isn’t in standard repos, the author may provide a binary. Check viola --help after install.

Check your version:

lsb_release -a

Now that you’ve kept the promise to yourself: teach my ass promise aka viola install

If “Promise AKA Viola” means the actual viola package (minimal BDD test runner):

npm install -g viola
viola test/*.js

Test file example:

// test/sample.js
const assert = require('assert');
describe('Promise', () => 
it('should resolve', () => 
return Promise.resolve(42).then(val => 
assert.equal(val, 42);
);
);
);
 Expected error: ERROR: libvoip not found The “teach
