POexecSync with meteor
text
Body
copied!<p>I am trying to use the <code>execSync</code> package to get synchronous shell functionality. Although I initially had problems due to the lack of the <code>binding.node</code> file, I solved it by running <code>node-gyp</code> in proper <code>execSync</code> directories. Now, I can call <code>execSync</code> functions within node without any problems. </p> <p>However, when I try to use the functions from within meteor, I get the following error:</p> <pre><code>Running on: http://localhost:3000/ /usr/lib/meteor/bin/node: symbol lookup error: /home/onur/node_modules/execSync/node_modules/ffi/node_modules/ref/build/Release/binding.node: undefined symbol: _ZNK2v85Value6IsNullEv Exited with code: 127 Your application is crashing. Waiting for file change. </code></pre> <p><strong>Note:</strong></p> <p>A quick inspection over the net showed that the symbol belongs to the V8 library.</p> <p><strong>The Code</strong></p> <p>I define the following in <code>Meteor.methods</code>.</p> <pre><code>getpuzzle: function (clu, lo, hi) { var require = _meteor_bootstrap__.require; var exec = require('execSync'); var sudoku_str = exec.stdout(path_sudoku_gen+" "+clu+" "+lo+" "+hi); console.log(sudoku_str); return sudoku_str; } </code></pre> <p>I am trying to figure out the interaction between the server and client. Basically, I'm trying to do <a href="http://www.scriptol.com/javascript/nodejs-php.php" rel="nofollow">this</a>. The function on the client side requires a string that is returned by a python script executed on the server side. I tried a dirty hack using a global variable, but it still did not matter because the script is run asynchronously. Can I do this without synchronous execution? I cannot fully grasp the model for client-server interaction, so if there is a right way to do it, feel free to correct me. </p>
