body: <p>I am using Windows 10. When I tried to build <a href="http://hyperledger-fabric.readthedocs.io/en/latest/chaincode.html" rel="noreferrer">Chaincode</a> it reported this error</p>
  
  <pre><code># github.com/hyperledger/fabric/vendor/github.com/miekg/pkcs11 
  exec: "gcc": executable file not found in %PATH%
  </code></pre>
  
  <p>My chaincode imports:</p>
  
  <pre><code>import (
      "fmt"
      "strconv"
  
      "github.com/hyperledger/fabric/core/chaincode/shim"
      pb "github.com/hyperledger/fabric/protos/peer"
  )
  </code></pre>
