If the question is whether GPL allows GPL'ed code to use functionality<br>

does and (b) GPL does not fetter a user's freedom to use the GPL'ed<br>

However, copies can only be redistributed if the licences for all the GPLed components grant specific permission to link against that proprietary library.<br>

Giving someone software under a purported GPL licence without giving them dispensations to link with the proprietary libraries makes the GPL pretty pointless. It would be better to use a licence that reflects the intended redistribution terms.<br>

I believe you can actually modify and link GPLed code with proprietary code when you are not the owner and don't have a dispensation, but you are then not allowed to give it to anyone else.<div class="im"><br>

Please note that FSF's answer to "Can I write free sfotware that uses<br>

"please do not do it - write a GPL compatible, free software library".<br>

"It" here, is issuing a dispensation.<br>
<br>
However, note that the intention of the GPL is that most GPLed programs should not be the sole intellectual property of the current author. By linking with proprietary libraries, you forego the right to distribute versions that are derivatives of other GPLed code.<br>
<br>
Note the disputed legal issue is about when a binary program is a derivative work of a software library.<div><div></div><div class="h5"><br>
