VLC: error: read-only variable is not assignable

[amadeus24]

It was great to port VLC to the last version and it runs really stable. Yesterday I tried to update my tree, but updating from 2.0.1 to VLC-2.0.1_1, the build failed. I cleaned then all installed ports and start the installation again, but was also not successful.

Last lines of main.log:

The actual relevant error in the log appears to be:

Since this error I realized there was an update to the port, but I still have the same problem. Do you know any workaround?

[nonstop.server@…]

Replying to ag@…:

Do you know any workaround?

Take a look at #34741, it seems to me this is a likewise problem.
In my case it was an error due to the fact that my XCode was out of date.
On advice of Jeremy I upgraded my XCode to the latest available version for OSX 10.6 and was able to install VLC.
Note: Upgrading the current port of VLC did not work for me, I had to disable the installed version and perform an install of the latest one.
I hope this will help you to get it working.

Thanks! With the update of XCode everything get fine. In my opinion the ticket can be closed.
