[Vm-dev] Extended Clipboard

[Hilaire Fernandes]

Hi Dave,

I put my hand on the VM, just enough to be able to compile it and run a 
GDB session with a breakpoint in the plugin. I followed the instructions 
on VM github repo VM to compile a COG version wtih debug symbols for 
Linux. I did not met the problem with flag you mentioned, I am still on 
Ubuntu 20.04, may my gcc version is older.

The Squeak wiki page about VM source seems wrong, it writes github repo 
is for archiving and development goes on squeakvm. From my perception it 
is the contrary.

I will try to put together the peaces from the latest Etoys OLPC VM Juan 
pointed.

Thanks

Hilaire
