I need to install Protocol Buffer 2.4, but I happened to have installed 2.6 already. How can I downgrade?
Thank you in advance!
One of the ways, in the folder of Protocol Buffer 2.6
type the command:
sudo make uninstall
After, follow this tutorial to install version 2.4. I hope it could be helpful!
You should probably
make uninstall
the previous version (while inside the source folder). And then
make install
the new version.
