how to develop windows qt wallet on ubuntu ... how to setup environment .... any guide to help
Did you understand what you said?
Windows is one operating system
Ubuntu is different
For Ubuntu, you need to take the bitcoin qt wallet code and compile it.
Bitcoin Core wallet isn’t included in Ubuntu software repository, but we can easily install it from the Bitcoin Team PPA
1) Fire up a terminal window (CTRL+ALT+T) and run the following 3 commands to add the PPA, update local package index and install Bitcoin Core wallet.
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt update
sudo apt install bitcoin-qt bitcoind
2) bitcoin-qt provides a graphical interface, while bitcoind is the Bitcoin daemon. If you just want a graphical interface and have no plan to use the daemon, then don’t enter bitcoind in the command line.
Once installed, Bitcoin Core wallet can be started from Unity Dash or your preferred app launcher.
Or using the command below.
Upon first launch, it will ask you to set your bitcoin data directory which will be used to store the Bitcoin block chain and your wallet. The default is .bitcoin/ under your home directory. Make sure the data directory has more than 120GB free disk space.
