Hi everyone,
I'm novice to bitcoin and I'm trying to compile it to study.
In Ubuntu 14 I have compiled all, and in the /usr/local/bin folder 7 files were created:
bench_bitcoin, bitcoin-cli, bitcoind, bitcoin-qt, bitcoin-tx, test_bitcoin, test_bitcoin-qt


When I click on any of them, Ubuntu displays an error: Could not display “bitcoind”. There is no application installed for “shared library” files. Do you want to search for an application to open this file?


Does anybody  know how to launch these files? Thanks!
