I found that there are some people on GitHub that collect source codes from early UNIX ages, like first compilers, first shells, or PDP7-UNIX. Just to made them available in one place (slightly decentralize access to them) – I decided to create gitlab.com account `UNIX-history` for them.

You can find there source codes from 1970, nicely commented and manually formatted, before this all happened.

You can work with SQL queries in Qt and SQL in many different ways, here I will show you how I came up with a working method. To keep things simple, I am not going to use any UI to print or edit queries. It will be just source code and stdout, as a database engine I will use SQLite3.

After you created your project, edit project.pro and locate line:

QT       += core

Modify this line by adding `sql`:

QT       += core sql

Since now, when you compile your project, QtSql module will be linked to the project:

g++ -Wl,-O1 -Wl,-O1,--sort-common,--as-needed,-z,relro -o QtSql main.o   -lQt5Sql -lQt5Core -lpthread

Just a simple tutorial to show you how to add static code analysis plugin in QtCreator on Liunx.

cp lib/qtcreator/plugins/libQtcCppcheck.so /usr/lib/qtcreator/plugins/
