User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/qrencode

Installation of qrencode

Install libqrencode by running the following commands:

./configure --prefix=/usr &&
make

If you have installed Doxygen-1.9.1, you can build the documentation by issuing:

doxygen

The tests must be run after installing the package.

Now, as the root user:

make install

If you have built the optional documentation, install it as the root user:

install -vdm 755 /usr/share/doc/qrencode-4.1.1 &&
mv html/* /usr/share/doc/qrencode-4.1.1

To test the results, if you have passed the --with-tests option to configure, issue: make check.

Command Explanations

--with-tests: This option allows building the test programs. It requires SDL2-2.0.14.

--without-tools: This option prevents building the qrencode executable, removing the need for libpng-1.6.37.
