Qrencode Dependencies
Recommended
Optional
Doxygen-1.9.8 for generating documentation, and SDL2-2.28.5 for tests
Installation of qrencode
Install libqrencode by running the following commands:
./configure --prefix=/usr && make
If you have installed Doxygen-1.9.8, 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 SDL2-2.28.5.
--without-tools: This option prevents building the
qrencode executable, removing the need for
libpng-1.6.40.
