Estimated disk space required: 5.0 MB (with documentation, add 5 MB for tests)
Estimated build time: less than 0.1 SBU, add 0.1 SBU for tests
Doxygen-1.12.0 for generating documentation, and SDL2-2.30.8 for tests
Install libqrencode by running the following commands:
./configure --prefix=/usr && make
If you have installed Doxygen-1.12.0, 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.
--with-tests: This option allows
building the test programs. It requires SDL2-2.30.8.
--without-tools: This option prevents
building the qrencode
executable, removing the need for libpng-1.6.44.
