Estimated build time: less than 0.1 SBU, add 0.1 SBU for tests
Doxygen-1.13.2 for generating documentation, and SDL2-2.30.11 for tests
Install libqrencode by running the following commands:
sh autogen.sh && ./configure --prefix=/usr && make
If you have installed Doxygen-1.13.2, 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/libqrencode-4.1.1 && mv html/* /usr/share/doc/libqrencode-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 SDL2-2.30.11.
--without-tools: This option prevents
building the qrencode
executable, removing the need for libpng-1.6.47.
