Qca-2.3.1

Introduction to Qca

Qca aims to provide a straightforward and cross-platform crypto API, using Qt datatypes and conventions. Qca separates the API from the implementation, using plugins known as Providers.

This package is known to build and work properly using an LFS-10.0 platform.

Installation of Qca

Fix the location of the CA certificates: 

sed -i '[email protected]@certs/ca-bundle.crt@' CMakeLists.txt

Install Qca by running the following commands: 

mkdir build &&
cd    build &&

cmake -DCMAKE_INSTALL_PREFIX=$QT5DIR            \
      -DCMAKE_BUILD_TYPE=Release                \
      -DQCA_MAN_INSTALL_DIR:PATH=/usr/share/man \
      .. &&
make

To test the results, issue make test.

Now, as the root user: 

make install

Command Explanations

-DCMAKE_BUILD_TYPE=Release: This switch is used to apply a higher level of compiler optimizations.

-DQCA_MAN_INSTALL_DIR:PATH=/usr/share/man: Install the qca man page in the normal location.
