Qca Dependencies

Required

make-ca-1.16.1, CMake-4.4.2, Qt-6.11.2, and Which-2.25

Optional

Cyrus SASL-2.1.28, GnuPG-2.5.21, libgcrypt-1.12.2, libgpg-error-1.61, nss-3.126, NSPR-4.40, p11-kit-0.26.5, Doxygen-1.18.0, and Botan

Installation of Qca

First, modify the package to be compatible with OpenSSL4: 

patch -Np1 -i ../qca-2.3.10-openssl4_fixes-1.patch

Now, fix the location of the CA certificates: 

sed -i 's@cert.pem@certs/ca-bundle.crt@' CMakeLists.txt

Install Qca by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=$QT6DIR            \
      -D CMAKE_BUILD_TYPE=Release                \
      -D QT6=ON                                  \
      -D QCA_INSTALL_IN_QT_PREFIX=ON             \
      -D QCA_MAN_INSTALL_DIR:PATH=/usr/share/man \
      .. &&
make

To test the results, issue: make test.

Now, as the root user: 

make install

Command Explanations

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

-D QT6=ON: This switch ensures that the package is built with Qt-6.11.2.

-D QCA_MAN_INSTALL_DIR:PATH=/usr/share/man: This switch installs the qca man page in the normal location.
