Introduction to Qca

Installation of Qca

Install Qca by running the following commands: 

sed -i '217s@set@this->set@' src/botantools/botan/botan/secmem.h &&

./configure --prefix=/usr            \
                 --no-separate-debug-info \
            --certstore-path=/etc/ssl/ca-bundle.crt &&
make

To test the results, issue make test.

Now, as the root user: 

make install

Command Explanations

sed -i '217s@set@...: This sed fixes compiling with GCC 4.7 and newer. It is safe to omit when compiling with older GCC versions.

--certstore-path=/etc/ssl/ca-bundle.crt: Causes the build to use the system-installed CA Certificates instead of a bundled copy.

--no-separate-debug-info: Prevents installation of a separate library and program file with debug information.
