However, it is possible to link against the library at + compile-time by configuring Qt with the \c{-openssl-linked} option. + + When building a version of Qt linked against OpenSSL, the build system will + attempt to link with libssl and libcrypt libraries located in the default + location on the developer's system. This location is configurable: + set the \c OPENSSL_LIBS environment variable to contain the linker options + required to link Qt against the installed library. For example, on a Unix/Linux + system: + + \code + ./configure -openssl-linked OPENSSL_LIBS='-L/opt/ssl/lib -lssl -lcrypto' + \endcode + + To disable SSL support in a Qt build, configure Qt with the \c{-no-openssl} + option. + + \section1 Licensing Information + + \note Due to import and export restrictions in some parts of the world, we + are unable to supply the OpenSSL Toolkit with Qt packages. Developers wishing + to use SSL communication in their deployed applications should either ensure + that their users have the appropriate libraries installed, or they should + consult a suitably qualified legal professional to ensure that applications + using code from the OpenSSL project are correctly certified for import + and export in relevant regions of the world. + + When the QtNetwork module is built with SSL support, the library is linked + against OpenSSL in a way that requires OpenSSL license compliance. +*/ |
