LinuxDC++ now requires OpenSSL in order to compile:
2006-12-04 - Steven Sheehy
* Upgraded the DC++ core to 0.698:
* The 0.691 core contains a security flaw so I recommend you upgrade ASAP.
* Support for non-TTH files was removed (by DC++, so don't complain to us).
* Added SSL support (thanks Mattias Webjörn Eriksson for some help with this).
* OpenSSL is now a required dependency to build.
* Added a "Security Certificates" page in the preferences dialog.
* Added a TLS port entry in the "Connection" page.
* Added "Ignore private messages from bots" option.
* Added "Ignore private messages from the hub" option.
* Added "Don't download files already in the queue" option.
* Removed "Ignore private messages from offline users" option.
* Removed "Only results with TTH root" option.
* Lots of other bug fixes to get the core to compile on *nix.
You may have to run scons --clean and/or delete the "build/" directory in order to get this update to compile.
