From AMule Project FAQ
How to get crypto++ working on sarge debian (from Debian sources):
Get libcrypto++ sources from sid
Add this line to /etc/apt/sources.list:
deb-src http://ftp.yourcountrytld.debian.org/debian/ sid main non-free contrib
and run
apt-get update
apt-get source -b libcrypto++
or
apt-get source libcrypto++, cd libcrypto++-5.1, dpkg-buildpackage -b -B -uc
After installing (dpkg -i libcrypto++5.1.deb), make a symbolic link in /usr/include/crypto++ from cryptopp_config.h to config.h in the same directory:
ln -s /usr/include/crypto++/cryptopp_config.h /usr/include/crypto++/config.h
NOTE: you have to link the files because of a bug in Debian libcrypto++ package
Self-compiling Crypto++
You could compile libcrypto yourself too. Take a look at our compilation howto.
