NetSSL requires OpenSSL release 0.9.8 or later. Unix ==== Most Unix systems already have OpenSSL preinstalled. If your system does not have OpenSSL, please get it from http://www.openssl.org/ or another source. You do not have to build OpenSSL yourself - a binary distribution is fine. If you do build OpenSSl yourself be sure to call ./configure --prefix=/usr --openssldir/usr/openssl make make install (with superuser rights) so that poco works out of the box Windows ======= The easiest way to install OpenSSL on Windows is to use a binary (prebuild) release, for example the one from Shining Light Productions that comes with a Windows installer. 1. Download OpenSSL (at least v0.98a) from: http://www.slproweb.com/products/Win32OpenSSL.html 2. Install OpenSSL (we assume you install to c:\OpenSSL) 3. Start Visual Studio, go to Tools->Options, under Projects->VC++ Directories add the following directories: - Include Files: C:\OpenSSL\include - Library Files: C:\OpenSSL\lib\VC 4. You are now ready to build NetSSL.
