OpenSSL

OpenSSL comes with RHEL4. On Solaris it seems exist in /usr/lib/mps and /usr/include/mps but *.so libraries only, no *.a. Anyway, to install it on Solaris do following:

Download openssl-0.9.8d.tar.gz from web to /usr/local/downloads. Then:

 cp openssl-0.9.8d.tar.gz /usr/local/src/
 cd /usr/local/src/
 gunzip openssl-0.9.8d.tar.gz
 tar xvf openssl-0.9.8d.tar
 cd openssl-0.9.8d

Configure for Sparc Solaris (32-bit version):

 ./Configure --prefix=/usr/local

Configure for Sparc Solaris (64-bit version):

 ./Configure --prefix=/usr/local

Configure for Opteron Solaris (32-bit version):

 ./Configure --prefix=/usr/local solaris-x86-cc
       other possible flags:
 ./Configure --prefix=/usr/local solaris-x86-gcc
 ./Configure --prefix=/usr/local solaris64-x86_64-cc

Compile and install:

 gmake
 gmake install
