This is how I build it:
openssl:
/config --prefix=... --openssldir=...
make
make test
make install
mod_ssl:
/configure --with-apache=...
apache:
/configure
php:
CFLAGS='-I /usr/local/include/openssl' ./configure --with-apache=...
(other options)
make
make install
apache:
SSL_BASE=/usr/local
/configure --prefix=/www --activate-module=...(PHP) --enable-module=ssl
make
make certificate
make install
Isn't this the correct way to build it if I don't want any DSO's at all? Or
have I built it incorrectly?
Thanks for the help so far; hope this can be resolved
