I tried both opensll 0.9.8g and 0.9.7f on QNX4.25 with watcom 10.6 compiler, and I got error message "ssl handshake failure" on server side when client tries to connect it. However, the same sample codes/openssl are working in QNX6.3. Any thing I missing?
Thanks for help.
Here are my sample codes.

QNX 4.25 and QNX6.3 use different compilers.
For example Watcom has a default packed structure, which may could be the problem.
You can try this by filling up the structures, so arrays and blocks start on byte boundaries. |
