I use perl 5.8 and compile and run my server just fine using this version. Directions:
- Download your perl 5.8 and install it.
- Navigate to your CORE folder of perl (default: c:\perl\lib\CORE).
- Find perl58.lib.
- Make a copy of this file (so you now have perl58.lib and copy of perl58.lib).
- Rename the copy perl510.lib.
- Compile.
- Run eqemu with your new compile.
This should work for you. I don't see anything specific that would make this not work. Post if you have a problem.
