[gem5-users] Adding new replacement policy error

[John H via gem5-users]

Hello,

I tried creating a separate .cc and .hh file for implementing a new
replacement policy and added it to Scons within replacement policies.
However, when i run gem5 build, I get the following error message
build/X86/mem/cache/replacement_policies/ship_rp.cc:13:22: error: 'Params'
does not name a type
 SHIPRP::SHIPRP(const Params *p)
                      ^

 ^
scons: *** [build/X86/mem/cache/replacement_policies/ship_rp.o] Error 1
scons: building terminated because of errors.

Can you please guide me on how to fix this?

Thanks,

John
