include steam problem

I’m trying to include steam in the project, I add the line in the .ini file and see the login window in the standalone
When I try to include the header like isteamfriends.h isteamutils.h or steam_api.h I receive sintax missing error in myproject file (";" missing)

line 305 column 1:

if (FParse::Token(Cmd, Parm, ARRAY_COUNT(Parm), 0) && Parm[0] != '-')

error C2059 sintax error missing “;” (ARRAY_COUNT(Parm) comma is red marked)
line 306 column 1:


error C2143 sintax error missing “;” before “}”

I don’t know what I’m missing/doing wrong. Someone knows how to resolve?
