Hi, your'e talking about the module cs_operonly_register.c and looking at the error code you are pasting, the error comes from a module called ircd_admin.c which stops all compilation for other module(s). So, if you want to compile cs_operonly_register.c module, firstly the ircd_admin.c needs to be fixed or have to be removed/deleted from the 'src/modules/' folder. I hope you got what i meant.
