Re: [Gems-users] GCC compatibility

[Mahmood Naderan <mahmood.nt@xxxxxxxxx>]

While making the Opal, I get these errors:
system/pseq.h: In member function ‘cache_t* pseq_t::getDataCache()’:
system/pseq.h:417: error: cannot  convert
‘generic_cache_template<generic_cache_block_t>*’ to ‘cache_t*’ in
return
system/pseq.h: In member function ‘cache_t* pseq_t::getInstructionCache()’:
system/pseq.h:421: error: cannot convert
‘generic_cache_template<generic_cache_block_t>*’ to ‘cache_t*’ in
return

The staements are:
  cache_t *getDataCache( void ) {
    return (l1_data_cache);     // error line 417
  }
  /** get the l1 instruction cache interface */
  cache_t *getInstructionCache( void ) {
    return (l1_inst_cache);     // error line 421

How did you correct them in 4.4.1? Please let me know.
