Compilation errors with C++ libraries (game-porting)
To all, have just decided to dust off my dreamcast after finding a Train controller, keyboard, mouse and VMU-Microphone in Japan to use with it.
I thought it'd be a fun challenge to port a game over to the DC though am having some issues compiling.. have been slowing hacking through the code to make it fit the DC but it seems that I've found the file-handling procedures which want STL Libraries? GCC then doesn't know what to do with itself:
Code:
fileio.o(.gnu.linkonce.t._ZNSt8_Rb_treeISsSt4pairIKSs16TarFileListEntryESt10_Select1stIS3_ESt4lessISsESaIS3_EE8_M_eraseEPSt13_Rb_tree_nodeIS3_E+0x84):

^^ my cool error... G++ is having a tiff with it's own headers and since it's in the linking stage it's obvious I have left out a library but as to which one I don't know...
I suppose I just need to know what 'standard C' libraries I can use with KOS/sh-elf and what I can't...
Another chunk of error text from the same linking session:
Code:

/usr/local/dc/openttd/src/fileio.cpp:98: undefined reference to `std::_Rb_tree_decrement(std::_Rb_tree_node_base*)'
Any insight would be greatly appreciated!
