[MiNT] C++ Stuff

[Mark Duckworth <mduckworth@atari-source.org>]

Hey guys,

I am converting GIM and probably SUM to C++.  There's a number of 
obvious advantages to using it for a high level app and I've always 
wanted to learn it because it offers the majority of the features I am 
very used to being a day by day C# .net programmer in a language that 
will run on anything, even MiNT ;) 

Everything is fine except when I use vectors so far.  It seems if I use 
vector<T>.push_back() there is a call to an FPU function.  In gdb this 
results in an EMTTRAP emulation trap and the program stops running.  So 
am I correct in saying that if I want my program to run on 68000 I would 
need to compile with libm in order to provide libstdc++ with the math 
support it desires?  It works when I compile with -m68020-60.

Does anyone else think it's strange that something as simple as 
vector<T> would need FPU functions?

PS: Adapting a windom program to run in c++ is kind of a pain ;)  But I 
was shocked to find that after doing all of the source modifications, 
converting to proper objects for buddies and conversations, and then 
teasing out some other final problems (addition of extern "C" to some 
spots and the replacement of many malloc's with new char[]'s) that GIM 
actually worked and signed in!  There are some things to do to fix 
pointers and stuff like that but it's pretty downhill from here ;)  Now 
that it's C++ it'll be easier to expand and it won't be using my 
horrible home brew linked list and string handling code ;)

I thought at one point zorro was using G++ for zview but now when I look 
it is all C.

Thanks,
Mark
