using C++

[btyla]

Hi,

Does the current tool chain support C++ development? I tried to some tutorial code and added a dummy C++ class, it all compiled without warning but LD was complaining about some undefined references about (my guess) low level vtable code (__register... __deregister...something).

Must I manual include some library code?

TIA

How did you compiled it ? Can you copy/paste explicit compilation and error messages ?

However, I just suppose you linked using "gcc" or "ld" directly, and not using "g++", which automagically links the "libstdc++.a" library in.

From my experience, you need to add -fno-exceptions to the g++ command line -- exceptions don't seem to work, w/ my version of the toolchain at least. Exceptions are nasty, performance-robbing things (in c++ anyhow), and should be avoided.

Add -fno-exceptions as mharris suggested, remove -nostdlib, or use ee-g++ instead of ee-gcc as pixel suggested. Take your pick. In the future you should read up on the compiler and linker options so that you know which option does what. Manuals are on the web or installed locally with the toolchain.
