Hello,

I would like to use virtual methods in my C++-project.
Then I link the project with the following linker script, the shows alot
of errors:

Linking arm_gcctest.elf ...

It seems that there are some entries missing in the linker-script for
"virtual functions" (...linkonce...). Take a look into the linker-script
from the lpc2129-newlib_cpp-example in the WinARM examples-collection.
If the information given there does not help: create a minimal
example-project with all needed files (source-code, linker-script,
makefile) where you see the error-messages, place it somewhere on an
internet-server and give the URL. I will take a look into this if I have
some time or others may jump in and try to help you.
