Subject: [openrisc] building the gcc
for c++ support with --enable-languages=c, c++
Hi all,Yes the tool chain for c++ is working .
one of the mistakes I made ( may be one can make) is to invoke the
wrong compiler tool for the c++ program. one should invoke or32-elf-
g++ instead of or32-elf-gcc ( initially I thought the gcc will take care
and do whatever required to be done for c++ , but no). another problem
i overcome was some how the the libraries were not linking . so I had to
use -L and -l options in the linker command or32-elf-ld .... to point to
the library directories and the libraries built for the target. I used gcclib
which is under one folder and libc which is under another folder . after
all this now the tool chain is working fine.
Thank you
Narender
