Re: GCC plugin for avr-gcc

And also, when I try "fplugin" with avr-gcc or avr-g++, I get the following
-

sandeep@ubuntu:~/ispec/tool/gcc_plugin/gimple$ avr-gcc
-fplugin=/home/sandeep/ispec/tool/gcc_plugin/gimple/plugin.so -mmcu=atmega8
-c ledchase.c
cc1: error: fail to initialize plugin
/home/sandeep/ispec/tool/gcc_plugin/gimple/plugin.so
sandeep@ubuntu:~/ispec/tool/gcc_plugin/gimple$ avr-g++
-fplugin=/home/sandeep/ispec/tool/gcc_plugin/gimple/plugin.so -mmcu=atmega8
-c ledchase.c
cc1plus: error: fail to initialize plugin
/home/sandeep/ispec/tool/gcc_plugin/gimple/plugin.so

Does this mean that that the "fplugin" option is present with both avr-gcc
and avr-g++ but there is some other problem?

Please let me know.

Thanks a lot,
Sandeep.
