Re: [avr-gcc-list] GCC plugin for avr-gcc

[Sandeep K Chaudhary]

Hi Senthil,

As pointed out by Jeremy, there is some issue with my plugin_init function. The plugin infrastructure seems to be in place. 

I will try to figure out the issue, and resolve it.

Thanks a lot for all the help !

Sandeep.

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

address@hidden:~/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

address@hidden:~/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.

Hmm - this is what I get on the latest released toolchain build for
Linux x86_64.

$  ~/downloads/avr8-gnu-toolchain-linux_x86_64/bin/avr-gcc -v
Configured with:
/data2/home/toolsbuild/jenkins-knuth/workspace/avr8-gnu-toolchain/src/gcc/configure

and disabled-shared is present. Can you dump the full command output?
