Hi guys, I am trying to run a gcc plugin that I created. I have followed the steps mentioned in the followiing tutorial to create the plugin http://lwn.net/Articles/457543/ I am able to successfully build the plugin shared object. However, I can not run the plugin. It gives errors related to undefined symbols. Below is the terminal snippet. sandeep@ubuntu:~/myplugin$ /usr/bin/gcc -fplugin=/home/sandeep/myplugin/speller.so -c test.c cc1: error: cannot load plugin /home/sandeep/myplugin/speller.so /home/sandeep/myplugin/speller.so: undefined symbol: warning_at I can see that the mentioned symbol is indeed undefined using following sandeep@ubuntu:~/myplugin$ nm -D -C speller.so | grep warning_at U warning_at And I see that sandeep@ubuntu:/usr/lib/gcc/x86_64-linux-gnu/4.7.2$ pwd /usr/lib/gcc/x86_64-linux-gnu/4.7.2 sandeep@ubuntu:/usr/lib/gcc/x86_64-linux-gnu/4.7.2$ nm -D -C $(gcc -print-file-name=cc1) | grep "warning_" 0000000000c1e5a0 T warning_at(unsigned int, int, char const*, ...) What am I missing? How should I link the libraries correctly? Please help. Thanks, Sandeep.
