Thanks for the inputs , will try them. Initially when I tried building I
got "ld terminated with signal 9 error ", after which I increased the swap
file sizeThen, it got successfully built once.
 Next I tried building this plugin as given in
https://kevinaboos.wordpress.com/2013/07/29/clang-tutorial-part-iii-plugin-example/
.
Even building a plugin requires building clang executable again? In this
case , I received this error, "error: ld terminated with signal 7 [Bus
error], core dumped ". Why did this happen?

Basically I want to change the checker GenericTaintChecker.cpp into a
plugin . Where can i find the required instructions?

Regards,
Ashwin
