step1 : clone "GCC compiler" setting and named it "GCC Compiler BBB";
step2 : create a project, named "test", and set it's compiler to "GCC Compiler BBB";
step3 : save the project and close the cb
step4 : restart cb, and delete the "GCC Compiler BBB";
step5 : open the "test" project, now......
A project that uses an unknown compiler for the IDE cannot be setup. Thus all options are greyed. That's 100% correct behaviour.
But I do the step 6:
Step6 : Reset the Compiler to GCC. (and save the project after reset)
Result : the options of compiler also disabled.
-----
edit : AND , only the options of "root" is disabled, the "DEBUG" or "RELEASE" 's options can be edit.
