Hi

"-Og" is not a valid optimization level for the GCC version you are using. Try -O2 or -O0.

hello

thanks for the response.

how can i resolve this problem?

thanks.

Change it where your compiler options are in your project, I cannot know. It could be a Makefile or Eclipse project properties, it depends on how your project is setup.

i tried to make some chages in the makefile but the settings stills the same after
rebuilding the project.

thanks.
