Hello world

I’m trying to debug an application running into a ptty terminal set in raw
mode.
When I set a breakpoint in my software at the following line :

printf( “car read : %X - i:%8ld\n”, car, i );

the debugger doesn’t stop when I hit a key

I compile my application with the command :

qcc -g test.c -o test_g

I join my source code (test.c)


Someone could tell me why the debbugger doesn’t stop.

Thanks!

Does this line get executed? i.e. does your application
read a key, and print out the character read?

Yes.

We have the same problem with DDD. see the question titled “How to debug
this program with DDD?” in this forum

thanks,
