Hello dave, first of all thanks for your answer What i'm trying to do is to link an external button to the halt command, to power off the machine quickly, since the kernel has the acpi disconnected i can't use the normal power off button in the motherboard.
So i decided to create a component with a few lines in C to halt the machine when i require. The problem is that i can't get comp working with that function... i made and compiled with gcc a normal C executable file to halt the machine and worked ok, but when i use comp i can't compile the component, there is a problem with the stdlib.h library or something but i'm not sure. The main thing is that i'm trying to halt the machine with an external button and i'm trying to find the best solution. Thanks again for your concern. Best Regards.
