App starting twice?

1

Hi,
I made a simple CLI app which reads the arguments that are given to it. It’s crashing as soon as I try to use the output of le_args_getArgs(), but it’s still working.
So I wondered what was going on and then I saw that the app is somehow started twice. One instance gives the correct behavior, but the otherone is crashing because of a NULL pointer:

INFO | testcli[32064]/testCliComp T=main | testcli.cpp _testCliComp_COMPONENT_INIT() 17 | num args: 0
INFO | testcli@0[32065]/testCliComp T=main | testcli.cpp _testCliComp_COMPONENT_INIT() 17 | num args: 2
INFO | testcli[32064] | num args: 0
INFO | testcli[32064] | args: (null)

My test.sdef:

commands:
{
	testcli = testcli:/bin/testcli
}

My testcli.adef

start: manual

executables:
{
	testcli = ( testCliComp )
}

processes:
{
	run:
	{
		( testcli )
	}
}

Why is the app starting twice? What’s going on here?

Thanks,
Simon

You can use “app runproc” and see if it will start correctly

E.g.
app runProc modemDemo send --exe=send – 1234567 “Online”

I tried your suggestion, but it’s behaving exactly the same as before.

I don’t see problem, you can try with my modemdemo1 application.

I can see that it’s starting twice with 2 different PIDs.
Anyways, I went another path where I parse the arguments not in the COMPONENT_INIT, and that works.

I’m just curios why the app is started twice.

no idea, but it is good that now it works.
