Usually I understand what the compiler is complaining about and find what I have boogered up, but this one has me mystified.

It's pointing to the line:

int LCDStringPx( const __memx uint8_t font[], const __memx char* s)

and it just says, "in convert_debug_memory_address, at cfgexpand.c:2528"

Here's the whole function

int LCDStringPx( const __memx uint8_t font[], const __memx char* s)
{
	int l = 0 ;
	while (*s != 0) 
	{
		char c = *s++ ;
		uint16_t BitPointer = * (font + (c-31)*2);
		BitPointer = BitPointer | ((uint16_t) * (font + (c-31)*2 + 1)<<8) ;
		uint8_t CharWidth = * (font+BitPointer++) ;
		l += CharWidth + 1 ;
	}	
	return l ;
}

"Haylp! Ah says Haylp!"

so there still seem to be problems with using memx.
Torby, what studio version do you use?

This seems to highlight a fault in AS6's "Error List" too. In GJL's bug report the full message is

"internal compiler error: in something at somewhere.c:N"

but AS6 is just showing:

"in something at somewhere.c:N"

What happened to the "internal compiler error" part of the message??

Cliff,
to me that first line:
"internal compiler error: in something at somewhere.c:N"

would make as much sence as:
"in something at somewhere.c:N"

to more experienced users would this make sense at all?
I would expect a bit more detail to give some more error details.

Actually, the "internal compiler error" is MORE important initially. It says that this is not primarily an error in your code, but that the compiler has encountered a bug in the compiler itself. Lie hitting an ASSERT() or something like that.

Anyway, the first thing when encountering an error message you don't understand is to enter it verbatim into Google (removing anything that you identify to be specific for your code, like filename, line number, identifier name...).

And Torby: It's much easier for someone else to read, copy and search for an error message if you switch over to the Output tab and copy the text from there (rather than posting a screen dump). This would also have given us the complete error message. IDEs and filtered error lists are all fine most of the time, but in these cases you really want the actual output from the compiler.

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here. 

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

Oh. I never think of the output tab.

Ok. I'll make another case :roll:

 error: in convert_debug_memory_address, at cfgexpand.c:2528

Actually that is a bit of a hopeless message! The term "internal compiler error" is far more revealing than just "error:".

I'm guessing it means there's something wrong at line 2528 in cfgexpand.c, which isn't my program.

I think there's a newer version of studio available, but I can't download anything till Saturday.

As a work around, compiling without debug info might work. (Who needs debug info anyway?)

avrfreaks does not support Opera. Profile inactive.

Well, I'll be! It does build with release turned on. 'Course, my handy AtmelICE won't help me figure out where my logic is screwy. Or maybe it's just 'cause I've been doing something different for a few days.

So, what kind of lice are "Atme lice?"

Eee... And my logic seems very messed up.

Oh, and I found one of those atmelice. I had to google.
