SX200IS Compilation problem.

There are five 'sub_' entries missing from the auto-generated 'stubs_auto.s'  file so the compiler gives error messages.


What can be causing this  ?

In trunk chdk? Rev 825 builds sx200is 100c fine for me.

But you should be able to fix it by placing sx200is fw dump as platform/sx200is/sub/100c/PRIMARY.BIN and running make to regenerate that file. Incorrect timestamps or something like that could be confusing make, that could probably be fixed by deleting the old file. If still in doubt, revert to a clean trunk.

I copied all of rev 824 sx200is folder to my own build (and sx200is loader).

I run gmake PLATFORM=sx200is PLATFORMSUB=100c fir and PRIMARY.BIN is still 4,096KB.
I get the same five entries missing.

Can you list the missing entries ?

Did check whether they exist in the version in SVN ? I would guess they must, since the autobuild works, which means something is going wrong in the code that generates it on your end.

Sure ...

they are all in boot.c and are all nullsubs (trunk 824)

I have replaced the Tools folder with the latest trunk version but that makes no difference.

I do not use the CHDK Makefile or Makefile.inc.


Difficult to see how that affects it.

A bunch of the sed stuff that generates stubs_auto.S is in the makefile in CHDK.

No, I meant whether they are in the stubs_auto.S in CHDK SVN

edit:
which they are of course. If they are all nullsubs, you can just comment them out and save a bit of space ;)

Well, it is a bit worrying not knowing why it happens, the Make files are complicated enough as it is.

Are you referring to the 'sed' in  makefile_sub.inc ?

CHDK has :-         sed 's/.*B[[:alpha:]]*[[:space:]][[:space:]]*sub_\\([0-9A-Fa-f]*\\).*/\\1/' | \

I have:        sed 's/.*sub_\\([0-9A-Fa-f]*\\).*/\\1/' | \

replacing my version with the CHDK version makes no difference.

this will get caught by the commented. // nullsub_...

I suspect your stubs_auto.S didn't get rebuilt after you made the change. The CHDK one was changed for this very reason.

Well done !

You posted seconds before I was about to.

Removing those comments solved the problem.

I have looked at a 'sed' reference but can you explain exactly what my version does ?

.* matches anything preceding sub_. Since sed is greedy, that gobbles up the "B sub_FF123456" all the way through the comment and null. The \([0-9A-Fa-f]*\) matches 0 or more times, so it captures an empty string, which via the \1 replaces the output.

The CHDK version should really use at least a \+ for the capture, but it at least explicitly looks for the B
