Luma curve display thingy in ML (looking for the)

[ItsMeLenny]

I remember using this luma curve kind of thing in ML where it would print out the curve of the light over exposure stops.
It would stop itself down using the shutter speed and print out a green curve on a graph to show how many stops the camera gets.
I think when I used it it was in the don't click me button at the time. It was back when ML iso was introduced, however I still see the graphs used by some of the devs.

Old code, which I don't know if it still works: https://bitbucket.org/hudson/magic-lantern/src/tip/modules/iso_test/
New one: https://bitbucket.org/hudson/magic-lantern/src/iso-research/modules/raw_diag/

[ItsMeLenny]

Ah sweet, thanks.
Is there a compiled version of this?

Is the latter only for raw, or can it be used for jpeg/mp4?

http://www.magiclantern.fm/forum/index.php?topic=10111.0

There is some JPG based stuff iirc.

[ItsMeLenny]

oh yeah, the .mo is on that page, thanks.

I also just grabbed ML source and will compile if it doesn't work.

[ItsMeLenny]

Although compiling ML doesn't seem to be as simple as I once did it before.

Is there a list of libs needed on linux, I had a look through some tutorials in here but none of them seem to mention.

[Audionut]

What error messages?

Have you seen this.

[ItsMeLenny]

it wasn't looking in the right directory for my gcc arm, or for the right version for that matter
but from what you linked, and from the failed build just now, it looks like i have to grab a specific version
actually, no it doesn't they just grab a launchpad version, maybe i am having issues

gcc version 4.8.3 (Ubuntu 4.8.3-12ubuntu3)

long post just if you're curious, scroll to bottom for errors

[ItsMeLenny]

eh, never mind, I managed to compile it for 550D, and compile the default modules, but I can't seem to compile modules that arn't the defaults.

[Audionut]

Did you add them to the makefile in the module directory?

[ItsMeLenny]

I ran:
/magic-lantern/modules$ make all GCC_VERSION=-4.8 ARM_PATH=/usr ML_MODULES_DYNAMIC?=iso_test

which was said to may not work (also had to change a letter in a piece of code as the name was too long)
but when I try raw_diag for example... oh wait, no I wasn't trying raw_diag I was trying adtg_log for some reason...
but it doesn't work either
ok but I tried lua and it compiled fiine, so it must just be some broken modules, never mind me



on a side note:
could something like that raw_diag or iso_test be scripted in lua, or does lua only work for automating camera funtions?
