Re: [darktable-dev] Wrong lens detected

[Jean-Luc Coulon (f5ibh)]

It seems that some informations are from the right lens and other for the
wrong one.
Probably these informations ARE in the file.
Maybe Sigma is trying to fool the Canon body to get some optical
corrections from it?

Hi Roman,

Thank you for your quick answer :-)

Ok. Is there then something I am missing or doing wrong since gdb cannot 
debug into other files than main.c? Is there a special trick?

You may want to
$ sudo mkdir -p /opt/darktable
$ sudo chown youruser:yourgroup -R /opt/darktable

And now when you do  ./build.sh --install  it will end up in there.

(Of course, you can pick any other directory, but then you need to
pass it e.g. via --prefix to build.sh)

[darktable-dev] Debugging of darktable.

[Jørn Villesen Christensen]

Hi there,

I have been trying to debug darktable (with gdb) but without any luck.

My main problem of running darktable from the build directory is that it 
will not load any modules. I have tried to play with --datadir, 
--moduledir, and symlinks, but without any luck. I can get the UI up 'n' 
running - but no modules are loaded.


Alternatively I have tried to install darktable in a temporary directory 
next to the build dir, but that fails as well. It launches well, but 
then gdb fails to debug any other files than main.c and I suspect it is 
due to the changed file structure.


So... is it possible for any of you to sketch up how you debug darktable?

yes, the correct name is "~" due to naming conventions that will
identify that as lower than 2.4.0 proper, so we can do release
candidates with the same number but still prefer the final version.
github very helpfully removes the ~ and replaces by . when you upload
the archive.
