I compiled LHDR from github today, and since it relies on lbraw, I thought it could work on Fujifilm xtrans raw files. So I tried to load 4 of such files from my Fuji X-T2, the program didn’t complain but… despite the the CPU meter showing around 50% of use by LDHR, I waited many minutes but nothing seemed to happen, the “HDR creation wizard” showed “loading” and the progress bar stayed at 0% (and hitting teh “cancel” button does nothing).
Are xtrans raw files unsupported? If it’s the case, it would be nice to get some message informing the user that their raw files are not supported, and have the program stop there.
Which version of LibRaw is LHDR linked to? Latest 0.19 LibRaw 0.19 should support x-trans better. Check whether your camera is supported from Help->Show Supported Cameras. My next task is to improve raw import with 0.19 and LibRaw in general.
@fcomida LHDR is linked to LibRaw 0.19.0 installed from the official repository of my distro (Manjaro Linux). Ther Fujifilm X-T2 is listed as supported, but for whatever reason it makes LHDR stall when I try to load X-T2 files.
Edit: my problem is more serious, it fails to load Pentax and Nikon files. I get the followin in the console:

@sguyader you can attach GDB to the running process, then get a stack backtrace to see where it’s stuck.
Here’s a gdb output from just running luminance-hdr:

Is noise reduction in lhdr enabled? If so, disable it.
Even pef files don’t load after turning it off?
Indeed even PEF’s won’t load. I made a fresh cloning and compiling from github, still the same.
LibRaw 0.19 has issues with Luminance HDR. I have other reports of errors or even crashes.
My build on Fedora 29 on a VM behave strangely, it crashes at the very first attempt of reading any raw or tells the raw file failed to being read , but then, afterward it works!!!
As I said my next task will be make LHDR working with LibRaw 0.19

@fcomida Do you know if the problems are valid even for the latest beta builds of LibRaw? Otherwise I can try compiling it from the current source code.
@sguyader I have no idea. Since you are building LibRaw and LHDR from source why don’t you stick with 0.18 for now?
I have other programs that rely on LibRaw, installed from my distro’s official repo. Downgrading to LibRaw 0.18 would mean downgrading those programs too
I was just suggesting trying temporarily to link LHDR again the latest beta of LibRaw to see if it would fix the problem.
I’ll try to see if the appimage package has the same problem.
Yeah dependencies are a problem.
That’s crazy: I run LHDR linked to 0,19, read any RAW file → error!!!
Then I open a HDR (EXR, RGBE) or create a HDR from Jpegs, close the HDR and open a RAW again → IT WORKS !!!
Can you confirm this?
No I can’t confirm, I still can’t load raw files (I tried RAFs and PEFs) even after successfully generating an HDR image from raster images.
I am quite sure the issue is somehow related to the removal from 0.19 of GPL2 and GPL3 demosicing algos (AMAZE and others). LHDR build system will detect their absence and deal with that (in the GUI for example). Not sure if the configuration is updated though. Can you check the settings? …while writing this I indeed checked “Luminance HDR.conf” and “user_qual” field (demosicing method) is not updated, Either edit the file or change it from the GUI Settings. This way the first attempt still fails but then it works again 
I’m not sure I understand what you ask me to do. In Luminance HDR.conf I have this:
[Raw_Conversion_Options]
TK=6500
aber_0=1
aber_2=1
auto_bright=false
brightness=@Variant(\0\0\0\x87?\x80\0\0)
do_not_use_fuji_rotate=false
four_color_rgb=false
green=@Variant(\0\0\0\x87?\x80\0\0)
highlights=0
level=0
med_passes=0
threshold=@Variant(\0\0\0\x87\x42\xc8\0\0)
use_black=false
use_chroma=false
use_noise=false
use_sat=false
user_black=0
user_qual=3
user_sat=20000
wb_method=1
So, I guess user_qual=3 means AHD demosaicing algo. What should I change it to?
I tried to set the demosaicing algo to bilinear, processed an HDR image from EXR, saved the result, and tried this in the same session:
- to load 3 PEFs → failed
- to load 3 NEFs → success
- to load again the 3 PEFs → success
- to load 4 RAFs → success → saved the output, closed the HDR file
- to load again the same RAFs → failed
Go figure what’s going on… 
For now I only know it isn’t working and must be fixed in the next LHDR release.
