Dear all,
Very unfortunately, Darktable (DT) fails to work for me. When I have
worked a picture in DT and switch to lightroom mode, I get the message
"/failed to allocate memory for export/, please lower the threads used
for /export/ or buy more memory." The (raw) pictures have a size of
approx 40-50 MB each (Nikon D800). I also get the message when I have
only 1 picture loaded.I also enabled only 1 thread for export. With my
previous camera (Nikon D200) who produces much smaller images I have
used DT successfully.
My system has 24 GB of memory. I can't believe that this is insufficient.
I am using the head of the git repository, so in a way the latest version.
I tried to spot the problem a bit more by compiling DT in debug mode. I
found that the routine dt_dev_pixelpipe_cache_init() in
pixelpipe_cache.c has the line
cache->data[k] = (void *)dt_alloc_align(16, size);
(where size is 580 953 216, or 0.6GB)
which fails after being called several times.
This happens, however, when the total memory usage (according to the
utility xosview) is roughly 7 GB.
I have no knowledge about how DT works. Is there any developer how can
help me out?
Kind Regards,
Bertwim
