I think this comes from here: https://github.com/LibRaw/LibRaw/blob/b31fa58eea272c4ba67ccdbd527f329a5a...

_WIN32 is defined even on Cygwin, but I guess one shouldn't set LIBRAW_WIN32_CALLS on Cygwin; as a consequence, unistd.h is not included from internal/defines.h: https://github.com/LibRaw/LibRaw/blob/master/internal/defines.h#L50-L65

Any reason you're building for Cygwin, and not native MinGW instead?

Hi support,
More details, I am using the GNU compiler Collection c++ gcc-g++ version 11.2.0-1.
Whatever i try, the swab function causes the problem: not declared in this scope.
Thanks,

Hello Alex,

I use Capture One 21 (I am aware that 22 should support the Sony A7IV).
And I use Affinity Photo 1.10.4.1198 (Photoshop replacement). Affinity support says their software depends on LibRAW for camera support... Yet, FastRawViewer 2.0 already seems to support the camera already.
And I use darktable 3.8.0 (both Windows and Linux).

Thanks, Eric.

Hello, any idea when the Sony A7IV will be added to the library?
It turns out some of the editing software I use, used LibRAW to read the raw files. Until that is updated, I can't edit my raw files in those...
Thank you!

Thanks - the rawpy folks mentioned the terminal output all looks fine, but that perhaps I should try again and enable the RPi RAW support. When compiling LibRaw I made the folder ~/Desktop/libraw into which I cloned the LibRaw repo.

- Can I remove that folder and try compiling again, or were LibRaw files installed elsewhere that need to be removed?
- In the future, what folder do you recommend I clone the LibRaw repo into?

Thank you for the reply. I followed the instructions (below) provided by rawpy (which uses LibRaw), as suggested by Iliah Borg (see further up for this discussion). Should I instead follow the LibRaw provided instructions?

git clone https://github.com/LibRaw/LibRaw.git libraw
git clone https://github.com/LibRaw/LibRaw-cmake.git libraw-cmake
cd libraw
git checkout 0.20.0
cp -R ../libraw-cmake/* .
cmake .
sudo make install

Hi - I just wanted to confirm I installed from source correctly. Below is the terminal output resulting from my cmake command. As you'll note, it indicates a few files were not found. Additionally, can I remove the ~/Desktop/libraw folder I created to clone the libraw repo?

LibRaw works fine on Apple M1 ARM chip

> it seems LibRaw can be installed on an RPi

Why "seems", I checked with my RPi before posting.

Which method of installation to use depends on your needs.

Generally if you want a package (rawpy in your case), it's a good idea to follow the instructions accompanying the package, especially when those instructions refer to a particular (not the latest) version of a library. You will need to install git and cmake,

> sudo apt update
> sudo apt upgrade
> sudo apt install git
> sudo apt install cmake

After LibRaw is installed the way rawpi instructions suggest, check

> echo $LD_LIBRARY_PATH

If it's empty, and you want to use LibRaw independently / check the installation:

> LD_LIBRARY_PATH=/usr/local/lib
> export LD_LIBRARY_PATH

My apologies re. "seems" - I did not intend to cast doubt on your reply. Thank you very much for all the helpful information, and for checking these installation instructions on your own RPi - that is greatly appreciated! I am looking forward to using LibRaw.

Thank you for the helpful information! So it seems LibRaw can be installed on an RPi - this is great!

Just to clarify, in the case where both options are available (apt install or compiling), is there a reason why I would choose one over the other (e.g. will the compiling option give me a newer version)?

Additionally, re. compiling, I found these instructions on rawpy's website (a package I'm hoping to use), which look similar to the instructions you provided above, but there are some differences - will either set of instructions work?

git clone https://github.com/LibRaw/LibRaw.git libraw
git clone https://github.com/LibRaw/LibRaw-cmake.git libraw-cmake
cd libraw
git checkout 0.20.0
cp -R ../libraw-cmake/* .
cmake .
sudo make install

Thank you for your help.
Than I there is another issue related to the Java wrapper - Sorry for that. The output_color=0 was already commented out therefore was never active (leading slashes).

I have now removed the options and use the lib with the default options. After JDK18 I have to generate the sources from the header file again and will see if that helps.

Nevertheless under windows I had troubles with ljpeg-8d which is not compiling. For now I have removed libjpeg from all builds because it is not so important for the users.
