Unsupported file format or not RAW file

Hello I have a couple of photos that cannot be opened using Libraw. The photos are from a Sony ILCE-7RM5. Some photos from this camera LibRaw can open while others it cannot. I am using the libraw-dev version 0.21.3-r0 which should support this camera according to this document.

https://www.libraw.org/news/libraw-202403-snapshot

Does anyone have an issue that is similar or know what I might be missing?

Hey thanks for the response.

Hey thanks for the response. I think I've figured out the issue - libraw-dev version 0.21.3-r0 does not include the 202403 snapshot where the camera the photo was taken on is supported.

I am now trying to install and compile Libraw through master on Github. I'm doing this from an Alpine based docker image, after I clone the repo and run autoreconf --install I get the following errors

#10 22.66 configure.ac:16: error: possibly undefined macro: AC_SUBST
#10 22.66 If this token and others are legitimate, please use m4_pattern_allow.
#10 22.66 See the Autoconf documentation.
#10 22.66 configure.ac:41: error: possibly undefined macro: AC_MSG_WARN
#10 22.67 autoreconf: error: /usr/bin/autoconf failed with exit status: 1

Am I missing something, I'm following the installation from this guide here

This is messy crap with

This is messy crap with different versions of autoconf.
Use an older one or just build via make -f Makefile.dist (you may need to edit Makefile.dist to ajust build option)
