you have an issue with some dependencies. That is not a problem related to siril but to your installation.
OK, hmm, yeah, well, hmmm....thank you. But then the problem is: I followed all the instructions, I have all mandatory stuff installed, and as I most probably know much less about the requirements than you/the developers, or, to be exact, nothing :-) :-( , then there's no way for me to find out more ...
BTW: I cloned the git repository, then installed all required tools and libs mentioned in the README, ... - and compiling don't work either, it stops already at the configuring stage with following message:
**Warning**: I am going to run `configure' with no arguments.
If you wish to pass any to it, please specify them on the
`./autogen.sh' command line.
+ aclocal --install
+ intltoolize --force --copy --automake
./autogen.sh: 23: ./autogen.sh: intltoolize: not found
+ exit 1
To conclude, well, its free stuff so I can't demand anything, but when I follow all the instructions and it still doesn't work, the the answer 'its a problem with your installation' is probably technically correct, but practically of not much use :-) :-(
But no problem, don't worry, there are other tools out there, I'll have a look a them ...
