Hello, I'm new to INDI development. I'm trying to build my first driver following the tutorial step by step but I'm experiencing some issues.
If I CMAKE as in tutorial I got the following:

-- The C compiler identification is GNU 6.3.0

If I try to CMAKE in the examples/tutorial_one folder the CMAKE works fine, withour errors, but I can't install (make install):
make: *** No rule to make target 'install'. Stop.

Can anybody help me? I'm probably missing something important...
Thank you very much

Which tutorial are you following?

A tutorial that I found on this forum about a similar topic. The same that you find at the following link:
indilib.org/develop/tutorials.html

I forgot something: I'm working on VM ekos

Thank you

Install pre-requisites:

Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'libgsl-dev' instead of 'libgsl0-dev'
Package libcfitsio3-dev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libcfitsio-dev:i386 libcfitsio-dev

E: Package 'libcfitsio3-dev' has no installation candidate


I try to follow the suggestions

I've done what the apt-get said. now it's working!!
Thank you!
