Problem

Building 1.39 from source fails to build with JSON-C support

Following these instruction:

including the section on preparing JSON-C

I have also tried installing the JSON-C package available from yum:

But the installer always exits with the following:

Hi @bergc !

Can you try again but this time installing the json-c-devel package?

Thanks!

Hey @Manolis_Vasilakis,

I installed json-c-devel and the build fails on --- **Compile netdata** --- with the following error: make: *** No rule to make target httpd/h2o/lib/http2/.deps/libh2o_a-stream.Po'. Stop.

json-c-devel info:

~/netdata (master) » sudo yum info json-c-devel

Ok, thanks. h2o was just added today, so it’s a new dependency, can you try a git submodule update --init --recursive --force ?

Running that command produces:

However running sudo ./netdata-installer.sh --enable-ml still fails with the same error.

So what I’m really after is getting v1.39 installed and being able to connect with Netdata Cloud, I went back and ran git checkout v1.39.0 and the sudo ./netdata-installer.sh --enable-ml is now successful. I’m assuming that was fixed by installing json-c-devel but am not 100% certain.

I think this can be considered resolved as I am not trying to build the most recent version available on master.

Thanks for your help @Manolis_Vasilakis!
