Trouble building FTL v6

AlexDumi29 · September 21, 2023, 8:03am

Expected Behaviour:

Successfully building FTL-development-v6

Actual Behaviour:

Trying to builld FTL v6 using the instructions over at Install from source - Pi-hole documentation. I built nettle 3.9.1 (tried 3.8.1 as well), and proceded to build FTL on the branch "development-v6". This is on Ubuntu Server 22.04, running inside virtualbox.

This is the output I get when running ./build.sh

As that's the development branch, and the one for the v6 release, I'd expect that it may not compile at all times.

What's your intention for compiling development-v6?

AlexDumi29 · September 22, 2023, 7:28am

I want to play around with the new REST API as I want to build a network security dashboard, and it would be nice to have some dials and lists with the most accessed websites, which hosts got the most blocked requests, etc. and would rather do it on the new API.

Bucking_Horn · September 22, 2023, 9:03am

Then you are indeed bound to use the development-v6 branch.

As an early adopter, you probably should be aware that the API is still subject to be changed without notice, especially since there has been no prior v6 release.

Do you still see those compile errors?

You may be missing libmbedtls-dev, which may be a v6 specific dependency (but I'm just guessing here), and there may be other more subtle dependencies for newer, more up-to-date packages as well.
(Note that the compile documentation currently only covers the requirements for v5. This will be updated with the release of v6.)

AlexDumi29 · September 22, 2023, 11:37am

Thanks for your response. I installed `libmbedtls-dev' and 'glibc-source' and now it goes further, but it errors out on 'generate-certificate'. How would I go about fixing this?

Ubuntu 22.04 provides mbedtls version 2.28.0 which is too old. FTL requires v3.x, the most recent release is v3.4.

Please see the pull request for the oncoming version v6.0 here:

https://github.com/pi-hole/docs/pull/338

and, more specifically, the updated documentation page here:

It is also important you get the latest libnettle from source as FTL v6.0 is using the secure password hashing function BALLOON which is a recent addition to the crypto library.

Thank you for all your help.

I've tried to build it again and I get an error, but it's fine, I'm just gonna deploy the Pi-hole preview docker image.

This is rather weird, I am not able to reproduce this. Using the docker container is likely the better option (it has all the necessary changes bundled into it). The solution would be what is suggested there, you'd need to manually modify the Makefiles of libmbedtls to achieve this.
