Build From Source Failure (Raspbian OS) #2374

Closed codymarquardt closed 1 month ago

codymarquardt commented 1 month ago

I have a raspberry pi 4 running Raspbian (Linux 11 Bullseye). I want to build mavsdk from source so that I can have full control over debugging and making changes to the source.

I followed the tutorial from (https://mavsdk.mavlink.io/main/en/cpp/guide/build.html) and have run cmake to get the errors shown below. The output log is also shown below. I have tried building the mavlink third_party library separately and that was not successful either. Am I not going to be able to build this on Raspbian?

Error: could not load cache

This sounds like it's not a clean build. Is this the output of a clean build?

codymarquardt commented 1 month ago

I cleaned off the build from scratch and that fixed the load cache error. Now, it is giving me this

JonasVautherin commented 1 month ago

Which version of CMake are you running?

codymarquardt commented 1 month ago

version 3.18.4

JonasVautherin commented 1 month ago

It seems like you need at least CMake 3.19 because of this in mavlink/libevents :shrug:

codymarquardt commented 1 month ago

I suppose I could try installing cmake 3.19 from source. Is that the easiest in your opinion?

JonasVautherin commented 1 month ago

Not from source. Just download a binary from https://cmake.org/download/ :blush:.

julianoes commented 1 month ago

Also, this doesn't look right. Have you installed some sort of cross compiler GCC manually?

codymarquardt commented 1 month ago

I am using BlueOS, so I cannot confirm if it is or not

By updating cmake to 3.19, that fixed my issue there. There now seems to be an issue with GTest::gmock. I installed libgmock-dev already

I found a post discussing this exact same issue on the PX4 forum with no fix

JonasVautherin commented 1 month ago

Can you try building MAVSDK without the tests? I made a PR here to allow that: https://github.com/mavlink/MAVSDK/pull/2377.

You should be able to build with -DBUILD_TESTING=OFF :+1:.

codymarquardt commented 1 month ago

Hi Jonas,

That is actually what I ended up doing!

Thanks for the help. I think we can close this
