DronecodeSDK CMake Compiling Issue on Linux

MAVSDK

I am having trouble figuring out this issue. I’ve been trying every search and missing package and cannot solve this. I feel like there is something simple I am overlooking, any help is much appreciated. Note: I get the same error on any linux platform.

Here is the error message:
uaps@uaps:~/DronecodeSDK$ make default

Seems the issue is with Curl. This is the curl version I have:
uaps@uaps:~/SDK/DronecodeSDK$ curl -V
curl 7.52.1 (x86_64-pc-linux-gnu) libcurl/7.52.1 OpenSSL/1.0.2g zlib/1.2.11 libidn2/0.16 libpsl/0.17.0 (+libidn2/0.16) librtmp/2.3

Ok, I’m assuming you’re on Ubuntu 18.04.

So it says missing CURL_LIBRARY which means we’re not missing the binary curl but the curl library aka libCURL.

If you check the docs, you see that libcurl4-openssl-dev is probably missing.
I’m sorry that these docs are somewhat hidden, the plan is to have .deb packages to install soon instead of you having to compile this.

Another way to find out such dependencies, is to check how the Dockerfile is made which can be used to compile it as well.

I am running Ubuntu 17.04. Maybe that’s the problem?

I’ve also tried it on centOS version ? and raspbian version ? and got the same error on all.

This is the version of libcurl and openssl I have currently:

Also, I had tried “sudo apt-get install libcurl4-openssl-dev” and i get a 404 error.

I’ll try to update Ubuntu and see if that is the issue

If you can’t install this package, then it won’t work. And switching wildly Ubuntu versions or Linux distributions doesn’t make it any easier. Let’s try to fix the 404 and then continue from there.

If you haven’t updated the package index in a while, you might get 404 because apt-get is looking for an older version.

Therefore do sudo apt-get update and then try again.

Looks like it was an issue with Ubuntu 17.04

It has been compiled and running. Thanks for your time and attention. Looks like I’ve now moved on to other issues for another thread haha!
