Thanks Eric, building directly on the Voxl2 platform works.

@Eric-Katzfey

I tried it based on this project

but it need a CMakeList.txt for it to compile. I did build other third party library succesfully, but building libusb from source file does not provide a CMakeList.txt, at least from their github. The only way they sugesst to install is with apt.

Is their a way to build from source without a Cmakelist.txt file ?

Hi,

I am having an issue with compiling a library with voxl-cross and runing it on the Voxl2 board. I did compile on voxl-cross but when I try to run a programme that use the library. I got an error with libusb :

voxl-tcp-neuro: symbol lookup error: /usr/local/lib/libcaer.so.3: undefined symbol: libusb_set_log_cb

After a researching on google and asking AI chat bot. I found that the version of libusb on the Voxl2 board is 1.0.21 in contrast to 1.0.27 on voxl-cross. The result is that libusb missing libusb_set_log_cb.

I tried to update the version on Voxl2 but I did not succed because 1.0.21 is the latest version availible on ubuntu 18, but voxl-cross seem to run ubuntu 24.

Is there a way to make it work ?

Ok thanks for you clarification, I will try it and see how it goes.

Hi,

I would like to use a third party library to interface my sensor with voxl2, but I don't find the documentation on how to add a new library on voxl-cross.

I assume to be able to run on voxl2 it need to be compile with voxl-cross. Am I correct ? I also try and build directly on the voxl2 with cmake over adb but the performance are much lower than using voxl-cross (I run a c programme that compute the 50th first pi decimal just for test).

What would be the best path to make it work ?

The library I look to use is libcaer for inivation sensor. https://gitlab.com/inivation/dv/libcaer

Thank for your help.
