Re: [Paparazzi-devel] paparazzi secure datalink compile errors.

[Gautier Hattenberger]

Hi,

This rust code is old, that explain the 'deprecated' warnings.

But for the actual error, it needs the hacl C library, which should be 
compiled by rusthacl I guess, but it is not done. So it needs to be 
compiled and install by hand.

In your dev folder do:

git clone https://github.com/paparazzi/hacl-c.git
cd hacl-c
make
sudo cp libhacl.so /usr/lib

After that, it should compile the rust link agent. But the best would be 
to understand why it is not compiling correctly in the first place (and 
eventually fix the warnings) but I'm not expert in Rust and Michal who 
made this code doesn't seem to maintain it anymore. Maybe you can still 
ask him directly for assistance. Also, rusthacl alone is just compiling 
correctly.

Cheers

Gautier
