Having trouble getting the stm vl53lx driver working on RPI

[DCamp.5]

Hi - I can't seem to get the driver to compile on a RPi 3+..

Grateful for any assistance !!

This is the error message I get:

pi@raspberrypi:~/VL53L3CX_LinuxDriver_1.0.5_bare_1.2.4/driver/vl53Lx $ make VL53LX_FULL_KERNEL=1

CONFIG_STMVL53LX=m make -C /lib/modules/`uname -r`/build M=$PWD

Something is really odd. I downloaded a fresh copy of STSW_IMG0021 and looked for start_tv.

it's not in there. Nor are there any instances of "_tv".

So I'm very confused.

I might consider starting over with a fresh download.

Hi John, thanks I did as you suggested but still have the same error. As per the error messages - most of these reference can be found in stmvl53l.h

[John E KVAM]

Seems there is a known problem compiling struct timeval with 5.x kernels:

https://github.com/draios/sysdig/issues/1609

I'm going to investigate what to do about it. I have not run across this before.

[John E KVAM]

Well it sure looks like you were right.

And it took my team a bit to solve it.

They had to rework a bit the deprecated timeval structure to make it work in both old kernel and 5.10.X

I2c_new_device function has been deprecated too, the modified files use i2c_new_client_device

Future releases will include these changes

Awesome - thanks for the support!
