The gcc package seems to be a common requirement for installing and building some python packages. However this fails to install with the latest release of Venus (3.0) on a Pi3+
Hi Mike, the way you wrote above message suggests that you're sure its an issue on our side / opkg library side.
But, did you follow all required steps?

I do have gcc available to install, and a whole lot more.
success! Matthijs.
Bula Mathijs @mvader,
I tried just now setting the feed for opkg, previously this was left as is, after a clean install of V3.0.

exactly the same result.
BTW, did you catch my other post about the spi device being missing from the /dev folder when installing Venus on a Beaglebone black or Green?
ok thats good to know, and a bit strange: sounds like the issue is specific to gcc.
Can you try setting the feed to candidate, and then try again?
Those packages available from the candidate feed will work as well: other than some of our own code, nothing has changed between candidate and release (for now).
Here is my test, where gcc installed just fine. On a Cerbo, actually running v3.10~2, but installed it from the release feed. And note how the actual folder that it uses, cortexa7hf-neon-vfpv4 is also used for your rpi2.

This is on a pi3b+ (with Wifi).
Thank you @mvader, this looks like it will work. The normal Venus also gave an error using pip to install gpiozero, which resulted in a missing coloursys - but I don't think that this is your problem.
good to heat that its solved, or at least worked around!
Yes it did work, I can now load pip, gpiozero and RPi.gpio: However, coloursys is needed by /colorzero/conversions.py, and this cannot be loaded. The source code exists, but as it's not being used, I've patched it out for now.
Thanks again for your help, and keep up the good work. Victron does seem to be the only manufacturer that actually helps its customers!! (and also produce MPPT trackers with externally controllable current limit)
