Compiling errors

[sippe2]

Hello,

Any idea how to solve these problems?
I'm trying to compile with latest openwrt repo under Ubuntu 16.04. It's almost impossible to find MR3040 or MR11U board so it would be nice to make ddserver image to another hardware platform like A5-V11.

Thank you.

I have now A5-V11 binary image and system works under 15.05.1 pretty well. It was little bit tricky to fit everything to tiny 4MB SPI ROM so I had to remove PPP support. I think it's not big deal.

A5-V11 binaries
OpenWRT Chaos Calmer 15.05 with ddserver support

A5-V11 factory binary

A5-V11 sysupgrade binary

Default ip is 192.168.1.1 with no password.

Configure network, wireless SSID and LEDs the way you like and remember to change password.
Perhaps the easiest way is use 192.168.1.0/24 network because DslrDashboard looks ddserver under 192.168.1.1.

Here is more information about the unbranded A5-V11 board.

This unbranded Ralink/MediaTek RT5350F-based router is sold on Aliexpress and Ebay from Chinese sellers for around 6 USD (shipped) as of July 2016. It has a tiny black or white housing about the size of a lighter, with silkscreened print "3G/4G Router 150M".
There is also Ralink/MediaTek RT5350F-based portable routers with 1800mAh and 5200mAh powerbank for around 16 USD. It has tiny white box with blue, green or orange stripe on the side. Top of the box there is silkscreened text "3G Wi-Fi Router" or "3G/4G Wi-Fi Router".
