Compile on GL.iNet GL-SFT1200

[warwound]

I'm trying to compile ddserver on my GL.iNet GL-SFT1200 router.
https://docs.gl-inet.com/en/3/specification/gl-sft1200/
The router runs OpenWRT and has a MIPS SF19A28 CPU.

git clone git://github.com/hubaiz/DslrDashboardServer package/DslrDashboardServer

fails but this next one works:

git clone https://github.com/hubaiz/DslrDashboardServer package/DslrDashboardServer

I then run:

make menuconfig

and get:

make: *** No rule to make target 'menuconfig'. Stop.

If I move into the 'package' directory I get the same result when I run the same command.
And if I move into the 'DslrDashboardServer' directory and run the same command I get:

Makefile:13: /package.mk: No such file or directory
make: *** No rule to make target '/package.mk'. Stop.

My 'package' directory in locate at:
/root/package/DslrDashboardServer

Is OpenWRT expecting my package directory to be somewhere else and that is required in order for the 'make menuconfig' command to succeed?

You need to setup an OpenWrt development environment, here you find instructions for it: https://openwrt.org/docs/guide-developer/start

Ah that explains it!

Your link to the OpenWrt developer docs talks about installing a development environment on say a PC and using cross-compilation to compile a binary for the target device - my MIPS router.
Is that the only way to proceed?
Is that the recommended way to proceed?

Is the 'package' directory I mentioned above part of the OpenWrt source and I need to (re)compile OpenWrt with ddserver embedded in it (I hope this is not the case)?

Can I instead simply install some development packages on my router and compile on my router?
This must be the most elegant solution.

Sorry but I'm not an OpenWrt expert. I installed the complete development environment and did the build that way. Eventually you could try the SDK and build with it but don't know if it will work and I can't help you with it as don't have any experience with the SDK.

OK thanks a lot - you've pointed me in the right direction. :-)

I got it working - far easier than I'd ever imagined...
GL.iNET have their own version of the OpenWRT SDK in their github repo:
https://github.com/gl-inet/sdk
On my Mint laptop I installed a few dependencies (the above link shows Ubuntu 18.04 packages to install, one or two needed a rename).
Cloned ddserver into the right folder:
sdk/1806/siflower/package
The command 'make menuconfig' now works.
And the GL.iNET webpage shows how to compile a standalone binary for my GL-SFT1200:

cd sdk/1806/siflower/
make package/DslrDashboardServer/compile V=s

This needed a couple of tries before I got it working.
The result was a file 'ddserver_0.2-14_mips_siflower.ipk' of less than 12KB which I transferred to my router and installed using the opkg command.
Connected my Nikon D5300 and it works perfectly, I can abandon the Pi Zero I was previously using to run ddserver.
