Building with Gitpod: How to enable Horussticks(Hall) and Mix-Scripts on X9E

[WillyZehnder]

With https://github.com/EdgeTX/edgetx/wiki/Building-radio-firmware-in-a-webbrowser-with-Gitpod by @rotorman
I have been building a 2.10.6 firmware for my X9E successfully.
But I have Horussticks installed and so some stick-directions are inverted.
I tried many different cmake -Wno-dev -D.. (e.g. HORUSSTICKS=Y, STICKS=HORUS, HORUS_STICKS=Y), but nothing led to the firmware option "horussticks".
So what I have to define for building a firmware with "horussticks"?

And further questions are:
What I have to define for enabling Custom(Mix)-Scripts on my X9E?
I don't need bluetooth, crossfire, ghost - so how can I disable that firmware options? (memory is a treasure at X9E)

Is there a file or a help where I can find the general info for all possible options for building?
cmake -LAH didn't work so I guess I've been in the wrong directory. So what is the correct directory to use that?

Thank you in advance for your hints

Generally each time you run cmake, you need to specify the directory that the source files are in, so when you are in your build directory, you need to add .. on the end (with a space separating it from the last parameter).

There are already options for X9E and X9E Hall (aka Horus) on Buddy, so there is no need to use GitPod if that is what you want, they are already built and available for download. But since it is there, you can take a peek at https://github.com/EdgeTX/edgetx/blob/2.11/tools/build-common.sh to see what the standard build flags used are.

In this case, you are are after the -DSTICKS=HORUS option / define. For the Custom Mixer scripts, you also need -DLUA_MIXER=Y. Custom mixer scripts are generally enabled by default for 2.11, but not for 2.10.x. The build may fail if there is not enough space / ends up too big, as 2.11 managed to save some space to enable more features by default.

Thank you @pfeerick, with your hints I could build a running version with Horussticks and Custom(Mix)-Scripts.
But I don't have an idea if the 5KB bigger bin-file (498KB) is a problem. Is that critical or if it fits to Flash all is fine?

I tried
cmake -Wno-dev -DPCB=X9E -DDEFAULT_MODE=2 -DSTICKS=HORUS -DLUA_MIXER=Y -DLOG_TELEMETRY=ON -DTRANSLATIONS=DE -DCMAKE_BUILD_TYPE=Release -UCROSSFIRE -UDSM2 -UGHOST ../
to get a smaller system, but that -U.. didn't result in a a system without CROSSFIRE a.s.o.
Is there a possibility to influence that? Maybe by editing a file?

[pfeerick]

If the firmware built without failing (i.e. overflow), it will be fine. Plus, smallest flash is 512kb, so that fits anyway.

That is the wrong syntax to disable a protocol... not sure offhand what is correct there... (not at PC atm) ... might be -DCROSSFIRE=N

I tried -DGHOST:BOOL=FALSE and -DCROSSFIRE:BOOL=FALSE and -DDSM2:BOOL=FALSE
Disabling DSM2 is not allowed when multimodule is enabled - i've got a warning.
Disabling GHOST is working and saving 3KB,
but to disable CROSSFIRE is generatin errors. It seems to me, that nobody tried that out in the past, because it's not really necessary. To generate a waterproof code, that should be tested automatically in future versions.

Thats my final build-line that generates the code I wanted to have:
cmake -Wno-dev -DPCB=X9E -DDEFAULT_MODE=2 -DSTICKS=HORUS -DLUA_MIXER=Y -DTRANSLATIONS=DE -DCMAKE_BUILD_TYPE=Release -DGHOST:BOOL=FALSE ../

Thank you all for that quick help and support :o)
