Re: SeaLion (SeaMonkey / Borealis fork)
Hello, I just discovered this thread and your web browser,
I'm curious if It's possible to build SeaLion for linux ARM (aarch64) architecture. What would be the system and build requirements to do this?

Re: SeaLion (SeaMonkey / Borealis fork)
The build system / requirements are the same as Pale Moon’s. You can find that info here:
https://developer.palemoon.org/build/linux/
My build process is a bit crude compared to theirs.
1) Download SeaLion’s source code: https://github.com/wicknix/SeaLion/releases , then extract it.
2) Download the latest UXP: https://repo.palemoon.org/MoonchildProd ... P/releases
3) Extract UXP source.
4) Rename the extracted UXP directory to “platform” (without the quotes).
5) Move the platform directory in to SeaLions source directory.
6) Now you can follow the build instructions for Pale Moon. Also you’ll need to edit the included .mozconfig as needed for Linux.
Cheers

Re: SeaLion (SeaMonkey / Borealis fork)
The build fails with error:
It needs gconf, which is deprecated and not available in Debian 13 repos. I guess I'll have to compile in a Debian 9 system.
Also, I'm not sure if I configured the mozconfig correctly here, since I'm a complete newbie. Are these correct configurations for Linux arm64?
Code: Select all
