Errors with compile on RPi with Tiny Core Linux

[Twist]

Hi there!
I'm trying to compile OpenCPN on a Raspberry Pi running Tiny Core Linux. But I'm running into an error and I don't know the solution (yet).

Grabbed the OpenCPN 4.8.4 tar sources from github
Using PiCore (Tiny core) 9.0.3 ( Linux - 4.9.22-piCore-v7 - armv7l )

Running cmake is succesful after adding a symbolic link to make the wx header files findable.

A little while into make -j3 I get the following errors. Any help would be much appreciated!

(red color my emphasis: )

I can mannually run the offending cc line when I remove the -msse2 option.
But when I invoke make -j3 again, it will still redo the cc of lz4 with the -msse2 option. Do I need that option? And where/how do I switch it off?

Most people must run Openplotter on a Pi these days?

Runs on stretch now, extremely powerful and well supported.

I'm aware of OpenPlotter, but like the tiny footprint and other features of tiny core linux. Hence my attempt to compile from sources.
I just found this thread as well where 'tiny pilot' (sd image of just 60MB!) is mentioned.

OK, though don't really see the point apart from some fun getting it working, if you have a Pi 3, it can easily handle openplotter with Opencpn and signalk plus all the other useful stuff it does. Mine stays on 24/7

Twist....

The -msse2 option should only be invoked on x86 systems. So somehow the CMake recipe is incorrectly identifying your system architecture.

Let's see the output of a cmake invocation from scratch. Looking for:

"*** Build Architecture is ${ARCH}")

thnaks bdbcat, you're absolutely correct, as I found out...
I'm learning as I go along. cmake checks for a couple of known linux distributions (not tiny core) and choses i386 otherwise.
I forced it arch to arm64 (or should that be armhf???)

The next problem then is wxWidgets as supplied by tiny core is compiled without OpenGL suppurt.

I may postpone my attempts until tiny core 10.x is released (currently in beta) so I can swicth to using a RPi3B+
Looks like I will have to compile wxWidgets, which I understand may take a while...

Just for the sake of it I've now set OpenGL to OFF in de cmake config and am trying to make opencpn without GL support.

[bdbcat]

Twist...

I would select "armhf" as your arch target.

Don't fear compiling wxWidgets. Takes a couple of hours, but usually no problems with the correct config setup.

Keep us posted, and we can correct the CMake recipe for your distro.
