How to compile for RaspberryPi?

[TIMAI2]

The original deb file from Art Tevs dies on the first line with 'unexpected "(" '

How do I compile openBM for a raspberry PI, specifically libreElec image

Thanks

[harryberlin]

LE is a very downsized readonly OS. I mean you should try OSMC.

[TIMAI2]

So the original deb file I have for openBM should work on an raspBerry Pi ? Agree that LibreElec is sparse :)

[harryberlin]

i mean you have to compile at raspberry pi.

OK, getting stuck with cmake ../

I had to change all references to /home/tevs/src/OpenBM to /home/osmc in CMakecache.txt

Then cmake ran but... This fails on pthreads and lpthreads - CMakeError.log below

Determining if the pthread_create exist failed with the following output:

Making progress, cmake ../ command now working after installing the libboost dependencies

Running make I get the following errors:

All / Any help most welcome :)

Same here

[harryberlin]

do you have to place "io_" before service?
