Can Receivers work on ARM?

[daiaji]

In fact, my USB stereo can't save the volume configuration on Linux (reconnecting it to a very small initial volume after power failure) I had to keep the USB sound working. But fortunately, I bought a ARM development board before, though its Linux kernel has some minor problems. Can I cross compile Receivers for the ARM development board?（I have no experience with that）

Yes, compiling should work out of the box if you have the necessary dev packages installed with your toolchain (pulse or alsa development packages).

@duncanthrax While the process of building the kernel is quite painful But I try to build receivers and report after I've built the kernel and rootfs.

@duncanthrax I don't know what to do.

aarch64-linux-gnu-gcc -Wall -o scream-pulse scream-pulse.c -lpulse-simple -lpulse
/usr/lib/gcc-cross/aarch64-linux-gnu/8/../../../../aarch64-linux-gnu/bin/ld: cannot find -lpulse-simple
/usr/lib/gcc-cross/aarch64-linux-gnu/8/../../../../aarch64-linux-gnu/bin/ld: cannot find -lpulse
collect2: error: ld returned 1 exit status
make: *** [Makefile:5: scream-pulse] Error 1

You need to provide the pulseaudio static lib (libpulse.a and libpulse-simple.a) files. Those also need to be built for the same arch (ARM).

If you already have those, GCC might not find them. Add an -L parameter to the gcc call in the Makefile to point to their location.

@duncanthrax In fact, I gave up cross compilation. It doesn't seem so slow to compile Receivers on ARM devices. After installing pulseaudio, scream-pulse seems to be able to run. But then I found that my kernel didn't seem to have sound card drivers, so I had to rebuild the kernel.😰

@duncanthrax After I gave up compiling scream-pulse and compiling scream-alsa, Scream-alsa works very well. But I found out at the same time, if so, how can my Host play the audio? But at least scream-alsa can work on Ubuntu arm64. Thank you😋

Receivers throws up some mistakes. But Receivers is working.

Solution: Use stream receiver in raw mode outputting to snapserver's pipe, then on the raspberry use just snapclient. No underrun! Moreover you can connect many snapclient you want and enjoying multiroom synced audio.
