Issues building Citra on ARM

Issue:
Build process fails at 94% with ’ template argument deduction/substitution failed" (among others)
I’ve included everything I can think of that’ll help. I’m no programmer.

System Information

  • Operating System: Debian 10 w/ kernel 4.19
  • CPU: ARMv7 Processor rev 4 (v7l)
  • GPU: Broadcom Videocore-IV
  • Citra Version [Nightly Build - c4a4b40]
  • Game: N/A
  • Screenshot of Issue (include the full Citra window including titlebar):
    See below for build output

In order for us to provide better support, we need to see the log generated by Citra. This guide will walk you through how you can obtain the log file: How to Upload the Log File.

No log available. The issue is during the build process. Anyone human have any input?

I’ll bump this - I am stuck here as well. I’ve seen reference elsewhere that this is actually a linker problem. I have no idea if this is correct.

The other issue someone will hit first is the need to explicitly link with libatomic on raspbian buster. I had to add the dependency as compiler arguments to the cmake buildfiles.
