libRLRAudioPropagation.so mismatch causing build failure on aarch64 machine

[yichenzeng24]

Description:
I am trying to install sound-spaces on an aarch64 machine following the installation instructions from the official GitHub repository: Installation Guide.

However, I encountered an issue when attempting to install habitat-sim. It seems that there is a mismatch with the libRLRAudioPropagation.so library. The error occurs during the linking stage, as the library is compiled for x86_64 while I am on an aarch64 machine. Below is the specific error output:

/usr/bin/ld: /data/habitat-sim/src/deps/rlr-audio-propagation/RLRAudioPropagationPkg/libs/linux/x64/libRLRAudioPropagation.so: error adding symbols: file in wrong format

gmake[1]: *** [CMakeFiles/Makefile2:4827: esp/bindings/CMakeFiles/habitat_sim_bindings.dir/all] Error 2
gmake: *** [Makefile:136: all] Error 2

It seems that libRLRAudioPropagation.so is built for x86_64, but I am using an aarch64 architecture, causing the build to fail.

Steps taken:

• I followed the instructions from the installation guide to set up the environment.
• During the build of habitat-sim, the error occurred when linking the libRLRAudioPropagation.so library.
• The architecture mismatch between x86_64 and aarch64 seems to be the root cause.

Questions:

• Is there an aarch64 version of libRLRAudioPropagation.so available, or is there a way to rebuild this library for the aarch64 architecture?
• How can I properly resolve the mismatch to continue with the installation?

Thank you for your help!
