Hey!

I am trying to build this project on an Nvidia Jetson AGX Orin which has an aarch64 based CPU. I am facing the following errors when I try to build it using cmake/make.

marmot@yunax:~/hebi-cpp-examples/build$ make
[ 14%] Built target _hebic++-obj
[ 14%] Linking CXX shared library libhebic++.so
/usr/bin/ld: /home/marmot/hebi-cpp-examples/hebi-cpp/hebi/lib/linux_x86_64/libhebi.so: error adding symbols: file in wrong format
collect2: error: ld returned 1 exit status
make[2]: *** [hebi-cpp-debug/CMakeFiles/hebic++.dir/build.make:104: hebi-cpp-debug/libhebic++.so.3.5.1] Error 1
make[1]: *** [CMakeFiles/Makefile2:1702: hebi-cpp-debug/CMakeFiles/hebic++.dir/all] Error 2
make: *** [Makefile:84: all] Error 2

Additionally, I also tried to build only one part of this project which is kits/daisy but still I face a similar error.

marmot@yunax:~/hebi-cpp-examples/kits/daisy/build$ make
[  1%] Automatic MOC for target hebic++

Please let me know if anyone needs any more information from my side.
Any guidelines to help resolve these errors are highly appreciated! :)

Thanks,

Thanks for the report! It looks like the documentation was out of date here; sorry about that.

I've opened a PR to update the README here: #80

Can you let me know if this helps solve the problem? Basically, just add

-DLIBHEBI_TARGET_ARCHITECTURE=aarch64

to the cmake command.

Yes! That worked :D

Thanks a lot @iamtesch!

Awesome! I'm checking to see when this regression happened; I'll either push a fix that allows the -DARCH to work as listed, or merge the PR with the updated docs indicating -DLIBHEBI_TARGET_ARCHITECTURE.

Thanks for confirming, and sorry again for the issue!
