Runtime Error on aarch64 System

[roboticszeng]

Hello,

I'm experiencing a runtime error when attempting to execute the ruckig repository on an aarch64 system. The repository compiles successfully, but when I run the example-01 test case, I encounter the following error:

./example-01_position: symbol lookup error: ./example-01_position: undefined symbol: _ZN6ruckig11CloudClientC1Ev
I have not made any modifications to the code and am running the test case as is.

Here are the details of my system:

uname -a output:
Linux ubuntu 5.10.120-tegra #1 SMP PREEMPT Tue Aug 1 12:32:50 PDT 2023 aarch64 aarch64 aarch64 GNU/Linux
I would appreciate it if you could provide guidance or a fix for this issue. Thank you for your time and assistance.

Best regards!

The compiler seems to have failed to pick up the cloud_client.cpp sources. Can you check that this line is executed by CMake. Do you have disabled the BUILD_CLOUD_CLIENT variable?

i dont change any line of this CMake, just build follow the step in README.md

[roboticszeng]

program crash in this line:
while (otg.update(input, output) == ruckig::Result::Working)

@roboticszeng if you still have this issue, you could try my solution propused in #198 .
I had a similar issue, also an issue with a reference to ruckig::CloudClient.

Sorry for the late response. I'd assume that this error comes from a mismatch of the header files and the linked library, e.g. you have installed ruckig system-wide, but now compile

Hi @roboticszeng - sorry for the late response. It seems that the linker is picking up a shared library that was compiled with the BUILD_CLOUD_CLIENT=OFF flag. Did you install Ruckig system-wide?

You could...

• compile Ruckig yourself, e.g. by using CMake's add_subdirectory or following this example.
• set the flag BUILD_CLOUD_CLIENT=OFF for your build - assuming you don't need that feature.
