LimeSuiteNG installation errors reference SoapySDR

Projects Lime Suite
1

Hi all,

I am setting up a new Ubuntu 22 system and trying to port to the new LimeSuiteNG package. When building from source following the instructions within the repo readme, I get the following error when attempting to build:

CMake Error at /usr/local/share/cmake/SoapySDR/SoapySDRExport.cmake:80 (message):
The imported target “SoapySDR” references the file

 "/usr/local/lib/libSoapySDR.so.0.8.1"

but this file does not exist. Possible reasons include:

  • The file was deleted, renamed, or moved to another location.

  • An install or uninstall procedure did not complete successfully.

  • The installation package was faulty and contained

    “/usr/local/share/cmake/SoapySDR/SoapySDRExport.cmake”

but not all the files it references.

Call Stack (most recent call first):
/usr/local/share/cmake/SoapySDR/SoapySDRConfig.cmake:63 (include)
plugins/CMakeLists.txt:30 (find_package)

This is not an error I receive on my last installation run-through on another system. Has anyone had any issues with the API like that above?

Before building LimeSuiteNG, did you install SoapySDR from packages, or did you built SoapySDR from source?

3

I’ve rebuilt SoapySDR from source, and that seems to have solved the reference problem. I am now able to use the CLI commands for limesuiteNG successfully.

However, I am receiving an undefined reference to LMS commands when attempting to compile a simple C++ script, even when manually linking by -llimesuiteng.

So far, I have added /usr/local/lib to my path variable, but this did not solve the problem.

I appreciate any help; I understand that these are mostly generic linux questions not necessarily specific to building limesuite.

Post the console output from your attempt at linking - that should tell what the problem is.

If you did the install from source, “SoapySDRUtil -i” should show something like -

The console output from my attempt at linking is the following:

and if I output the verbose (“g++ my_file.cpp -llimesuiteng -v”)"

Using built-in specs.

LMS_GetDeviceList that’s legacy API, “liblimesuiteng” does not provide these functions directly. They are provided by “liblimesuiteng-legacyapi” wrapper.

What you need to do is -

g++ -o basicRX basicRX.cpp -llimesuiteng-legacyapi

Thank you, not sure how I missed that.

I appreciate the help as always!! Things seem to be working now.
