Hey Dave,

Perhaps one of the libraries we link against is different on this
platform. Can you try to set CMAKE_POSITION_INDEPENDENT_CODE somewhere
in the top level cmakelists? When it suggests -fPIC this is generally
the solution. Just like so:

> diff --git a/CMakeLists.txt b/CMakeLists.txt
> index c541a30..d29ebe2 100644
> --- a/CMakeLists.txt
> +++ b/CMakeLists.txt
> @@ -75,6 +75,8 @@ if(APPLE)
> set(CMAKE_MACOSX_RPATH ON)
> endif()
>
> +set(CMAKE_POSITION_INDEPENDENT_CODE ON)
> +

That should set -fPIC in a platform independent way. I will update the
build if this fixes it. Let me know!

Thanks, I put it in the following three files which I found were setting similar variables.   I have no "CMakeLists.txt" files.   The build completes, but Util doesn't run.

dave@tk1:~/SoapySDR/build$ find ./ -type f -iname "CMakeLists.txt"

dave@tk1:~/SoapySDR/build$ find ./ -type f -exec grep -il CMAKE_POSITION_INDEPENDENT_CODE {} \;

./CMakeFiles/3.3.2/CMakeCCompiler.cmake

Dave,

Ive no idea why its failing but I'm a little suspicious of the original
build erroring on linking. Maybe it picked up a static pthread library
or something unusual. Can you share the output of the cmake command and
the output of make VERBOSE=1?

-josh

I do regularly use soapysdr on debian armhf myself. FWIW

[Dave]

Please see attached.

I tried it on a 64-bit arm board (pine64):

Its probably not a library path that is searched by default. Try this:

export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
SoapySDRUtil --info

So the library path can be set in the bash profile like that, or more
permanently the path can be added for ldconfig:

If it also helps, another option is to change the CMAKE_INSTALL_PREFIX
and LIB_SUFFIX passed to cmake to something the system is already
looking for. Whatever works best~

Of course, that worked, thanks.  I shouldn't have tried it before having coffee.

But it's good it tried it, because after removing my original copy of SoapySDR and getting a new one from git, it also gave the same loading shared library error, in this case from /usr/local/lib.  No matter, now it runs.

But SoapySDRUtil finds no modules, factories, or devices.   There is currently an SDRplay plugged in and being controlled by another program.  Should Soapy have reported it?

Its probably not a library path that is searched by default. Try this:

export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH
SoapySDRUtil --info

Nevermind that, I've found the SDRplay module.  Thanks again.

I had the same problem and solution worked ...

My system is Armv7 Odroid-X2,Ubuntu 16.04 ...
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
