build problem on Ubuntu 24.04

[j75]

Hi!

I'm trying to build the application on Ubuntu 24.04 (and waiting for the AppImage...) and I stumble on the following errors:

/usr/bin/ld: CMakeFiles/swradio-9.dir/decoders/drm-decoder/equalizer/equalizer-1.cpp.o: in function `equalizer_1::equalize(std::complex<float>*, short, myArray<ourSignal>*, float*, float*, float*, std::vector<std::complex<float>, std::allocator<std::complex<float> > >&)':
/.../decoders/drm-decoder/equalizer/equalizer-1.cpp:403:(.text+0x2217): undefined reference to `estimator_2::estimate(std::complex<float>*, std::complex<float>*, std::vector<std::complex<float>, std::allocator<std::complex<float> > >&)'

Any idea how to fix that?

Another error message:

I uploaded the sources of the version that I am using, and that compiles fine under Fedora and U20

OK, so it should be built on Ubuntu 20.? Anyhow, the AppImage works on U24.04 so I can hereby declare the case closed.

The swradio compiles fine on U20 and U22 - I do not have an U34 installed. It is annoying that it does not seem to compile on U24. Can you send me the output of what is generated when trying to build it
