Build Instructions not working...again

[kawfey]

Looked through the issues and couldn't find the reason for my build failure.

I would suspect that there is some issue with your librtlsdr headers. Can you provide more details (distro, installed packages,...)?

I would suspect that there is some issue with your librtlsdr headers. Can you provide more details (distro, installed packages,...)?

this is a fresh RasPi 3B+ running the latest Raspberry Pi OS, and librtlsdr installed from the osmocom library (apt install rtl-sdr) following these instructions.

I've tried it on WSL and a laptop running fresh Ubuntu 20.04 with the same error.

[KlemenBlokar]

Try to install all the packages from the readme.
sudo apt-get install libfftw3-dev libtclap-dev librtlsdr-dev pkg-config
You are missing at least librtlsdr-dev, I believe.

[kawfey]

I'm up to date.

It seems ubuntu (and debian) package of librtlsdr-dev is broken in version 0.6-1, there are numerous others that have trouble building against this version of librtlsdr-dev:
antirez/dump1090#142
merbanan/rtl_433#952
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=925916

Try installing a different version of librtlsdr-dev. I think it should work.

[KlemenBlokar]

Did you manage to build rtl-power-fftw?

[cwalker1969]

Hi guys! I've the same problem with the MalcolmRobb version of DUMP1090. I've tried others versions, without success. I'm trying to install DUMP1090 on a Raspberry Pi v1 B+ with Raspbian 4.19.118+ #1311. Finally, some DUMP1090 that works without compilation and build issues? Thanks!

[KlemenBlokar]

The problem is most likely not in the version of the software you are trying to build, but in the librtlsdr-dev package. Try to install a different version of that.

[KlemenBlokar]

Closing due to inactivity - issue seems to be with the dependencies, not rtl-power-fftw.

Just in case others are struggling with this issue, I too struggled, but found this workaround to be helpful (i.e., it worked)
