Hi there!

I am just curious if this could be made to work with a USRP B210 device?

Hi,
I'm running ubuntu 18.04 / kernel 5.4 / both liquid-dsp & SoapySDR installed
I have RTL2832U dongle with Fitipower FC0013 tuner
First cloned your repo and used make (compiled successfully)
But after running fm_tune it says:
No devices found, using stdin
My dongle is connected and rtl_test, GQRX and etc works
Altough to test fm_tune i close every other program related to my rtlsdr dongle, so i'm sure i't available and that's not the case.
Any help would be appreciated.

When attempting to build on macOS 14 (Sonoma), the process kept failing because the compiler and linker couldn't find the Liquid-DSP headers or libraries. This was despite having the necessary packages installed (brew install liquid-dsp soapysdr).

The issue appears to be that the Makefile assumes that the paths returned by pkg-config for SoapySDR will also include the Liquid-DSP headers/libraries - but on macOS when using Homebrew, this isn't the case. Instead, the path returned is the specific folder in Homebrew's "Cellar" for SoapySDR (e.g. /opt/homebrew/Cellar/soapysdr/0.8.1_1/lib), which doesn't have anything related to Liquid-DSP for obvious reasons.

To work around this, I manually ran the compilation command (thankfully, there's only one) with the 'generic' Homebrew includes/lib paths (/opt/homebrew/include and /opt/homebrew/lib), which let everything compile happily. Said generic paths are just trees of symlinks to solve for this issue while allowing for multiple versions of a given app/library to be installed, to avoid Dependency Hell and the like.

As to a fix for the Makefile, I'm unsure of the best way, but an easy way would be to:

1. Test if a system is running a Darwin-based OS using uname
2. Test if homebrew is installed by running brew --env
3. If true, set SOAPY_CFLAGS to $HOMEBREW_PREFIX/include and SOAPY_LDFLAGS $HOMEBREW_PREFIX/lib in the Makefile.

In my case - and if anyone having similar issues on macOS runs into this issue - the working build command ended up being:

cc fm_tune.c -std=c99 -O3 -Wall -Wextra -march=native -I/opt/homebrew/include -lliquid -lm -L/opt/homebrew/lib -lSoapySDR -o fm_tune

Hi please help me have this error message after compiled the code
I put code into pastebin
