You don't have the SoapySDR library installed.
I do, but still got some error and can't compile.
Sorry, I haven't noticed this issue for a while. Please check with the latest master. It should use pkg-config to detect the correct paths. (6c62d27)
If it doesn't work, please post your config: what system are you using, is the soapysdr installed from a package, or from source. If from source, what's the install location?
You can also override the options on your own now with:
make SOAPYSDR_LDFLAGS="-lSoapySDR -Lyour/soapy/libs/path" SOAPYSDR_CFLAGS="-Iyour/soapy/include/path"
Closing for now. Feel free to reopen if that didn't solve the issue.
I'm getting exactly the same results as dave-88. Confirmed that the makefile has the pkg-config changes. Tried with Soapy SDR installed from package and also built from source, with same results.
Question: Your "orverride" make command sets SOAPYSDR_LDFLAGS and SOAPYSDR_CFLAGS. Should these actually be SOAPY_LDFLAGS and SOAPY_CFLAGS, the variables used in the makefile?
You're right, the override version should be:
make SOAPY_LDFLAGS="-lSoapySDR -Lyour/soapy/libs/path" SOAPY_CFLAGS="-Iyour/soapy/include/path"
@adrianboyko Could you post which OS/version are you using and what's the result of running pkg-config --cflags --libs SoapySDR
I have the same issue, my OS is Ubuntu 19.10 and I've tried compiling using this command cc -std=gnu11 -O3 -Wall -Wextra -march=native -lliquid -lm -lSoapySDR fm_tune.c -o fm_tune and it finds the libraries without any problem but I get linking errors saying that it cannot find some SoapySDR functions. I have these packages installed libsoapysdr-dev libsoapysdr0.6 and I get the same error even when I explicitly tell the gcc to link with /usr/lib/x86_64-gnu-linux/libSoapySDR.
My SoapySDR lib package is exactly this libsoapysdr-dev/eoan,now 0.6.1-4 amd64.
Yeah so I figured out the problem, it seems like that the GCC resolves the linking order based on the position of the arguments, so the translation unit that uses a library must be specified before the library is specified. So this would be the correct command
cc fm_tune.c -std=gnu11 -O3 -Wall -Wextra -march=native -lliquid -lm -lSoapySDR -o fm_tune
notice how the file name is before the libraries. This fixes the problem for me. And this is the wrong command that the make command produces: cc -std=gnu11 -O3 -Wall -Wextra -march=native -lliquid -lm -lSoapySDR fm_tune.c -o fm_tune
Also I've noticed that the GCC that is provided with some distros is okay with the order of the arguments being wrong.
