GQRX Install on RPi5 Failing (SPDLOG)

[Michael Jackson]

For most of this day I have been trying to install GQRX on my RPi5 but get the following error when I command "cmake ..":

I have no concept of spdlog, its use or relevance to GQRX.  I do see that there is an expectation of a "{" character somewhere on line 168 of the /usr/include/spdlog/common.h file but I am not a programmer so I don't know the syntax.

Is there anyone who can decypher/assist?

If you use the version that comes with the Pi5, you should have no problem -

sudo apt-get install gqrx-sdr

That installs GQRXs 2.15.9 and it works with no problem on BookWorm.

If you insist on gqrx-2.17, you will have to grab the sources of all of the

versions of libraries that gqrx uses and build them . Using the latest 

versions of all the libraries would be your best chance, but that may fail.

Syntax errors at build-time usually indicate issues with preprocessor macros. Those, in turn, are often caused by build mismatches, for example trying to build on an unsupported platform, or with a library missing. 

Even for professionals, diagnosing and fixing such issues can be hard, especially without in-depth knowledge of the code being built. If you're not a coder yourself, I'd recommend a pre-built binary.
