Building on Raspbery PI

[KHjerrild]

Hi I'm trying to build the RTL_433 on my raspberry pi. I already have the RTL-SDR running.
I used the build commands described in BUILDING.md
git clone https://github.com/merbanan/rtl_433.git
cd rtl_433/
cmake -B build
Complains that build dir doesn't exist

Trying this one instead:
mkdir build && cd build && cmake ../ && make

Works fine until CMake Error at CMakeLists.txt:104 (if):

I have attached my log.
Hope someone out there can help me. Thanks in advance.

Is your cmake a really old version? (cmake --version). The compiler version 4.9.2 is 10 years old.
It should create the build dir if needed and it should process those if args. Maybe I can find a compatible solution if I can reproduce the environment. Is it some old Raspbian? (cat /etc/debian_version)

I'll try an install of Debian Jessie and see if we can be compatible still.

And you can just delete that block, it's only diagnostics. Maybe that was the only blocker.

rtl_433/CMakeLists.txt

Lines 103 to 107 in afb5b34

	# Enable Static analysis on GCC13.2.0+
	if("${CMAKE_C_COMPILER_ID}" STREQUAL "GNU" AND CMAKE_C_COMPILER_VERSION VERSION_GREATER_EQUAL "13.2.0")

Thank you for your support.

It now builds but fails in the linking. I've attached my log. Hope you have yet another trick in your sleeve.

OpenSSL is found but can't be properly linked. If you don't plan to use TLS (mqtts / influxs) then disable it using
mkdir build && cd build && cmake -DENABLE_OPENSSL=OFF .. && make

[zuckschwerdt]

There are now hints for building with older CMake (3.13 and 3.6) on https://triq.org/rtl_433/BUILDING.html#cmake
The compatibilty has been fixed with 7751b57

Rebased and build with your added instructions. All went without a glitch. Thank you very much.
