-----------------------------------------
[~Danreyn22] [~willie-engelbrecht]
The proper workaround with CMake is to add
{code:java}
-DCMAKE_EXE_LINKER_FLAGS="-latomic"
{code}
to your CMake command. This will add -latomic to the executables' link
commands, where it is required.
Using this fix, minifi master builds for me on a Raspberry Pi 4 with Raspbian
Bullseye, except for StringUtilsTests, which fails to build because char is
unsigned. You can work that around by disabling tests or by patching that file.
The proper fix for this is to detect when libatomic needs to be linked. I am
working on a PR that does that (and also fixes StringUtilsTest).
