Does anyone have experience with this? I am having trouble figuring out if it
is not working, or if I am not doing something right.
The config.yml looks like this when fresh:
!!omap
- categories:
hardware:
forcebuild: true
common:
forcebuild: true
- packages:
gnuradio:
forcebuild: true
gqrx:
forcebuild: true
I then added the line:
- config:
env:
export CXXFLAGS:STRING="-std=c++11"
to the end of it. I don't think that that is the right way to do it, but
CXXFLAGS="-std=c++11" didn't work either (no "export" or ":STRING").
Also tried just straight:
- env
CXXFLAGS: "-std=c++11"
Any ideas?

You might be able to set CXXFLAGS with the `--env` flag

I would suspect that PyBombs doesn't care about your env variables. That or
it overwrites the CMAKE_CXX_FLAGS at some point. I have no idea how PyBombs
builds the CMake projects. If it's not calling the `cmake` command directly,
then it likely will not pick up the env variable.

Run dmesg and look for messages from the OOM killer (Out of Memory)
