Thanks Dave, but that did not seem to work for me. Here were the
commands I ran (slightly different than recommended, but that was for
some different recipe mods that have nothing to do with this issue):
$ export CXXFLAGS="-std=c++11"
$ PREFIX=/opt/gnuradio/v3.7.12.0
$ yes | pybombs prefix init $PREFIX
$ yes | pybombs -p $PREFIX recipes add gr-recipes
git+https://github.com/gnuradio/gr-recipes.git
$ source /opt/gnuradio/v3.7.12.0/setup_env.sh
$ pybombs -vvv -p $PREFIX install gnuradio
And currently things keep erroring out at the same place while
installing UHD:

I've also tried env CXXFLAGS=-std=c++11, but it had the same issues.
That error is internal to the compiler, it is failing to perform its job
correctly. This has nothing to do with Gnu Radio, per se, or PyBombs
or any of that. This ordinarily means you compiler is broken in some
way.
HOWEVER. How much memory do you have on the system?
This issue used to happen on systems with small physical memory, because
compiling certain things requires a lot of virtual memory
on the part of the compiler.
Jason,
You can set the CXXFLAGS env variable to "-std=c++11" and any
CMake builds you run (assuming the same shell) will check the
CXXFLAGS var first. This assumes that you don't overwrite the
value of CMAKE_CXX_FLAGS. I just tried it in a terminal with
`export CXXFLAGS="-std=c++11"`, then `cmake ..`, and finally
`VERBOSE=1 make -j 1`. The verbose make command will show you if
your flags are taking or not.

I am trying to install gnuradio onto a Centos 7 box and am
having more and more issues with packages that use c++11
commands. For some of the packages, I add the line:
CMAKE_CXX_FLAGS "-std=c++11"
to the module's CMakeLists.txt file.
The issue is that that requires a fetch, the mod, and then a
rebuild. This worked OK with it was just gqrx I was doing it
for, but now I need it for other modules it appears, and so I
am trying to find a more elegant solution that covers
everything that is built via a pybombs install gnuradio
command (like gr-blocks, which I can't use this trick for).
If I understand the problem correctly, Ubuntu uses new enough
tools to realize that it needs to use the c++11 version (or
newer I assume) to build since it is needed. It seems like
even though Centos 7 has the c++11 capability, it does not
smartly trying to use it, and must be directed to for the
installs to work.
Is there something I can do at an upper level to make things
happy on an install?
