Hi folks,

I am trying to build on CentOS 6.5.

I cloned the repos, and then issued cd pybombs; ./pybombs install  
hackrf and it eventually failed with:

* * *

Current step: (hackrf :: configure)  
configure  
(’ \n CC=gcc CXX=g++ cmake … -DCMAKE\_BUILD\_TYPE=Debug  
-DCMAKE\_INSTALL\_PREFIX=/home/rsharpe/dev/target \n’, ’ \n CC=$cc  
CXX=$cxx cmake … -DCMAKE\_BUILD\_TYPE=$cmakebuildtype  
-DCMAKE\_INSTALL\_PREFIX=$prefix $config\_opt\n’)  
(’ \n CC=gcc CXX=g++ cmake … -DCMAKE\_BUILD\_TYPE=Debug  
-DCMAKE\_INSTALL\_PREFIX=/home/rsharpe/dev/target \n’, ’ \n CC=gcc  
CXX=g++ cmake … -DCMAKE\_BUILD\_TYPE=Debug  
-DCMAKE\_INSTALL\_PREFIX=/home/rsharpe/dev/target \n’)  
bash exec (/home/rsharpe/dev/pybombs/src/hackrf/host/build)::  
CC=gcc CXX=g++ cmake … -DCMAKE\_BUILD\_TYPE=Debug  
-DCMAKE\_INSTALL\_PREFIX=/home/rsharpe/dev/target

The problem was obvious once I checked in  
src/hackrf/host/build/CMakeFiles/CMakeError.log:

cc1: error: unrecognized command line option “-std=gnu90”

gcc version is 4.4-.7-4.el6 which does not support that command-line  
option.

Is there any way to switch it off?

Found a way to fix the problem. I changed “-std=c90” to “-std=c99” in  
two CMakeList.txt files and reran ./pybombs install hackrf and all  
worked. However, I am not sure if there is any difference between  
-std=c90 vs -std=c99 that will affect the generated code. Indeed, it  
is even possible that -std=c89 would work, but I did not try that.

That suggests that for greater portability the hackrf CMakeList.txt  
files should change that.
