Re: GNU Radio 3.8 and Centos 7: Is it possible?

[Vasil Velichkov]

Hi Andrew,

Take a look at centos-7.6.Dockerfile[1] that is used by the gnuradio's 
buildbots[2]. Builds from the master branch currently fail because of some 
recently merged changes but I just tested build of maint-3.8 branch 
successfully. 

Most of the dependencies are installed from the CentOS and EPEL[3] repositories 
but some are installed by rebuilding source RPMs, from source release tarballs 
or using pip3. The python version is 3.6 and is installed from the base CentOS 
repository (python36-devel package)
