hey Marcus,  
Sorry,actually that was my first message, and there is some problem,  
hence  
i am not able reply through mail archive  
These are the 2 previous links :  
[http://permalink.gmane.org/gmane.comp.gnu.radio.general/55815](http://permalink.gmane.org/gmane.comp.gnu.radio.general/55815)  
[http://permalink.gmane.org/gmane.comp.gnu.radio.general/55819](http://permalink.gmane.org/gmane.comp.gnu.radio.general/55819)

So, I am working on Ubuntu 14.10, initially i installed GNU radio  
directly  
through “apt-get” command, at that time i was getting Gnu radio\_runtime  
package error. In order to rectify the error, i downloaded zip file from  
Github website “[GitHub - gnuradio/gnuradio: GNU Radio – the Free and Open Software Radio Ecosystem](https://github.com/gnuradio/gnuradio)”  
and build all the dependencies using cmake and make command…  
i am not getting how to rectify this,  
i know you may had read this message, but once again i am sending this  
for  
rectification  
also i want to ask 2 questions.

1. installing from source means that zip file downloaded from Github  
website mentioned earlier…?
2. and whether this problem will solve my previous problem of “No module  
named howto\_swig”…\>?  
any help will be appreciated,  
Thanks in advance,  
Abhishek.

Hi Abhishek,

please regard both my answers as being independent from each other. Of  
course, you first need to fix your GNU Radio installation, and then you  
can start writing your own module.

1. Using the source code from github, you did a source build, and please  
do that again after making sure you have uninstalled all installed  
versions of GNU radio.
2. Not following the guides that still depend on the “howto” module will  
make that problem disappear, of course.

Best regards,  
Marcus
