Hello All:  
this is my first time on the list. I’m running gnuradio 3.7.6.1  
with  
pybombs. I’m now trying to install OpenLTE which is dependent on  
Gnuradio  
and when it calls cmake to check for gnuradio’s packages it can’t find  
it.  
Originally, the ‘FindGnuradio.cmake’ file wasn’t in the cmake/modules  
directory, so that was an easy fix, now it runs a little further, and  
this  
is the output:

– Boost version: 1.54.0

– Found the following Boost libraries:

I usually just figure this stuff out on my own or with the help of  
coworkers, but i figured i’d give the group a try.

Any help with this would be greatly appreciated.

Thanks,

It looks like there’s some confusion in the configuration process. It  
looks  
like it’s using FindGnuradio.cmake, which will be removed in the next  
API  
version update since we are now using the GnuradioConfig.cmake method of  
doing this. This shouldn’t be a problem, but It looks like there might  
be a  
bug that’s causing this because of the install and cmake paths.

Take a look at /usr/share/cmake-2.8/Modules/FindGnuradio.cmake and go to  
the very last line and make this substitution:

-GR\_MODULE(PMT gnuradio-pmt pmt/pmt.h gnuradio-pmt)  
+GR\_MODULE(PMT gnuradio-runtime pmt/pmt.h gnuradio-pmt)

The PMT library is provided by gnuradio-runtime, so they are in the same  
package config info.

thanks Tom! That seemed to get me one step further.  
a couple of notes:

1. do you any thoughts on the next error (output included below)? looks  
like the same thing except, polarssl is now not mentioned in the  
findgnuradio.cmake file.
2. a friend mentioned to me that there is a pybombs recipe for openlte  
which i ran successfully (while feeling like a bit of a dope for not  
thinking of it first).

with that said, shouldn’t i still be able to compile the source for  
openlte  
without using its pybombs recipe? I would like to resolve the cmake  
error,  
but in the interest of not wasting your time, please understand that  
openlte DID compile through pybombs. I guess the cmake issue is just a  
bit  
bothersome, especially if i want to compile GNURadio code that is out of  
tree for pybombs.

thanks,

First, that’s now a problem with the openlte build system and nothing to  
do  
with GNU Radio.

Second, it’s not polarssl that’s the problem here. When it says it  
didn’t  
find it, it means that pkg-config couldn’t locate it, but you’ll notice  
the  
second two lines have found the libraries and headers because cmake went  
and looked for them on its own.

The real problem is the next line where it says it can’t find  
gr-osmosdr,  
which is either not installed or is installed somewhere where the  
openlte  
cmake system isn’t able to find it.

1. a friend mentioned to me that there is a pybombs recipe for openlte

Might as well stick with pybombs. It knows what it’s doing with these  
things.

Specifically, since it all gets installed into the same prefix, that’s  
helping cmake find things easier.

Tom

with that said, shouldn’t i still be able to compile the source for  
openlte

ok, Thanks. i’ll work with it some more. I’m now having issues running  
anything that’s installed using pybombs as root (a requirement of  
openlte).  
That’s an OS thing though, not gnuradio related.

thanks for the answers Tom, i appreciate the time.

Just to be fair to the openLTE folks, it builds just fine here with a  
properly installed GNU Radio.

I have had a working version of OpenLTE on a different system with a  
traditional build of GNURadio. When i got new computers at my lab i  
decided  
to build gnuradio using pyboms because it seemed like the newer more  
streamlined option.

Are you using pybombs to install Gnuradio, Ron?

I haven’t tried pybombs. I always build from source. It doesn’t seem  
like that much of a hassle to me, but I’m a long time software  
developer.

Just for the sake of the archives and marking this issue closed, i was  
finally able to get gnuradio and the openlte pybombs recipe to run, i  
had  
to:

1. give openlte sudo privileges
2. add libuhd.so.003 to a .conf file i made called  
/etc/ld.so.conf.d/randomLibs.conf
3. run sudo ldconfig.  
I’m still suspecting the manual adding of libuhd has to do with the  
isolated environment of pybombs. I’m definitely not giving up on it yet  
though.

hope this isn’t too off topic, just hoping to help some other new users  
if  
they’re branching out, plus i think the libuhd issue is one that could  
occur in other situations.

thanks,
