python - "ImportError no module named gnuradio" when trying to execute ./uhd_fft -


i have followed instructions out lined here:

http://forums.nuand.com/forums/viewtopic.php?f=9&t=2804

and installed gnu radio git repo (scroll down section says "building gnuradio git". used ./build-gnuradio.sh script , took while, appeared build successfully, per instructions.

i running on ubuntu 12.04 lts.

when attempt run "./uhd_fft" function following error message: 

traceback (most recent call last):   file "./uhd_fft", line 23, in <module>     gnuradio import gr, gru importerror: no module named gnuradio

i have googled error message , of forums claim there problem pythonpath.

when 

echo $pythonpath /usr/bin/python2.7

but when check python2.7 directory not see gnuradio. guess makes sense i'm getting import error when tries import gnuradio. bigger question why?

i installed gnu radio (per instructions nuand forum) using ./build-gnuradio.sh script. should have installed.

i appreciate if python / gnu radio experts community weigh in.

there section later in instructions boldface label:

now voodoo new program installed system libraries , python paths , executable path.

those instructions lead through modifying pythonpath pick gnuradio module, among other things. if have followed instructions, have start new shell see effect, or execute .sh file hand, since profile scripts run when new shell starts or when they're run manually.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
