Hi,  
I’m trying to build gnuradio with uhd on my system with Ubuntu 10.4.  
When building master branch everything seems ok, but I have some  
problems building the next branch of gnuradio. In gr-msdd6000/src/ there  
is an error where the compiler complains on “./python/msdd.cc: No such  
file or directory”.

I tested to revert to the latest revision that passed the build-test at  
hudson (31bbbec88b19230eb37b197d7623c3671e57837e) but then I got a  
version mismatch with the latest uhd master branch.

I also tried to go back 1,2,…,5 commits of the next branch of the  
gnuradio code, but I got the same problem and didn’t go any further on  
this reverse path. Instead I tried to fix the problem and replaced  
“python/msdd” with “python/msdd\_rs” (which exist) in the  
Makefile.swig.gen file. This seemed to fix this problem, but only gave  
me another one in gr-atsc/src which wasn’t that quick-fixable.

Have anyone else had any problems building the next branch with uhd? (I  
have myself built this branch successfully several times before, but  
doesn’t seem to have any luck on the latest revisions.)

Best regards,  
Ulrika

Also look at the “Dealing with old build problems” here:

Doh! 🙂

I didn’t think I had an old build on that location, but I did. It was  
stupid of me not to try the standard solutions before, but “make  
distclean” did the trick and everything works fine now. Thanks a lot for  
the quick reply!

Best regards,
