I am doubting the libtool error in this one. If you have the libtool error, it shows up well before this. You cannot complete the make.

IF you cannot complete the make, and it dies in making the mblock message block code, then you can go back to the pmt directory and in that directory do install

cd pmt
make install
cd ..

the make will now complete mblock in a few seconds and the rest of the tree will build. From there, I have no problems at all with the main branch.

I have been UNBELIEVABLY tied up since the first of the year and I have no revisited the Rondeau, Ettus, and McGwier (n4hy) OFDM code since that time. I will make it tonight and see what happens.

Tom will be here through the weekend and possible we can check into it if I discover a problem.

I have FC6 on X86_64 with swig.x86_64 1.3.31-0.fc6 installed. I presume
there's a problem with my swig-python or swig- what versions of everything
should I be using?

Replying to myself here, I heard from someone that I should do make
uninstall on the standard tree before doing make install on n4hy's tree. I
make uninstalled both just to make sure it was cleaned out, and toasted
/usr/local/lib/python2.4/site-packages/gnuradio (same for lib64) and did
make install of n4hy's - only to discover that _gnuradio_swig_python is now
missing. Another make uninstall, another rm, and reinstalled the stable
tree- which yields the same error.

Why is make install not putting _gnuradio_swig_python in place do you
suppose? Have I missed something?

Which distribution are you guys using?

I believe that the Ubuntu libtool problem is still unresolved.
I'd really appreciate it if somebody who uses ubuntu would test and
document a fix.  I suspect that it could be as easy as rolling libtool
back to libtool-1.5.22-3
