Hi Weo,
Sorry to hear about your trouble, and at the same time, thanks for
spelling it all out.
A couple of comments, in general. I don't mean these as any kind of a
personal attack, if anything, it just shows that we *do* have
challenges with installation.

Good choice. It's one of the two distributions I use every day.
FWIW I also use KDE.
With Mandrake 10.1, I believe that there are only *three* things that
didn't come with the distribution that you would have needed to build.
Even fewer with SuSE 9.3 Pro.
These would have been cppunit, FFTW and SDCC.

The README in gnuradio-core contains the magic required for FFTW, e.g.,
(2) FFTW 3.0 or later http://www.fftw.org
IMPORTANT!!! When building FFTW, you MUST use the --enable-single and
--enable-shared configure options. This builds the single precision
floating point version which we use. You should also use either the
--enable-3dnow or --enable-sse options if you're on an Athlon or Pentium
respectively.
FYI, I just confirmed that fftw-3.0.1.tar.gz builds perfectly out of the box.
./configure --enable-single --enable-shared --enable-sse
make
make install
Out of curiosity, where did you ever get the idea that "make
distclean" was a good idea? Stands for "distribution clean" and
generally used only by folks (possibly with special tools) while
building distributions. I only use it when generating and testing the
tarballs. I would put using "make distclean" in the "blowing your own
foot off" category ;)

Not true. Having /usr/local/bin in your PATH goes a long way.
I understand that if you're not familar with Linux or other Unix
like things, some of this may seem abritrary and capricious, but it's
really the water we swim in. Perhaps investing in a "getting started
with Linux system administration" book might help.

Also not true. I'm using whatever came with Mandrake 10.1 and
SuSE 9.3. A quick check shows that Mandrake 10.1 ships with 1.8.5 and 1.4.

Have you tried Mandrake's graphical "Software Management" tool?
It's right on the panel and looks like a red wrench. Brings up
"Mandrake Control Center", then click on "Software Management", then
"Install", search for "automake".

Yes, you do need to install boost.
Boost 1-1_31 in /usr/local works fine. Yes, I agree that if it's
installed somewhere else or a different version, it's a serious pain.
This definitely needs fixing.

Sorry to hear that.
Looks like all of this validates Lamar's point about RPMs being "the
right answer" for RPM based systems. [The challenge from the
developer's point of view is that there are so many distributions and
versions, and they potentially require different rpm specification
files, build specific fixes, etc. But hey, that's not your problem...]

I don't have much experience with Knoppix or other "live CDs".

Looks like RPM's would make your life easier.
As soon as we release the 2.6 tarballs, you may want to try building
using them. Or wait for a Mandrake 10.1 set of RPMs.
> Thank you, Weo WN6I
Thanks for all of your input. And again, sorry to hear about your
frustration. With some luck and effort I think we can address most of
your concerns.
Regarding "inscrutable command lines" --
Learning to use/program the shell is an eye opener, and an amazing
productivity tool, especially if you come from a dumbed down windows
environment. Lots of good tutorials on the web. Look for ones on
/bin/sh "The Bourne Shell", or "Bash". If you like your information
really dense, try "man bash" -- it's all in there. Avoid csh and
tcsh, they're different beasts, and the last thing you need right now
are more options to complicate your life!
