Hi,

what is THAT??? Occurred with the 3.7.2 download package…

enterprise:/usr/src/gr-build # cmake …/gnuradio-3.7.2
CMake Error at CMakeLists.txt:22 (message):
Prevented in-tree build. This is bad practice.

– Configuring incomplete, errors occurred!

It looks like you tried an in-tree build, which cmake prevented you from
doing, because it’s bad practice :slight_smile:

You’ll need to clean the repo (if nothing’s changed, git clean -xdf will
do) and then rebuild outside your tree. Follow the build instructions,
and make sure you call cmake in a separate build folder.

Did you actually read what I posted?
I was calling “cmake …/gnuradio-3.7.2” while being in the directory
“/usr/src/gr-build”.

And I didn’t use git but the download package from the gnuradio website.

Yes, Stefan, I read what you posted. Did you read what I just posted?
About making sure you’re helping people help you solve your problems?
Also remember, this thread isn’t only for your benefit, but for others
with similar problems who might read this now or find it in the archives
later.

Now, the most common cause for your problem is leftover cmake files.
As I said, clean out the source dir before continuing.

And I didn’t use git but the download package from the gnuradio website.

I’m assuming you’re able to ignore my suggestion in that case and clean
the directory using other methods.

Point taken. However, I was not in-tree in that case unless I understand
the expression “in-tree” wrong. It does mean “inside the directory where
all the source files are”, doesn’t it?

rm -rf gnuradio-3.7.2
rm -rf gr-build
tar xzf gnuradio-3.7.2.tar.gz
md gr-build
cd gr-build
cmake …/gnuradio-3.7.2

=> same result

I’m totally unable to reproduce that behaviour; my wisdom ends here.

Yes, although the error message is triggered when it finds specific
files inside the tree, even if you actually call cmake from outside the
tree. So if you do an in-tree build first, then realize your error, and
try the out-of-tree build afterwards, you still see the same error.

cd gr-build
cmake …/gnuradio-3.7.2

=> same result

OK, that’s unusual and I can’t reproduce it here even by copy & pasting
the commands and doing exactly the same. You could try 3.7.2.1 (although
I couldn’t say why 3.7.2 wouldn’t work) and using other build
directories.

While you’re at it - why do you download tarballs instead of simply
taking the git route, giving you the recent version; or even trying
the pyBOMBS way, which might even install dependencies for you
(honestly, I don’t know if it works with Suse, though, or tries to
build all tools and requirements from source instead of fetching
packages where applicable).

I downloaded the file new and deleted everything and created the dirs
new again and then it worked - basically. Typical Suse-phenomenon - tons
of dependencies not found…
Luckily, I found a 3.7.3-git version on OSBS which runs fine so far.

The dependency “problem” is not confined to any one distribution, you’ll
find tons of -dev packages needed in Ubuntu/Mint, etc. and -devel
packages needed in Fedora and openSUSE.
These are files that are not installed by default even when you specify
various development options at install time, e.g the following had to be
done on Ubuntu for building ghpsdr3-alex and then some others will be
discovered after they are installed and yet others when building other
applications.
" apt-get install libfftw3-dev libasound2-dev libportaudio2
portaudio19-dev libncurses5-dev libwxbase2.8-0 libwxgtk2.8-0
python-wxgtk2.8 python-wxversion libusb-dev libusb-1.0-dev
python2.7-dev"

I just wanted to get it to run first. I’m not familiar with GnuRadio yet
ad very often, if you download from GIT, you get some unstable stuff, so
unless I know a project, I tend to stick to some release-files.
