Trying to do a debug build

Hello everyone!

I am trying to do a debug build. I am following the instructions at
gnuradio/wiki/BuildGuide page:

[email protected]:~/src/gnuradio/build$ cmake
-DCMAKE_BUILD_TYPE=Debug

but this is what i get:

CMake Error: The source directory “/home/matt/src/gnuradio/build” does
not appear to contain CMakeLists.txt.

What am i doing wrong here?

Thanks!

You have to tell cmake where the source directory is. Looks like for
you it’s one level up, so append " …/" to your cmake command.

I accidentally did with only one dot “./”. however it is building now.
will this work?

I don’t think so. That seems a very odd response since ./ is your
current directory, which doesn’t have the source in it. I’d stop it,
clear your build directory, and try again to make sure nothing odd
happens.

oh so i stopped it, cleared the build dir and did:

[email protected]:~/src/gnuradio/build$ cmake …/
-DCMAKE_BUILD_TYPE=Debug

now i get:

CMake Error at CMakeLists.txt:22 (message):
Prevented in-tree build. This is bad practice.
– Configuring incomplete, errors occurred!

i am still missing something here.

This can also happen when you called cmake directly from the source dir
at one point. If this is the case, you will have some files in your
source dir (src/gnuradio) which shouldn’t be there. If you haven’t
touched anything, the easiest way to get rid of these is

$ git clean -xdf

If you don’t want to do that, clear out anything from the source dir
related to cmake except for the directory cmake/ and the file
CMakeLists.txt.

Hi,
the only other file in src/gnuradio is CMakeCache.txt so i deleted it.
then ran

cmake …/-DCMAKE_BUILD_TYPE=Debug

in build directory. it is building now. So is all well?

Ok, so it looks like you’ve copied the source into your build
directory or something. At least, there’s something wrong with your
directories, the location of the source code, or where you’re building
from.

Make sure that the source code is checked out into ~/src/gnuradio.
Then follow these steps:

$ cd ~/src/gnuradio
$ rm -rf build
$ mkdir build
$ cd build
$ cmake -DCMAKE_BUILD_TYPE=“Debug” …/

That’s just to make absolutely certain your build directory isn’t in
some confusing state.
