Installation errors

[pranali3215]

While executing the pip command I get the following error:

OSError: /home/abc/libfreenect2/include/libfreenect2/config.h: is not found

This is because the file is named config.h.in and not config.h
Even if I change the filename, during installation it is not able to find the lib folder.
This is because the lib folder is inside the build folder.

Is there something I am missing for doing this installation ?

Did you follow the installation guide? http://r9y9.github.io/pylibfreenect2/installation.html#building-pylibfreenect2

[pranali3215]

Yes!
My Protonect works and my LIBFREENECT2_INSTALL_PREFIX points to the correct location.

[r9y9]

umm

This is because the file is named config.h.in and not config.h

I think config.h.in is compiled into config.h during compilation of libfreenect2. So If you successfully built libfreenect2, you will have the config.h in your build tree.

[pranali3215]

After compilation, a new folder freenect2 got created which has the config.h file.
That folder has the include and lib folders. However, the libfreenect2 folder is as it is.

[r9y9]

You have to point out the directory freenect2, not libfreenect2.

Maybe

export LIBFREENECT2_INSTALL_PREFIX=~/freenect2

OSError: /usr/local/include/libfreenect2/config.h: is not found

Same error :(

[r9y9]

After compilation, a new folder freenect2 got created which has the config.h file.

Please point to the directory that config.h exists before installation.

[pranali3215]

There is no config.h before installation. As I said, its config.h.in.
Only after installation does it become config.h

Please make sure that:

You have installed libfreenect2 correctly and confirm that Protonect works.

Following the step, you will have libfreenect2 installed, i.e. you should have config.h before pylibfreenect2 installation. pylibfreenect2 is not libfreenect2.

[pranali3215]

As I said before, the config.h file is in a folder named freenect2 which is in /usr/local.
When I try to install the pylibfreenect2, it is not able to find the config.h file even though the correct location is given.

I am not confusing pylibfreenect2 with libfreenect2 as I do not have the pylibfreeect2 folder on my system. Hence, no confusion.

[r9y9]

Could you please tell me the full path of the config.h you have? You mean /usr/local/include/freenect2/config.h?

[pranali3215]

/usr/local/freenect2/include/libfreenect2/config.h

[r9y9]

Can you try the following?

export LIBFREENECT2_INSTALL_PREFIX=/usr/local/freenect2

[pranali3215]

OSError: /usr/local/include/libfreenect2/config.h: is not found

:(

[pranali3215]

$ echo $LD_LIBRARY_PATH

/usr/local/freenect2/lib

$ echo $LIBFREENECT2_INSTALL_PREFIX

/usr/local/freenect2

Output: OSError: /usr/local/include/libfreenect2/config.h: is not found

[r9y9]

LIBFREENECT2_INSTALL_PREFIX=/usr/local/freenect2 pip install pylibfreenect2

Doesn't it also work?

[pranali3215]

Hey,
So I cloned the repository and made following changes in the setup.py file:

libfreenect2_install_prefix = os.environ.get( "LIBFREENECT2_INSTALL_PREFIX", "/usr/local/")
to
libfreenect2_install_prefix = os.environ.get("LIBFREENECT2_INSTALL_PREFIX", "/usr/local/freenect2/")

After these changes, the setup.py works and the multiframe_listener.py is also working.

What I have understood is that it is not recognising LIBFREENECT2_INSTALL_PREFIX and hence it is taking the default, which is /usr/local/.
Thus the error that was coming was /usr/local/include as the default path did not have /usr/local/freenect2 in its path.

[r9y9]

Yes, that change should work. LIBFREENECT2_INSTALL_PREFIX=/usr/local/freenect2 pip install pylibfreenect2 should also work as well though. I guess environmental variable LIBFREENECT2_INSTALL_PREFIX isn't propagated during installation time.

[pranali3215]

I guess so.
Thank you for your help and patience !!!
I appreciated your prompt answers.
