CFTSIO will be good for Ubuntu 15.10? I'm currently using a virtual machine. anyway, even in Ekos returns an analogue problem at the same step. :unsure: I'll reply as soon I'll try to install CFTSIO :)

Thanks for all!

My current OS is Ubuntu 15.10 (64 bit).

P.S. Check these packages on your Ekos virtual machine:

With your last suggestion it worked! :) thank you so much! just a thing... the following step is not very clear for me (sorry, I'm new to this kind of things :S )

6. install ws4py:
sudo mkdir /opt/ws4py
sudo chown user:user /opt/ws4py # !!! you must change user on your system login!

at the end of the 5. step, I'm currently in the libindipython dir. Shall I have to change the dir or follow the step as I read them? and I don't understand # !!! you must change user on your system login! ... Sorry again :dry:

I got these errors when compiling in RPi3. How to enable c99 in cmake?

I solved the problem by

nano /home/pi/INDI/libindipython/CMakeCache.txt
//Flags used by the compiler during all build types.
CMAKE_C_FLAGS:STRING=-std=c99

But now I get this error
[100%] Building C object CMakeFiles/_PyIndiServer.dir/indiserverpythonPYTHON_wrap.c.o
Linking C shared module _PyIndiServer.so
/usr/bin/ld: cannot find -lindiserver
collect2: error: ld returned 1 exit status

make[1]: *** [CMakeFiles/_PyIndiServer.dir/all] Error 2

make: *** [all] Error 2

and appying cmake to libindiserver return this:

Hi,
I recently have made a try to write an indiserver in Python so I created a libindiserver library directly from the indiserver.c source file. But you don't have this library installed (it lies in the swig-indi-python directory and you should install it by hand before). You could comment the two last lines of the CMakeList.txt file to avoid the build of PyIndiServer wrapping and get rid of this error.
Now, I've been asked to make a Python installer for the client part of the wrapping, so I did start to write a distutils/setuptools Python package for pyindi-client. So you probably may now refer to it if you want only the client part of the wrapping. It lies here , you may directly download a release , unpack it and run
python setup.py install
to run all the swig/compile/install steps. I did not test it heavily, but plan to put it in the Python package index .

Jean-Luc.

PS: Actually you built the libindiserver library, but the CMakeLists.txt file in the libindiserver directory should be too old, you may try to replace FindINDI.cmake with the last one.

Yes please, put it on pypi.
I have noticed that you have written a bridge indi-stellarium. Just what I need!

I've put it on TestPypi, it still needs some little corrections. You may try with
pip install -i https://testpypi.python.org/pypi pyindi-client
Beware that pyindi-stellarium is just a sample script not heavily tested.
