I found out about using condition variable [1] and implemented one to get this behavior. Thanks anyways :)

Hi all :) I am developing a simple rotator client that takes a few arguments, connects to the rotator (currently a simulator), and it should just exit the program after reaching its destination. However, if I simply use 

exit(0);
after reaching the destination the program complains
BaseClient::~BaseClient: Probability of detecting a deadlock.

I am wondering what is the clean way to exit the program after reaching certain conditions without the need of human intervention? Should I just write a `while(true)` loop and check for conditions in the `main` function? If so, I am worried about blocking the CPU. Should I be worried?

Thanks in advance,
Pedram

Thanks for your reply Jasem. I didn't find anything other than the arm64.deb [1] that Adam Robichaud [2] sent to you in the diffractionlimited forum post [3]. Is there any way we can help? Or should we just be patient and wait for a response? :(

I noticed this discussion on diffraction limited forum asking for SBIG ALUMA CCD Series Linux SDK. Are you planning on releasing an update in the INDI SBIG 3rd party repository so that ALUMA users can drive this CCD with INDI-friendly clients? It would be a huge relief to use ALUMA drived by INDI in RPi ARM64.

Reading the FindSBIG.cmake file I found out about libsbigudrv. So:

$ sudo apt-get install libsbigudrv-dev
The output:
[Warning: Spoiler!]
And voila, no problems after this. Compiled and installed 'indi-sbig' successfully.

Hi all. I am using a x86_64 system and still I can not build the SBIG CCD driver.

I took the steps on indilib website for installing SBIG CCDs , to be specific:

$ sudo add-apt-repository ppa:mutlaqja/ppa
$ sudo apt-get update
$ sudo apt-get install indi-sbig


But when I try to run the SBIG service in KStars, it crashes complaining it cannot find the libsbig.so.4 file. Log file is attached to this reply. I'll also put the contents at the end of this reply.

So then I tried installing SBIG from indi-3rdparty github repository . I tried installing only the SBIG driver, so here are the steps I took.
  1. Installed the INDI core library with git clone and cmake as instructed. Perfect success.
  2. Cloned the INDI 3rd party drivers github repository
  3. Followed the instructions for building the INDI 3rd party drivers individually like:
    $ mkdir -p ~/Projects/build/indi-sbig
    $ cd ~/Projects/build/indi-sbig
    $ cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ~/Projects/indi-3rdparty/indi-sbig
    And got the error:

    -- Found CFITSIO: /usr/lib/x86_64-linux-gnu/libcfitsio.so
    CMake Error at /home/ino/apps/indi-3rdparty/cmake_modules/FindSBIG.cmake:44 (message):
      SBIG not found.  Please install SBIG Library http://www.indilib.org
    Call Stack (most recent call first):
      CMakeLists.txt:14 (find_package)
    
    
    -- Configuring incomplete, errors occurred!
    See also "/myPath/indi-sbig/CMakeFiles/CMakeOutput.log".

    Also I put the cmake log contents at the end of the reply and in the attachments.

Actually Jasem has pointed this out in this github isuue . This worked fine for me too. I had to manually remove some indi-related left-overs from previous installations.

It looks like I had to delete previous libraries **manually**. A simple reinstall did not work for me. Maybe that is because all indi-related libraries were not removed automatically.

Hello, I am copying this from the github issue opened up with the same subject. Any help would be appreciated. Thanks in advance.

I tried the walkthrough on pip website since it is the recommended method for Ubuntu users.
This includes installing all prerequisites calling: `sudo apt-get install python-setuptools python-dev libindi-dev swig`
Then I get a _successful_ install of <strong>pyindi-client-0.2.6</strong> using _pip3_ calling: <code>sudo -H pip3 install pyindi-client</code>
But as soon as I try to import <strong>PyIndi</strong> the python instance crashes with the message: segmentation fault (core dumped)
I tried reinstalling the dependencies, but no luck.
Also, I checked the package calling: `pip3 check pyindi-client` and I got the response _No broken requirements found_
Then, after reading the stackoverflow question: [python tracing a segmentation fault](stackoverflow.com/a/2664232/6474744) I tried to get to the root of the problem using **gdb** by calling:
<code>
$ mkdir db-pyindi
$ cd db-pyindi
$ echo "import PyIndi" > import-pyindi.py
$ gdb python3
