Hi, good to hear you got it working.

This can happen for a number of reasons, including having multiple applications trying to use the same camera at the same time. Do you use the camera for imaging and guiding? Do you use an INDI camera, and you have it connected in the INDI client, or in KStars/EKOS, and also in PHD2? If you continue to have problems then we would suggest you raise it with the PHD2 community (https://openphdguiding.org/getting-help/).

Hi Javier, the PHD2 installation checks the installed INDI version by looking at the header file in the include folder:

cat /usr/include/libindi/indiapi.h | grep INDI_VERSION
#define INDI_VERSION_MAJOR 2
#define INDI_VERSION_MINOR 0
#define INDI_VERSION_RELEASE 7

Do you see something else? Do you find instances of indiapi.h in other folders?

sudo find / -name indiapi.h

pijavier@raspberrypi:~/Projects/phd2/tmp $ phd2 –version
2.6.13dev4
pijavier@raspberrypi:~/Projects/phd2/tmp $

Everything went ok and the testing gave the following result:

pijavier@raspberrypi:~/Projects/phd2/tmp $ indiserver
2024-06-27T21:05:25: startup: indiserver
Usage: indiserver [options] driver [driver …]
Purpose: server for local and remote INDI drivers

Code 2.0.8-tgz. Protocol 1.7.
Options:
-l d : log driver messages to /YYYY-MM-DD.islog
-m m : kill client if gets more than this many MB behind, default 128
-d m : drop streaming blobs if client gets more than this many MB behind, default 5. 0 to disable
-u path : Path for the local connection socket (abstract), default /tmp/indiserver
-p p : alternate IP port, default 7624
-r r : maximum driver restarts on error, default 10

-v : show key events, no traffic
-vv : -v + key message content
-vvv : -vv + complete xml
driver : executable or [device]@host[:port]

As far as I understand the version is 2.0.8, then so far so good.

But when I compile PHD2 this is the result:

pijavier@raspberrypi:~/Projects/phd2/tmp $ cmake -DUSE_SYSTEM_LIBINDI=1 -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ~/Projects/phd2

pijavier@raspberrypi:~/Projects/phd2/tmp $

So surprisingly it says:
— INDI version 1.9.9 found in /usr/include/libindi, but at least version 2.0.0 is required
INDI not found. Please install INDI and try again

Why finds version 1.9.9, if after executing “indiserver” it says is version 2.0.8?

What should I do to complete PHD2 installation?

Thanks

Javier

Hi,
I ran into the same problem (indi 1.9.9 instead of 2.0.0), following your instructions to install the indi server from source, then installing phd2 from source. I suspect that installing the prerequisites per your instructions for phd2 which include “libindi-dev” is the culprit. When I recompiled/installed indi after installing the prerequisites for phd2, it worked except for the fact that I also needed to sudo apt-get install libopencv-dev before (on a freshly installed rpi5 with bookworm lite).
Cheers,
Karl

Hi David, it looks you have an older and incompatible version of libindi installed, as suggested by the error message:

INDI version 1.9.9 found in /usr/include/libindi, but at least version 2.0.0 is required

Did you install libindi from the Debian package or using our guide?

I looked at the .log file but could not make any sense of it as I have no real knowledge of how to build PHD2 and am just blindly following the instructions. FWiW if I type indiserver I get this:

davidjkreiton@raspberrypi:~/Projects/phd2/tmp $ indiserver

What do I need to do to build PHD2?
Thank you for your help.
