INDIGO is the next generation of INDI, based on layered architecture and software bus.

This is the list of requirements taken into the consideration:

1. No GPL dependency to allow commercial use under application stores licenses.
2. ANSI C for portability and to allow simple wrapping into .Net, Java, GOlang, Objective-C or Swift in future
3. Layered architecture to allow direct linking of the drivers into applications and or to replace wire protocol.
4. Atomic approach to device drivers. E.g. if camera has imaging and guiding chip, driver should expose two independent simple devices instead of one complex. It is much easier and transparent for client.
5. Drivers should support hot-plug at least for USB devices. If device is connected/disconnected while driver is running, its properties should appear/disappear on the bus.
6. FITS, XISF, JPEG, TIFF, RAW, AVI and SER format supported directly by the framework.

This is already done

Framework

1. INDIGO Bus framework
2. XML & JSON protocol adapter for client and server side
3. indigo_server - server with loadable (indigo .so/.dylib and indi executables) drivers
4. indigo_server_standalone - server with built-in drivers
5. INDIGO Server for macOS wrapper (provided just as an example)
6. Integrated HTTP server for BLOB download & server control (= web based INDI control panel)

How to build INDIGO

Prerequisites

Ubuntu / Debian / Raspbian

sudo apt-get install build-essential autoconf autotools-dev libtool cmake libudev-dev libavahi-compat-libdnssd-dev libusb-1.0-0-dev libcurl4-gnutls-dev libz-dev git curl bsdmainutils bsdextrautils patchelf

It is advised to remove libraw1394-dev

sudo apt-get remove libraw1394-dev

Fedora

dnf install automake autoconf cmake libtool gcc gcc-c++ libusb-devel avahi-compat-libdns_sd-devel libudev-devel git curl curl-devel zlib-devel

It is advised to remove libraw1394-devel

dnf remove libraw1394-devel

macOS

Install XCode and download and build autoconf, automake and libtool (use tools/cltools.sh script).

Get code and build it

git clone https://github.com/indigo-astronomy/indigo.git

cd indigo

make all

build/bin/indigo_server -v indigo_ccd_simulator [other drivers]

and connect from any INDIGO/INDI client or web browser to localhost on port 7624...

No pthread_yield()

New linux distributions come with the latest glibc that does not provide pthread_yield() However libqhy.a depends on it. We do not have control over this library and it is not officially supprted by QHY any more. So if you get complaints by the linker for missing pthread_yield call please execute the folowing command in indigo_drivers/ccd_qhy/bin_externals/pthread_yield_compat/:

make patchlib

and rerun the build
