Seems not supports Raspberry PI.

same problem here, couldn't fix it with that comment thread

The required package is linux-headers-uname -r
I am not sure what the correct way to get this on a Pi is. Someone once mentioned this link
https://www.niksula.hut.fi/~mhiienka/Rpi/linux-headers-rpi/

[RanKey1496]

is this solved?

I got the linux header issue resolved on a pi...

From
sudo apt install raspberrypi-kernel-headers

Rest of the instructions worked well!

However... the binary packages pre-compiled on the Linux install instructions are for x64_86 ... not arm. So, dev mentioned you have to compile this git on the Pi. I haven't had time to play around with that...

I managed to install droidcam on Raspberry Pi 4B. Here is the list of steps:

1. For testing purpose, install droidcam on a phone. After you enter IP number that is shown in app into the browser's address bar, you should see image from your camera.

2. In order to use droidcam, you need to install libjpeg-turbo.
   Download it from this link and extract.
   Unfortunately, I guess it is required to compile it from source by oneself on Pi. BUILDING.md (Build Procedure > Un*x) is helpful.
   Execute these commands:

cd {build_directory}
cmake -G"Unix Makefiles" {source_directory}
make

where {build_directory} is /opt/libjpeg-turbo/lib32 (if doesn't exist, create these empty directories) and {source_directory} is path to directory which you extracted libjpeg-turbo to.

3. Now we can install droidcam, according to instructions on GitHub and this site (still we need to compile from sources, due to different architecture).

• download droidcam from GitHub
• install linux-headers by executing sudo apt install raspberrypi-kernel-headers
• install required dependencies (warning: gtk is huge library used to GUI, i don't know if there is some way to omit installing this 2 GB):

gtk+-3.0
libavutil-dev
libswscale-dev
libasound2-dev
libspeex-dev
libusbmuxd-dev
libplist-dev

• go to droidcam source directory
• make
• ./install
• run ./droidcam-cli <ip> <port>, instead of <ip> and <port> type data shown on your phone

If everything went well, you should be able to take a photo: fswebcam image.jpg

Feel free to add improvements and updates to this answer.

Thanks!
You can omit gtk+ and just run make droidcam-cli to skip the GUI build.

Is it possible to use the package libjpeg-turbo-progs in Raspberry Pi instead of building libjpeg-turbo from source, which @kichel98 did? That package installs in /usr/bin instead of /opt/libjpeg-turbo/bin. Also, it does not have the .h files, unlike the libjpeg-turbo package from sourceforge.

I was trying your "Howto" but always running in to this issue. Am i missing something??

pi@octopi:~/droidcam/linux $ uname -a
Linux octopi 5.4.51-v7+ #1333 SMP Mon Aug 10 16:45:19 BST 2020 armv7l GNU/Linux

[aramg]

Is libjpeg-turbo in /opt/libjpeg-turbo/lib32?
Whats the output of find /opt/libjpeg-turbo/lib32

Hey, thats the output of libjpeg-turbo/lib32

There is a supported to be an 'include' directory there (part of the libjpeg-turbo tar file).
Your screenshot doesn't show all errors, but it seems to be missing the include files

Thanks for your replay. I start from zerro. Buster 32bit on a Raspberry. Then step by step kichel98 howto. But still getting issue. Inside the "libjpeg-turbo tar file" i can´t find any 'include'
Here is what i get.

And this is the last issue. Seems you are right with the include directory. But where do i get it from?

Best
