vcos.h missing?

[GreggsNBacon]

got a fresh install of raspbian running and I keep on encountering this issue :(

it seems that vcos.h doesn't exist or something like that. I tried to install Raspbian via NOOBS. Is that the wrong approach?

[jacksonliam]

Hmm I've not seen this, the file should be in the image. Looks like a potential bug with the pi image rather than mjpg-streamer, but could be a cmake thing.

Are you compiling on an actual pi?

Does vcos.h exist?

I also encountered this problem and found a workaround.

• Raspberry Pi ZeroW
• Raspbian Gnu/Linux 11

I found that there is no /opt/vc folder so plugins/input_raspicam/CMakeLists.txt judges HAS_RASPI OFF. but i have vcos.h at /usr/include/interface/vcos/vcos.h.

so I edited the CMakeList.txt as:

and got input_raspicam.so successfully.

I'm not sure this method is reasonable, it works on my rpi.
