Cross compiling to arm linux platform : Segmentation fault (core dumped)

Open kingzcheung opened this issue 3 years ago • 6 comments

I am doing cross compiling to arm linux platform. I don't need these modules like viz, sfm,freetype etc. But now I have to add these so libraries to compile.

My dependencies:

[dependencies]
opencv = {version="0.63", default-features = false, features = [ "imgcodecs","videoio","highgui"]}

Can you check if file /usr/lib/ld.so.1 actually exists in the target system?

I have recently added a sample dockerfile that sets up the crosscompiling container to Raspberry Pi, this might be of use to you too: https://github.com/twistedfall/opencv-rust/blob/master/tools/rpi-xcompile.Dockerfile and the corresponding readme section: https://github.com/twistedfall/opencv-rust#crosscompilation
