Build on Raspberry Pi 3 B+ fails on FFmpeg

[pwierzchon]

Hi, I want to compile javacpp-presets on Raspbery Pi 3 B+ with the new Raspbian Stretch. I follow your instructions which worked perfectly for build on the previous RPi model (https://github.com/bytedeco/javacpp-presets/wiki/Build-Environments), but this time it fails on FFmpeg giving the following stack trace:

patching file configure
Hunk #1 succeeded at 5955 (offset 1 line).
gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

Any ideas how to fix that?

@vb216 What would we need to support that model?

[vb216]

@pwierzchon did it compile ok using Stretch distro on other Pi models / recently? Or has it never worked on Stretch?

I'm guessing maybe different gcc version shipped nowadays, or one in the setup instructions isn't available any more (assuming its never worked on Stretch).

Hopefully shouldn't be too tricky to resolve, will grab latest raspbian distro and give it a try locally.

[pwierzchon]

It compiled ok with Stretch distro 4-5 months ago. Now my company gave me a new Pi and asked me to set up the environment using new Stretch.

[vb216]

pull #548 should fix this

If you want it quickly, you can manually modify ./ffmpeg/cppbuild.sh to bring it in line - just needs an extra lib path added as I guess in latest Stretch they moved some things around

Thanks @vb216!

Great, FFmpeg passed.
But now I got a strange error in FlyCapture:

Installing "flycapture"
/home/pi/javacpp-presets/flycapture/cppbuild /home/pi/javacpp-presets
Please place flycapture.2.11.3.121_armhf.tar.gz in the downloads directory

Clue is in the message itself, you need to download flycapture (you have to accept some license stuff to be able to access it) and place it in ./javacpp-presets/downloads directory, then you can resume the build from that step, it'll find the flycapture source and carry on

[saudet]

Right, just skip any module you don't need. BTW, the precompiled binaries should work. Why not use those?
