How to compile v4l4j for hard-float ABI ARM

[Melan Nimesh]

Hi All,

I am trying to build v4l4j on my raspberry pi which is ruining on archlinux-hf and I am getting following error, how can I get rid of this error? 

gcc v4l2-input.o v4l1-input.o libvideo.o pwc-probe.o gspca-probe.o qc-probe.o fps-param-probe.o v4l1-query.o v4l2-query.o v4l1-tuner.o v4l2-tuner.o palettes.o libv4lconvert.a pixfc-sse/libpixfc-sse-armv7.a -Wl,-soname,libvideo.so.0 \

  -lm -lrt -shared -ljpeg -o libvideo.so.0

Hi Melan,

how do you compile v4l4j (which command do you use) ?

Hi Gilles,

I used "ant all" command in v4l4j root directory, I got an error (not remember exactly, from "libvideo" directory make file ), then I moved to directory and I used "make" command. 

Thanks,

Melan

Have you tried the instructions on this page:
https://code.google.com/p/v4l4j/wiki/GettingStartedOnRPi

Hi Gilles,

Yes, I followed instructions on GettingStartedOnRPi (I manually installed java, ant and libjpeg8-dev since apt-get not available in archlinux ), but I tried to build v4l4j-0.9.0 (since I have local modifications ), after checking out v4l4j-trunk I realized that pixfc-sse directory much different from 0.9.0. I will try to build trunk.

Thanks for the help

Melan

v4l4j 0.9.0 doesnt include support for RPI, but trunk does. Let me know if trunk doesnt build.

Hi,

I was able to build trunk without any issue on RPi. Thank for the help
