I think there is another thread which describes how to use OpenCV also on uclibc (python bindings won't work).
However, eglibc might be generally a good choice if you want to go for OpenCV.
You could build an image from devkit-daisy-multilibc on meta-intel-iot-devkit - Intel IoT Developer Kit metadata which comes with OpenCV pre-installed and supports Arduino uclibc sketches.
If opencv failed for this Alex images it means that it's uclibc image?
Yes, all my ones are uClibc-based, I've added a note to README files about that.
You can check the image's libc implementation by running the below command and looking for the output listed.
root@quark:~# opkg list-installed|grep uclibc
uclibc - 0.9.33+git0+946799cd0ce0c6c803c9cb173a84f4d607bde350-r8.4
uclibc-dbg - 0.9.33+git0+946799cd0ce0c6c803c9cb173a84f4d607bde350-r8.4
uclibc-dev - 0.9.33+git0+946799cd0ce0c6c803c9cb173a84f4d607bde350-r8.4
Right now, AFAIK, Python bindings indeed don't work on the uClibc image, just like already mentioned by mhahn. One can still use C++, it works fine.
Could someone put in the Internet eglibc image for the Intel Galileo firmware 1.0.0?
And I am disturbed with the sentence "Note that supplied Arduino IDE cross compiles sketches with uClibc and they will not work with eglibc." from this post. LAN is not working in the initial stage (no default ip) and if sketches are not working too, does that mean that I can't connect to the board without serial cable (if I am succeed with eglibc image)?
DHCP client is working. So just connect galileo to router with DHCP or run DHCP server on own machine, and it's okey without serial cable.
