I try to compile distribution 2011R1-RC1 with v4luvc support, but i got the compile error below. How can i solve it? I use tool chain 2011.
Yes there is some problem here, to use UVC and work around this issue you can use 2010R1 toolchain to compile the 2011 release.
I got pngview error when i change to tool chain2010, May i disable the pngview in config?
Yes, it's not needed for you uvc demo.
Please don’t build the whole 2011R1 uClinux-dist and kernel by 2010R1 toolchain.
You should build the uvc utility individually by 2010R1 toolchain to work around the compile error.
we support make only to build a single application, for example, in your case you run "make user/blkfin-apps/uvc-video_only" under the distribution, make sure to make clean under the application before doing this. For switching amoung multiple versions of toolchains, you can use link like "ln -sf uClinux.2011R1 uClinux" or "ln -sf uClinux.2010R1uClinux"
