Description brian avery 2016-09-03 00:27:47 UTC 
If you point the Eclipse plugin at the eSDK and as the standalone pre-built toolchain, there are issues because the eSDK is missing a bunch of applications from the sysroots/<host>-pokysdk-linux/usr/bin directory.

things like runqemu-extract-image - this is needed to make the pseudo happy filesystem so eclipse can launch qemu.

also missing runqemu itself. 

Basically the std sdk has a large set of tools in the sysroot/<host> dir that we are missing from the eSDK and eclipse needs a subset of these.

I've prepared a patch for this, am currently waiting for feedback from Brian on it.
Comment 2 brian avery 2016-10-05 22:27:48 UTC 
So, it's very close!  But it doesn't work yet.

It needs to have /opt/poky/esdk-22/tmp/sysroots/x86_64-linux/usr/bin/unfsd

note that its in sysroots/x86_64-linux/ not sysroots/x86_64-pokysdk-linux/

This is because eclipse runs qemu using user mode nfs to mount it's root filesystem.

If I copy the unfsd binary in, it works.

Patch sent for review - has been tested by Brian.
Comment 5 Humberto Ibarra 2016-12-01 21:18:37 UTC 
Verified that eSDK can be used as toolchain now for eclipse. Everything works as expected.
