[yocto] Yocto Eclipse Plugin - Python 'undefined symbol'

[Zhang, Jessica]

Jack,

I just tried with latest poky master built out toolchain and remote debug with latest Eclipse plug-in has no problem.  My host is 32bit Ubuntu, but I don't think that makes any difference.  So how up to date is your poky meta data, mine is as of this afternoon  that contains 2 bug fixes that relevant to meta-toolchain build.  Also, seems you're using the build system derived toolchain?  If so, I can give that a try...

Thanks,
Jessica

A cheeky ldd of the binary file gives me:

linux-vdso.so.1 =>  (0x00007fff68dff000)
     libreadline.so.6 =>
/home/jack/yocto/poky-git/beagleInitial/tmp/sysroots/x86_64-linux/usr/bin/armv5te-poky-linux-gnueabi/../../../usr/lib/libreadline.so.6
(0x00007fb5cf3af000)
     libncursesw.so.5 => /lib/libncursesw.so.5 (0x00007fb5cf152000)
     libz.so.1 =>
/home/jack/yocto/poky-git/beagleInitial/tmp/sysroots/x86_64-linux/usr/bin/armv5te-poky-linux-gnueabi/../../../usr/lib/libz.so.1
(0x00007fb5cef3b000)
     libm.so.6 => /lib/libm.so.6 (0x00007fb5cec47000)

     libutil.so.1 => /lib/libutil.so.1 (0x00007fb5ce623000)
     libpython2.7.so.1.0 =>
/home/jack/yocto/poky-git/beagleInitial/tmp/sysroots/x86_64-linux/usr/bin/armv5te-poky-linux-gnueabi/../../../usr/lib/libpython2.7.so.1.0
(0x00007fb5ce248000)
     libexpat.so.1 =>
/home/jack/yocto/poky-git/beagleInitial/tmp/sysroots/x86_64-linux/usr/bin/armv5te-poky-linux-gnueabi/../../../usr/lib/libexpat.so.1
(0x00007fb5ce01e000)
     libc.so.6 => /lib/libc.so.6 (0x00007fb5cdc7b000)
     /lib/ld-linux-x86-64.so.2 (0x00007fb5cf5f1000)

Which seems to indicate that it is using the bitbake built python?
