Looking for help -- I've tried to follow a number of suggestions and have emerged raspberrypi-userland a number of times, but raspistill and raspivid still returns error:

Code:
$ raspistill -o image.jpg
raspistill: symbol lookup error: /opt/vc/lib/libGLESv2.so: undefined symbol: client_tls


Is this maybe a toolchain issue? The same hardware works fine with a rasbian image, though I notice the github userland (https://github.com/raspberrypi/userland) expects to compile with arm-linux-gnueabihf-gcc, and the closest reference to my problem (http://www.raspberrypi.org/forums/viewtopic.php?f=54&t=50037) refers to gcc/armv6j-hardfloat-linux-gnueabi/4.6.3 -- whereas I'm on gcc-4.7.3 and glibc-2.17

here's some addtional maybe-relevant background:
Code:
# uname -a
Linux Raspberry06 3.12.17-raspberrypi+ #2 PREEMPT Sat Apr 26 09:00:40 EDT 2014 armv6l BCM2708 GNU/Linux

# gcc-config -l
 [1] armv6j-hardfloat-linux-gnueabi-4.7.3 *

binutils-config -l
 [1] armv6j-hardfloat-linux-gnueabi-2.23.2 *

# emerge -pv glibc
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild   R    ] sys-libs/glibc-2.17:2.2  USE="-debug -gd (-hardened) (-multilib) -nscd -profile (-selinux) -suid -systemtap -vanilla" 0 kB

brendlefly62 ... try with:

Code:
% LD_LIBRARY_PATH=/opt/vc/lib raspistill -o image.jpg

Well, looks like an ldpath issue, but I don't have a raspberry_pi so I can't look and see ...

Many thanks, khayyam. Like that, raspistill also returns errors, but it does actually capture an image! :o
Code:
# LD_LIBRARY_PATH=/opt/vc/lib raspistill -o image.jpg
mmal: mmal_vc_port_parameter_set: failed to set port parameter 64:0:ENOSYS
mmal: Function not implemented
mmal: mmal_vc_port_parameter_set: failed to set port parameter 64:0:ENOSYS
mmal: Out of memory
mmal: Unable to set shutter speed

raspivid returns the similar errors, but captures no video: :?
Code:
# raspivid -fps 10 -w 640 -h 360 -vf -hf -t 10 -o video.h264mmal: mmal_vc_port_parameter_set: failed to set port parameter 64:0:ENOSYS
mmal: Function not implemented
mmal: mmal_vc_port_parameter_set: failed to set port parameter 48:2:ENOSYS
mmal: failed to set INLINE HEADER FLAG parameters

Are there perhaps some things I should be dong to set up the environment differently?

brendlefly62 ... you mean as far as the ldpath is concerned or these applications not behaving? As far as the former goes you could add the path to /etc/ld.so.conf.d/06-raspberrypi-userland.conf and run 'ldconfig' ... though looking at the ebuild the author (chithanh) is looking to have everything under /opt/vc moved to / (which would certainly resolve the ldpath issue).
