Try to improve E100's performance at high sample rate

Ziyang -

Are you using any of our official e1xx images? I noticed that you are
manually typing in arguments for the e1xx; UHD and GNURadio are both
distributed with CMake Toolchain files for use on the E1xx devices.
Additionally, our official images come with a script that will
automatically build GNU Radio with a bunch of extra useful flags that
get
around some of the stranger package-location errors.

Regardless, you can manually check what pkg-config finds with:

$ sudo pkg-config --list-all | grep orc

Our official e1xx images come with the orc pkg-config file installed at:

/usr/lib/pkgconfig/orc-0.4.pc

Cheers,
Ben

Also, I’ll note that in our official images, orc is installed from
source,
rather than from opkg. You can find the source tarball for this install
in
~root/src/

If you choose to try this, make sure you first completely remove orc
with
opkg first.

Lastly, unless there is a really good reason to not use our official
images, I highly suggest using them. It is much easier for us to support
you if you are using a system we are familiar with.

Cheers,
Ben

Could you tell me what might be the problem? Thanks.
Add -DENABLE_ORC=ON to the cmake command line.

Thanks, Philip. But the problem remains after -DENABLE_ORC=on is added.

– Did not find liborc and orcc, disabling orc support…
– Using install prefix: /usr/local
– Could NOT find Doxygen (missing: DOXYGEN_EXECUTABLE)

However, if I check orc manually with “opkg list-installed | grep orc”,
it shows:

liborc-0.4-0 - 0.4.16-r1.0.9
liborc-test-0.4-0 - 0.4.16-r1.0.9
orc - 0.4.16-r1.0.9

And if I run a search for orc under /usr , these related files are
found:

./lib/liborc-0.4.so.0
./lib/liborc-test-0.4.so.0.16.0
./lib/liborc-test-0.4.so.0
./lib/liborc-0.4.so.0.16.0
./bin/orc-bugreport
./bin/orcc

So I guess it’s because the installation of orc is not complete. I wrote
a orc-0.4.pc, something like this:

prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include/orc-0.4
toolsdir=${exec_prefix}/bin

Name: orc-0.4
Description: Oil Runtime Complier
Version: 0.4.16
Libs: -L${libdir} -lorc-0.4
Libs.private: -L/usr/lib
Cflags: -I${includedir}

orcc=${toolsdir}/orcc

and put it in /usr/lib/pkgconfig, copy orc.h to
/usr/include/orc-4.0/orc/ . Now ORC_INCLUDE_DIR can be found by
FindORC.cmake, but ORC_LIBRARY, liborc and orcc are still missing. Is
there any way to fix this or do I need a fresh rebuild of orc? Thanks.

Terry
