Subject: [USRP-users] Is it possible to build a uhd lib for using in
qt?
Message-ID: <[email protected]>
Content-Type: text/plain; charset="iso-8859-1"
Hi every body
I've read about creating static librarys from uhd, but this are libuhd.so file.
In addition I found out, that at the build-time a flag could be set for dynamic
librarys. But when I add the .a lib to any qt programm, I get a couple of
errors. The include-paths are all set to the uhd and boost directory (so the
only problem are unresolved references to the functions).
In the mailing list archive I found the succestion for placing the custom file
in the example directory and modify the CMakeList to build it with all other
files. But my intention is to create a simple GUI to control the radio and plot
some information, and not a terminal app.
Or is there a better way to create custom GUI applications with uhd (using also
custom fpga image)?
Best regards,
Patrick

Hi Patrick,
yes, you can link Qt applications against UHD. For example, GNU Radio
has the gr-qtgui module, and you can do wonderful things containing both
USRP connectivity through UHD and Qt GUIs.
So, probably the exact error messages would be helpful here. I don't
know what your development platform is, but with GCC, you usually don't
add an .a to a program, but point the linker to the right directory
containing the libuhd.a (-L /path/to/) and tell it to link against that
(-luhd). If you're writing your own Makefiles, or need to add
compiler/linker options somewhere and are running linux or any other
system that uses pkg-config:
pkg-config --libs uhd
will give you the right flags.
The CMakeInfo still applies ? the way linking works is totally
indifferent of whether your program has buttons or not ;)
Best regards,
Marcus

hello all
i download the image of e310,and i write it to the card and boot the E310
sucessfully
now, i wnt to uninstall the gnuradio pre-installed ,and install another
version of gnuradio
but i got the error

so i want to know how to reinstall the gnuradio of e310 or can i get a
image without gnuradio(just the operating system)
thank you

Hi Ekko,
the E310 is an embedded system, and you usually don't uninstall things
that are on the device, or build larger things to run on the device on
the device itself.
So the way we generate the E310 images is using
OpenEmbedded/Yocto/Bitbake, as explained on the manual page, to compile
all the software on a PC, and then put all that into a filesystem image.
So for the reduced image, you could just comment out the GNU Radio
layers in the meta-sdr recipe used in the build system; maybe Philip
Balister has even made such a recipe ready to run? He's our OpenEmbedded
guru and in charge of producing these images.
Regarding re-installation of GNU Radio: Why do you need that? The GNU
Radio Recipe(s) should be pretty recent. Again, feel free to modify the
recipes/layers to accomodate changes.
Best regards,
Marcus

Hi Ekko,
Philip informed me of this post:
http://www.opensdr.com/posts/building-small-gnuradio-images/
Maybe that helps.
Best regards,
Marcus
