[Discuss-gnuradio] simple_ra and Ubuntu 16.04 LTS

[John Shields]

Hi,
   Since I moved from 14.04 LTS to 15.10 a couple of weeks ago, I have 
been experiencing segmentation faults on i965_dri (graphics rendering).

   In order to (hopefully) move away from this issue, yesterday I 
upgraded to 16.04 LTS and rebuilt GNURadio (3.7.9.2) and UHD using 
Marcus' script - only new
   issue thrown up was:

      Checking for package python-wxgtk2.8
      Failed to find package 'python-wxgtk2.8' in known package 
repositories
      SOME THINGS MAY NOT BUILD AS A RESULT

       (16.04 appears to have 3.0 version )

   I have seen this sort of diagnostic before on (Failed to find 
package 'libzmq1-dev' in known package repositories) but things seemed 
to work OK so continued.

   I can get into GRC etc.

   I decided that I should re-compile simple_ra and followed the 
instructions I usually do: cd/trunk; cmake . ; make etc.

   at the cmake level, I got the following warnings:

     GNURADIO_BLOCKS_FOUND = TRUE
     CMake Warning (dev) at 
/usr/local/lib/cmake/gnuradio/GrTest.cmake:45 (get_target_property):
     Policy CMP0026 is not set: Disallow use of the LOCATION target 
property.
     Run "cmake --help-policy CMP0026" for policy details.  Use the 
cmake_policy
     command to set the policy and suppress this warning.

     The LOCATION property should not be read from target 
"test-ra_blocks".  Use
     the target name directly with add_custom_command, or use the generator
     expression $<TARGET_FILE>, as appropriate.

     Call Stack (most recent call first):
     lib/CMakeLists.txt:71 (GR_ADD_TEST)
     This warning is for project developers.  Use -Wno-dev to suppress it.

    when I did a make, I got:

   I wonder if I have made an error some way along, but cannot imagine 
what.

   Any ideas?

          Kind Regards,

                 John
