问题 I am attempting to build the REDHAWK CF from source on a Fedora24 machine. I've hit a few barriers, and am hoping folks can provide guidance on the following two issues: 1) I cloned the RedhawkSDR/redhawk repository, and am attempting to build the CF in redhawk.git/redhawk/core/src . F24 ships with GCC6, and based on the listed supported platforms (RHEL / CentOS 6-series), I'm guessing this is a bit ahead of what the upstream is testing against. At the time of my clone, core was at cfea23b

问题 I'm using Redhawk 1.10.0 on a CentOS 6.5 machine 64 bit and USRP b100 with UHD driver 3.7.2. The USRP b100 is recognized correctly by the system. It is a USB device. I downloaded the latest version of UHD_USRP Device ver. 3.0 for REDHAWK and I created a Node including a GPP and a UHD_USRP devices. The Node is started without any problem but when I run a simple waveform to read data from the USRP as a RX_DIGITIZER I got the following error: Failed to create application: usrp_test_248_173059195

问题 I'm currently trying to build REDHAWK Explorer extensions with the source on github; however, when I try to run the Maven scripts on things, I get a missing repository error: Caused by: org.eclipse.equinox.p2.core.ProvisionException: No repository found at http://download.redhawksdr.org/nxm-rcp/releases/1.0. I see it is a repository hosted on redhawksdr.org; is this something that should be up and isn't? I know nxm point to a http://nextmidas.techma.com/; is this an internal plugin that was

问题 When stepping through debugging in the REDHAWK IDE, the line marker sometimes doesn't seem to follow proper program flow and not all variables don't seem to be updating appropriately. I am running in the chalkboard with multiple components. I start debugging by opening the component's .spd.xml file and clicking on the "debug as" hyperlink on the overview tab. This adds the component to the chalkboard with the others. The debugger hits my breakpoint after I start all of the components. Has

问题 I can't get debugging to work. I'm using the 2.1.0 version of REDHAWK and I'm trying to create custom components. I can get release version to run and to work. Here's what I do, I have created a very basic custom component that takes input, multiplies it by two and pushes it to the output stream, super simple. Now I try to run this component in debug mode in sandbox, instant crash. The only this I can see is the last entry of the callstack, which is boost::shared_ptr<rh_logger::Logger>:

问题 I'm very new to RedHawk and I have the following scenario: I have three component A B and C, B and C both have a property skill, which is one keyword describing what B or C's capability. The flow is: A starts and queries B.skill and C.skill so A knows what B and C can do. Then when A encounters a task that fits in B's or C's skill set, A will start up that specific component to do the task. My question is: how does component A access a property of B? I looked up online and found some simple

问题 I made a short .m file function myOutput = multiplyByConstant(myInput, myConstant=1) myOutput = myInput * myConstant; And then used the provided createOctaveComponent command to make it into a .. thing I go into the generated folder and try to run build.sh, but the build won't work. multiplyByConstant_base.cpp:69:22: error: 'do_octave_atexit' was not declared at this scope. I tried running grep over all the .h files I though that would matter, but the method was not exported anywhere. I found

问题 I'm running REDHAWK 1.10 on a CentOS6.5 VM. I have the connection set to bridged and can locate the USRP by its IP address using: uhd_find_devices --args="addr= <ip address>" I have a usrp2 with serial E5R1AS2UP Here are the steps I take: $ sudo $OSSIEHOME/bin/cleanomni $ nodeBooter -D -debug 5 $ nodeBooter -d <location to USRP_UHD node>.xml -debug 5 I have also run these commands as requested by the USRP: sudo sysctl -w net.core.rmem_max=50000000 sudo sysctl -w net.core.wmem_max=1048576
