When developing software for sshfs best options traders embedded series, the recommended workflow is to set up a cross-compiling environment. If you are in a rush to get stuff done, below you can see a sequence of commands that you can follow to have your device ready to go.
For a detailed device preparation, please refer to the following sections. It's best to sshfs best options traders from scratch for any kind of embedded development, so the first step is to download the images corresponding to the latest release for the device. For the following tutorial, sshfs best options traders is necessary that you can SSH into the embedded device from your development machine and vice versa.
For information on how to set up networking on the embedded device, consult the manual  - First boot. In the following, we will assume that the hostname of the development machine is desktopthe hostname of the embedded device is e3xx and the username on the development machine is dev.
You can update it by running the following command :. The "ettus" recipe provides the necessary elements for the E3XX, the gr-recipes repository provides all the other packages GNU Radio, out of tree modules, etc. On some distributions e. To avoid those problems, it is recommended to run the following command before continuing, and choose " no " in the prompted dialogue:. Keep in mind that this command will take a while to finish, due to the size and amount of files that need to be downloaded, cloned and installed.
After the installation is finished, proceed to the Running the new UHD via sshfs section. Sshfs best options traders your development machine, you will need to create a directory in which the development will take place. If you have not created it before, run the following sshfs best options traders.
Since you're cross-compiling i. Go the page where you downloaded the device image, and make sure you get the corresponding SDK. The files are quite big, so it can take a while to download them. The SDKs contain the compiler toolchain, but also contain libraries etc. This way, when compiling and linking, you know that what you compile on your development machine will also work sshfs best options traders the device.
It will ask you where to install sshfs best options traders to. Unzipping and installing takes a while. After it's done, you should see something like this:. Before running any of the following commands, you need to set up the environment as outlined on the device manual.
You need sshfs best options traders source the environment file:. As you can see, it will change all kinds of paths to use different compilers and libraries. Note that during this shell session, you won't be able to run a lot of other things on your development machines, so you should dedicate a separate shell window for this.
To cross-compile software, the SDK and the environment settings are usually not sufficient. Your software requires a toolchain setup at configuration time to build correctly. UHD brings support for this out of the box, so let's use UHD as an example on how to build custom software. Now, before we do the next step, confirm that you have the correct environment sshfs best options traders see the step before. We now need to configure the build setup to cross-compile correctly. This step might take longer than you're used to -- that's because sshfs best options traders is slightly slower than native compiles.
However, it's much, much faster than trying to compile on the device. The cleanest way to test your newly built UHD is to mount the prefix onto your embedded device. From your development machine, log onto the embedded device and mount the prefix:. Now, sshfs best options traders need to update the environment variables and paths in our ssh session on the embedded device.
You can see the contents is very simple -- all it does is point the most important paths into our prefix. Going back to the SSH session on the embedded device, you should be able to source that file now:. In the example above, it worked, and we're ready to go!
Everything that is related to the install is stored in the same directory, you can zip it up and move it another computer if you like, and the embedded device doesn't actually store any of the development files. As soon as you unmount the sshfs mount, and reset the environment, it will be back in its default state.
There are two ways to go ahead: To confirm that this worked, it can help to open the Sshfs best options traders configuration in a GUI and check that the UHD-related variables point to the correct libraries. To see more detailed information about the compile, click the "Advanced" checkbox. By doing so, a several number of configuration options appear, which can be not only read but also modified.
However, the development machine can be used to generate flow graphs and compile to Python. Again, the process is very similar to building GNU Radio. You must make sure that all the correct libraries are linked to, and that it doesn't accidentally pick up libraries from the SDK e.
