ByteStreamDriverModel Undefined Build Error With Latest Tutorial

[astroesteban]

Hi y'all,

I was going through the Hello World: Integration and Testing With F´ Deployments page just to get acquainted with the latest F Prime updates (the updates to prime-util are phenomenal by the way) and I keep getting this issue when trying to build the HelloWorldDeployment:

[ 97%] Generating HelloWorldDeploymentTopologyAppAi.xml, Ports_RateGroupsEnumAi.xml
fpp-to-xml
/workspace/MyProject/HelloWorldDeployment/Top/instances.fpp:108.27
  instance comDriver: Drv.ByteStreamDriverModel base id 0x4000 \
                          ^
error: undefined symbol ByteStreamDriverModel
gmake[3]: *** [HelloWorldDeployment/Top/CMakeFiles/HelloWorldDeployment_Top.dir/build.make:113: HelloWorldDeployment/Top/HelloWorldDeploymentTopologyAppAi.xml] Error 1

gmake: *** [Makefile:2418: HelloWorldDeployment] Error 2
[ERROR] CMake erred with return code 2

I'm using the latest F Prime version on devel (commit f34d596) and running the following commands:

cd MyProject/HelloWorldDeployment
fprime-util build -j $(nproc)

I also opted for the default responses when creating the component and deployment unless otherwise instructed by the tutorial.

Any thoughts as to what could be going wrong?

Ah! Yes, there has been changes in the devel branch. You will need to checkout the latest released version of F´ instead. Easiest way would be:

cd <project-path>/fprime
git fetch --tags
git checkout v3.3.2

[thomas-bc]

Or if you want to be working with devel, you can update the definition in your instances.fpp:

from

instance comDriver: Drv.ByteStreamDriverModel base id 0x4000 \
    type "Drv::TcpClient" \
    at "../../Drv/TcpClient/TcpClient.hpp"

to

instance comDriver: Drv.TcpClient base id 0x4000

Or TcpServer/LinuxUartDriver if you're using the TCPServer/UART option.

You can see how the changes were made to our test projects (RPI/Ref) here

Ah that makes sense! Got it working now. Thanks for the speedy response @thomas-bc! Much appreciated 👍🏼

@astroesteban how did you encounter this error? The tools are supposed to guide the user to a most-recent release tag...which should be consistent between the fprime-util and the version of F´  checked out.

Did you intentionally bump F´  to devel or how were you running off a dedicated tag?

[LeStarch]

Never mind. We've not released since this feature was implemented.

[astroesteban]

Yeah and I had just created a new project with fprime-util and defaulted to using the devel branch option when it asked what version of fprime I wanted to use.
