How to import projects in eclipse, Windows

thehans

I'm attempting to follow the BuildInstructions.md for windows, but I don't regularly use eclipse.

Step 12 says to just import the projects into eclipse, but under the File->Import menu there are dozens of options, I don't know what is the correct procedure so that it has any idea how to build CoreNG.

Can anyone elaborate on exact steps to import these projects correctly?

Also Step 5 says to use "which", but that is not a windows command. I used "where" instead and that seems to verify the path.
Do I need any other not-mentioned GNU tools installed for this?

Currently if I try to build CoreNG it is trying to use autoreconf and failing to find it:

Invoking autoreconf in build directory: C:/Eclipse/Firmware/CoreNG/

sh -c "autoreconf -i" 
sh: autoreconf: not found

Configuration failed with error

It's File->Import->Existing projects into workspace. You might also be able to use File->Import->Git, I haven't tried.

I've never heard of autoreconf. Which version of Eclipse C/C++ are you using?

OK I deleted the CoreNG folder and started over with "Existing projects into workspace" and now CoreNG seems to build ok (using SAM4E8E build config for Duet 2 Wifi)

Then I try to build DuetWifiSocketServer|Release and it returns this:

13:43:27 **** Incremental Build of configuration Release for project DuetWiFiSocketServer ****

When I try to build ReprapFirmware|Duet2 I get errors like this:

../src/Storage/FileStore.cpp:295:25: error: 'micros' was not declared in this scope
  uint32_t time = micros();
                         ^

...etc (too long to include in forum post)

Make sure that you are using the current branches of the various projects. See https://forum.duet3d.com/topic/7464/problem-building-firmware-for-duet-wifi/7.

You don't need to build DuetWiFiSocketserver in order to build ReprapFirmware, but you do need the DuetWiFiSocketServer project to be present in the workspace.

OK, it looks like the build succeeds for RepRapFirmware now.

I didn't realize I should have been making changes in v2-dev branch, and I had been using the dev branch, so I'm moving the code over to v2-dev now.

For the stepper brake feature I'm working on, you suggested to use a signature similar to ConfigureStallDetection, which has changed between these two branches.
Right now I'm confused about the difference in usage for StringRef reply vs OutputBuffer outBuf. Could you explain?

dc42

You only need to use OutputBuffer if the response is likely to get very long. Most commands don't need to use it. So stick with StringRef.
