Problem building Duet2

markz

I hate to post this since I should be able to get it working, but i've wasted a day and hoped you could help...

I'm just not able to build the latest (3.3) although I was fine building 3.2.

The build documentation is slightly inconsistent, so I'm not entirely sure what's required. It says to build 3.3 you need CoreN2G (3.3-dev) but I think I need CoreNG (dev). So, at the moment I now have both of them - but I've tried only one or the other as well with no success.

I've followed the build instructions carefully, but haven't reinstalled Eclipse. When I went back to (my) older code it built ok.

The build seems to work ok for all of the projects except RepRapFirmware.

If I don't have the CoreN2G project, when I run the build from Eclipse it doesn't give anything useful as an error (make all failed...) so instead I ran a command prompt and ran make all in the Duet2 folder and a bunch of files compile ok, but then I get...

If I do have the CoreN2G project I instead get this:

And I have no function_ref.h file that I can find anywhere so I'm confused.

Please help.

@markz looks like you have the wrong branch of RRFLibraries in your workspace. You need branch 3.3-dev.

markz

@dc42 Here's my library versioning unless there some caching that I can't see.

dc42

@markz if you are up to date with RRFLibraries 3.3-dev then function_ref.h should be in src/General.

markz

@dc42 Yay, thank you very much. It was a cascade of whack-a-mole.

a) It appears that I need both CoreNG and CoreN2G in the build. I set CoreN2G to Sam4e_sdhc and it built and seems ok (?)

b) for some reason my rrflibraries was 23 commits behind even though it spec'ed 3.3-dev (?) and I did a pull to update it. I had done this in earlier start-over tries, but without the CoreN2G it failed.

c) eclipse still won't build. I get this error:

08:20:31 **** Incremental Build of configuration Duet2 for project RepRapFirmware ****
make -j8 all 
c:/program files/gnu arm eclipse/build tools/2.6-201507152002/bin/sh: C:/Program: not found
make: *** [all] Error 127
makefile:96: recipe for target 'all' failed
"make -j8 all" terminated with exit code 2. Build might be incomplete.

08:20:33 Build Failed. 2 errors, 0 warnings. (took 1s.467ms)

but I can manually go to the Duet2 folder, run make all and it completes so. I suspect maybe my path is too long or there's a space character it doesn't like even though I'm using the gnu arm eclipse make. Ah well.

Thanks.

Mark

Addendum: apparently I don't need CoreNG anymore, since I just built ok without it. When you have time could you please update the table in section 15 of https://github.com/Duet3D/RepRapFirmware/wiki/Building-RepRapFirmware. Thanks so much.

@markz said in Problem building Duet2:

You do not need CoreNG in the build, it isn't used by RRF 3.3.

markz

@dc42 Yeah, thanks I just noticed. I really really appreciate the help.
