Scnaything - failed to build server

bcorley · December 14, 2023, 6:04pm

Les,
I’m attempting to get Scanything working on a linux butser machine running linuxcnc 2.9.1 and am having some issues. I commented out line 46 of main.cpp and am now getting this:

Why did you need to comment out line 46?

Do you have a run-in-place LinuxCNC installation? At a guess you have more than one LinuxCNC installation and the CNCRemote make file is getting confused as to which version is being used. Try running Scanything from within a RIP environment.

I commented line 46 because I get the error below and that’s what you suggested to do on another post.

10:25:32: Building src/main.cpp
10:25:34: src/main.cpp:46:12: error: âPACKAGE_VERSIONâ was not declared in this scope
10:25:34:  string a = PACKAGE_VERSION;

10:25:35: make: *** [makefile:34: obj/main.o] Error 1
10:25:35: Failed to build the server

I tried again, changing line 46 to the suggested alternative ‘MSGPACK_VERSION’ and got the same other errors:

Why do you think I have multiple linuxcnc versions installed? I have only upgraded from 2.9.0Pre to 2.9.1. That was done by removing the 2.9.0Pre install first, then, installing 2.9.0. Do you think there are residual files left from the original 2.9.0 install causing my issue? I would like to get this running on my current installation without having to port everything to a RIP install environment. There’s only 1 liblinuxcnc.a file. It looks like references are compiled into milltask. There is only 1 of them.

I also tried a fresh install of linuxcnc master 2.10 and got these errors:

I took a closer look into the affected files include/linuxcnc.h and src/linuxcnc.cpp and noticed that most of the errors should have their origin in differing naming conventions. Heading over to their github repository and having a quick glimpse over some source files revealed that instead of an underscore, in the newer versions the last attributes seem to get separated by two colons, f.e.

EMC_TASK_MODE_MDI is now EMC_TASK_MODE::MDI
EMC_TASK_STATE_ON is now EMC_TASK_STATE::ON

etc.

Well, these were quickly changed and after that only 3 error messages remained, yay:

I tried to find references to these messages, but quickly realized that these will need more insight… so i took the quick’n’dirty road and just commented out these lines as well as the following else-if loops. And that brought me to the known old error mentioned here before about a version mismatch in line 46 of main.cpp.

Commented that out as well…and et voila: Scanything was up and running together with LinuxCNC 2.9.3 and 2.10

I get constant messages about the client reconnecting to the server, but at least on a simulated machine this seems to work, the virtual machine in LinuxCNC moves while i manually move a camera.

If this helpful for further testing, here are the patches:

linuxcnc.h.patch.txt (535 Bytes)
main.cpp.patch.txt (277 Bytes)
linuxcnc.cpp.patch.txt (6.2 KB)

Well, finally came to test this on a working setup with LinuXCNC 2.10 from buildbot, and with the above patches applied → works fine

Note the constant “Machine running and homed” - “Machine not ready” messages in the log window, probably some stuff which needs to get fixed in the linuxserver component or in the main program. Apart from that → it works, except for the ability to save the results, of course.

Cheers,

Thanks for the input. I was able to get it running a while back, by the way, on Bookworm. Never on Buster.

Hey, glad to hear You got it running, do You remember under which LinuxCNC version?

Best Regards,

linuxcnc version 2.9.2 with debian Bookworm
Had to comment out line 46 in main.cpp
