Setting up Eclipse to Develop Firmware
-
After doing what I said above, the latest error is in building the target ELF file:

arm-none-eabi-gcc: error: : No such file or directory make: *** [DuetWiFiFirmware.elf] Error 1I am not sure what file or directory it thinks is missing.

Evidently your Path in the C/C++ Build -> Settings -> Cross Settings still doesn't match the actual path to gcc on your computer. On my computer that path is set to:
C:\Program Files (x86)\GNU Tools ARM Embedded\6 2017-q2-update
and folder "C:\Program Files (x86)\GNU Tools ARM Embedded\6 2017-q2-update\bin" contains file arm-none-eabi-gcc.exe.
-
I checked the Path by right clicking RepRapFirmware, clicking properties, and going to C/C++ Build -> Settings -> Cross Settings
It was set to: /Users/John/Library/Arduino15/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin
The instructions say it should be this:
/Users/<your user="" name="">/Library/Arduino15/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/binSo looks correct.
When I go to that actual path, I see many arm-none-eabi- files and included in them are these:
arm-none-eabi-gcc
arm-none-eabi-g++
arm-none-eabi-gcc-4.8.3
and many more.There is no file extension. Mac says they are Unix Executables.
What on Earth is going on?</your>
-
In C/C++ Build > Settings, if I put the wrong path intentionally, this error comes immediately:
make all
/bin/sh: arm-none-eabi-g++: command not foundWhen I have the correct path, it successfully built cpp files, then the error comes after 19 seconds when it wants to "Build target: DuetWiFiFirmware.elf"
Just wish it would work!
-
The only difference I can see is that I left out the final "\bin" in the path I configured. Maybe Eclipse adds that itself?
I have another set of gcc files on my general PATH, and I've noticed that if I use the wrong path in Cross Settings, it picks up the compiler from those files (which is the wrong version compiler, so it doesn't work). Maybe in the linker step it is picking up gcc from that path too?
You could try putting the full path in the Command box in the Cross G++ Linker options, instead of just "gcc".
-
For the "arm-none-eabi-gcc: error: : No such file or directory" error, is it not finding arm-none-eabi-gcc?
Or is it not finding a file that is in the giant list of ".o" files?
Is "/Users/John/eclipse-workspace/RepRapFirmware/DuetWiFi/DuetWiFiFirmware.map" supposed to be an actual file, because I couldn't find it anywhere?
-
Ok, I will try what you said above.
-
Leaving out the "/bin" part resulted in no changes in the error.
For your other suggestion (putting full path instead of just gcc), I replaced gcc with arm-none-eabi-gcc (in the command box of the "Cross G++ Linker"). I got this error:
Building target: DuetWiFiFirmware.elf
Invoking: Cross G++ Linker
arm-none-eabi-arm-none-eabi-gcc -L"/Users/John/eclipse-worksp … [ … ] … robeProgrammer.o -lCoreNG -Wl,--end-group -lm -gcc
/bin/sh: arm-none-eabi-arm-none-eabi-gcc: command not found make: *** [DuetWiFiFirmware.elf] Error 127So it didn't work, so I'll change it back to just gcc.
-
For reference, when changing it back to just gcc, I get the same error as before. Although from the above error, it looks like it was looking in /bin/sh. So maybe I should put the gcc file in a folder called sh?

-
Notice the lone colon in the error?
arm-none-eabi-gcc: error: : No such file or directory
Maybe it was looking for a file or directory that had no name? Or had a space in the name or something?

Good catch! There is a "" after the -Wl,–start-group in your linker command line. When I'm in the office I'll see what should be there.

@jml:

This is a common mistake, due to poor error messages: in the first case, this is sh which can't find gcc, in the second case, this is gcc which can't find a file. sh reports which file it can't find (gcc, here), but gcc does not report the missing file…
I suspect a library path not setup correctly, so gcc can't find a .o to build something else.

So the file it's missing on your machine is, on my machine, "C:\Eclipse\Firmware\CoreNG\SAM4E8E\cores\arduino\syscalls.o". That should come from this "Command line pattern" setting in the Cross G++ Linker settings:
${COMMAND} ${FLAGS} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${LINK_FLAGS_1} "${workspace_loc:/${CoreName}/SAM4E8E/cores/arduino/syscalls.o}" ${INPUTS} ${LINK_FLAGS_2}
I've noticed before that if Eclipse can't find a file, it just omits it from the command line. If you built the SAM4E configuration of CoreNG before you built RRF, that file should be there.

Ok we are getting closer to a solution.
I found the missing file here:
/Users/John/eclipse-workspace/CoreNG/SAM4E8E/cores/arduino/syscalls.o
[it appears there with a bunch of other files after building CoreNG]In the RRF Cross G++ Linker "Command line pattern" box, I see this written:
${COMMAND} ${FLAGS} ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${LINK_FLAGS_1} "${workspace_loc:/${CoreName}/SAM4E8E/cores/arduino/syscalls.o}" ${INPUTS} ${LINK_FLAGS_2}Its the same as yours, so seems like its not a problem.
Maybe the problem is with how I build CoreNG and RRF:
- First I right click CoreNG, Build Configurations > Clean All.
- Repeat for RepRapFirmware folder
- Right click CoreNG, Build Configurations > Build Selected… then I select SAM4E8E and hit ok.
- Wait for build to finish (8 seconds)
- Repeat for RepRapFirmware folder, but select DuetWiFi and hit ok.
- Error
Should I build it differently?
-
That's the correct build order.
In Properties -> C/C++ Build -> Build Variables, do you have CoreName defined as CoreNG ?
-
For the RepRapFirmware folder, yes it is there. Name: CoreName || Type: String || Value: CoreNG
For the CoreNG folder, nothing is listed in the list. Should it be there?
-
I really just need to make some small firmware changes and some custom g-code commands.
I purchased the DuetWifi, PanelDue, and am waiting for the Duex5. Hoping to have it solved by the time it arrives! If I can't get it to work on Mac or Windows, I may just uninstall everything and try again when firmware version 1.2 is out.
Thanks for all the help you've provided so far!
-
I had no problem installing/compiling under linux. You may try to install a linux system in a Virtualbox env, and compile from there.
-
Ok, I will try. I'm using a decently powered Mac using Parallels to run windows and I assume I can put Linux on here too. Which Linux OS/distribution do you recommend? Ubuntu? I have limited experience with Linux, but I can learn!
