Setting up Eclipse to Develop Firmware

[jml]

I do see the sam4e.h file in this directory:

/Users/John/eclipse-workspace/CoreNG/asf/sam/utils/cmsis/sam4e/include/sam4e.h

[jml]

I right-clicked CoreNG, clicked Properties, and added the following path to both Cross GCC Compiler and Cross G++ Compiler Includes "Include paths (-I)":
/Users/John/eclipse-workspace/CoreNG/asf/sam/utils/cmsis/sam4e/include/

Also, I am enclosing it in quotes because thats how the other ones are.

That got rid of the sam4e.h error. But the new error is:

Once again, I see that the file does exist here:
/Users/John/eclipse-workspace/CoreNG/variants/duetNG

So what is going on?

[jml]

So I saw that in the CoreNG Cross G++ and GCC compiles, this was in the Includes (I-) lists:
"${workspace_loc:/${ProjName}/variants/duet}"

So I added:
"${workspace_loc:/${ProjName}/variants/duetNG}"

That got rid of the error. New error is:

Which is followed by many more errors such as this:

So I would rather not fidget around with it further or else I'll just make it worse.

Hopefully someone can help!

[dc42]

It appears that somehow your .cproject file has been corrupted, because it was including the wrong variants folder, and the folders for other variants are not being excluded.

[jml]

Hi dc42, maybe that is the case. Not sure. But I ended up fixing the CoreNG problem. But please tell me if I did something that I definitely should not have:

Ok, I removed "${workspace_loc:/${ProjName}/variants/duet}" and replaced it with "${workspace_loc:/${ProjName}/variants/duetNG}"

Then CoreNG would finally build without errors!

The same errors would occur with building RepRapFirmware, so I did the same things and that got rid of the same errors. New errors:

12:28:23 **** Build of configuration DuetWiFi for project RepRapFirmware ****

^
compilation terminated.
make: *** [src/Tools/Filament.o] Error 1

12:28:23 Build Finished (took 185ms)

So I did this change in the RepRapFrimware Cross GCC/G++ Compiler Includes (-I) lists:
"${workspace_loc:/${ProjName}/src/Duet}" changed to "${workspace_loc:/${ProjName}/src/DuetNG}"

Then it got very far in the build process. Many warnings about implicit conversion from float to double in the CoreXY Kinematics part.

Then got an error with Network.h not in path. So I added to the (-I) lists:
…RepRapFirmware/src/DuetNG/DuetWiFi because I found Network.h there.

Will keep using the same fix for each error that will come up. dc42, can you tell me if I am heading down the wrong path? Should I not use DuetNG files in the path?

[jml]

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 1

I am not sure what file or directory it thinks is missing.

[dc42]

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.

[jml]

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/bin

So 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>

[jml]

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 found

When 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!

[dc42]

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".

[jml]

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?

[jml]

Ok, I will try what you said above.

[jml]

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 127

So it didn't work, so I'll change it back to just gcc.

[jml]

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?

Building target: DuetWiFiFirmware.elf
Invoking: Cross G++ Linker
arm-none-eabi-gcc -L"/Users/John/eclipse-w … [ … ] … rc/ZProbeProgrammer.o -lCoreNG -Wl,--end-group -lm -gcc
arm-none-eabi-gcc: error: : No such file or directory
make: *** [DuetWiFiFirmware.elf] Error 1

Interesting how the prior error was "command not found", but then this error is "No such file or directory."

[jml]

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?

[dc42]

@jml:

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.

[fma]

@jml:

Interesting how the prior error was "command not found", but then this error is "No such file or directory."

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.

[jml]

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?
