Can't compile project

[thekingisback-code]

When compiling the code (make) the following error is generated

It says make: find: Command not found, so you may need to install find in your system. Or add it to the Dockerfile.

It also says invalid origin for memory. Have a look at this issue, which probably fixes that.

Also, make sure you follow the "Compiling" instructions in the documentation. That means: make docker and make libopencm3 before make. If you still get errors, report them back here. :blush:

Hey there @Peque, I apologize but I'm new at this and its kind of hard debugging when I'm not really sure what I'm doing (and trust me, I'm googling everything I do).

It says make: find: Command not found, so you may need to install find in your system. Or add it to the Dockerfile.

Find is already installed, I don't really know how to check for the version, but when I type find --version it returns

usage: find [-H | -L | -P] [-EXdsx] [-f path] path ... [expression]
       find [-H | -L | -P] [-EXdsx] -f path [path ...] [expression]

and while it doesn't output the version (wrong syntax I believe) which kind of means it's correctly installed.

Then I check where it is with which find and it outputs '/usr/bin/find' With echo $PATH I verify the directory is inside. /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/Apple/usr/bin:/Library/Apple/bin:/opt/X11/bin I tried adding it to the Dockerfile just like find \ (in the appropriate line, of course) and after running make dockerthis was the output

Complete!

Still, I proceeded to compile libopencm3 using make lipopencm3 and mid-compilation it outputted Makefile:66: Your toolchain doesn't support -mcpu=cortex-m7. Please use gcc-arm-embedded 4.8 2014q3 or newer. Skipping this sub-library.which I suspected was because it was using the standard gcc on my system, which is 4.2.1. I added an Alias in the Dockerfile as follows RUN alias gcc='g++-9'which seemed logic at the moment, but it did not fix the problem. Now I'm truly lost.

It also says invalid origin for memory. Have a look at this issue, which probably fixes that.

I modified `src/stm32f103x8.ld` as the issue suggested and while it improved, now it outputs
/usr/lib/gcc/arm-none-eabi/9.2.0/../../../../arm-none-eabi/bin/ld: main.elf section `.text' will not fit in region `rom'
/usr/lib/gcc/arm-none-eabi/9.2.0/../../../../arm-none-eabi/bin/ld: region `rom' overflowed by 5280 bytes
collect2: error: ld returned 1 exit status
make: *** [opencm3/libopencm3.rules.mk:204: main.elf] Error 1
make: *** [src/main.elf] Error 2

which to be honest, it could be carrying the errors from not completely compiling libopencm3, but I don't truly know. Should I upload the files or something in specific?

Once again, I truly appreciate you taking the time to answer back.

[Peque]

Does make docker output any errors? That is the first command that should succeed. I mean, once the image is correctly generated, everything else should work just fine.

Make sure to git checkout -- Dockerfile first, just to make sure you have a clean Dockerfile before starting. In fact, discard any changes you have locally to see if we can make at least the image generation work. :blush:

[thekingisback-code]

Docker doesn't output any errors whatsoever.

That's without running git checkout -- Dockerfile So as far as I know, the image generation works @Peque

[Peque]

Let us concentrate on the make libopencm3 error then. Until that is fixed you should not try to compile the project.

Please, do execute git checkout -- Dockerfile to regenerate the clean/unmodified image from the Dockerfile included in Bulebule's repository.

Can you share the full output of the make libopencm3 command once you regenerate the (clean/unmodified) image? Share it through Gist, please.

[thekingisback-code]

Heres the complete session of my terminal, @Peque .

[Peque]

Ok, it does not look too bad! ^^

I do not understand why you get that error when compiling for the F7 family (I do not, and theoretically, using the Docker image, we should be compiling libopencm3 with the same toolchain). :confused:

Anyway the F7 family is not required to build the project so:

• Can you share the output of make
• Also the output of docker --version

[thekingisback-code]

Ok, it does not look too bad! ^^

There's hope! lol

Anyway, here's the new output, @Peque (Should I keep on tagging you?, btw) https://gist.github.com/thekingisback-code/f56e97c9d96af12dd3e9771b85c37e23

[Peque]

Okay, I do not know much about Docker, but I find it weird that you get different outputs than me. I, for instance, can compile for the F7 family and I do not get the "find: Command not found" error... :confused:

You now need to apply the fix in https://github.com/Bulebots/bulebule/issues/416. That is for sure.

Try replacing the arm-none-eabi-gcc with arm-none-eabi-gcc-cs-7.4.0 in the Dockerfile and see if that helps (share the new output).

You can also try adding findutils to the list of packages installed in Dockerfile and try again? (share the output again).

[Peque]

No need to tag me now. Once I start posting in an issue, I get automatically subscribed. :wink:

[thekingisback-code]

In lines 875-876 it now outputs the error after applying the fix in #416 and in line 869 a new error is introduced, which to be honest looks promising, sounds easier to fix. But who am I to say, at this point, I don't really understand that much.

My full terminal session is here and the new Dockerfile is here

[Peque]

Yeah, that line looks like maybe you need to clean the (pre)compiled libopencm3 files. Maybe you should try to reset the project (i.e.: create the directory, clone, make libopencm3 and make again). Not very efficient, but maybe the safest way to ensure we are on the right track. :joy:

[thekingisback-code]

Took the long way home and reset the project (created the directory, cloned, make docker, make libopencm3 and make again...) and this is the output, now it only overflows, pretty sure it's related to fix #416.

Here's the terminal session.

[thekingisback-code]

Somehow I closed it (whatever it means), but... nope.

[Peque]

I can now reproduce the error, which is good news! :blush:

I think I was using my (old) cached Docker image, which probably had different packages installed.

This means we may be able to fix this by setting the version of other package(s) in the Dockerfile. I would say the package we need to set to an older version is probably arm-none-eabi-newlib. But not sure which version it should be. :sweat_smile:

[thekingisback-code]

Anything I can do to help on my end? Seriously dude, I owe you a coffee/beer.

[Peque]

Yeah, mostly because I am about to disconnect, and I do not think I will be able to spend much time with this until, probably, next Sunday. :innocent:

Have a look at the newlib Koji packages. Look for the .fc30 packages (Fedora 30).

I would first try with the 3.0.0 version. Install it with:

dnf install arm-none-eabi-newlib-3.0.0-5.fc30.noarch.rpm

You will need to edit the Dockerfile again to include this package installation in your image. I would add a new RUN line before the RUN alias, so you do not need to regenerate the image from zero.

[thekingisback-code]

Worry not, I'll try to do it all by myself and I'll update the issue as necessary mid-week.

You will need to edit the Dockerfile again to include this package installation in your image. I would add a new RUN line before the RUN alias, so you do not need to regenerate the image from zero.

This doesn't sound that hard, so I'll try!

Thanks!

[Peque]

Actually, it seems that may not be necessary. Simply replace arm-none-eabi-newlib with arm-none-eabi-newlib-3.1.0-2 in the Dockerfile and try. :blush:

[Peque]

I meant arm-none-eabi-newlib-3.1.0-2.fc30. Otherwise dnf will not find the package.

[Peque]

@thekingisback-code Please, try these changes and tell me if that works fine: https://github.com/Bulebots/bulebule/pull/420
