How to get the toolchain up and running? #422

Closed louis-etne closed 1 year ago

louis-etne commented 1 year ago

Hi, I'm trying to compile any example from this project, but it seems that I can't get the toolchain correctly installed:

Ada_Drivers_Library/examples/STM32F429_Discovery
$ gprbuild -P blinky_f429disco.gpr 
gprconfig: can't find a toolchain for the following configuration:
gprconfig: language 'ada', target 'arm-eabi', runtime 'embedded-stm32f429disco'
stm32f429_discovery_full.gpr:61:25: warning: libraries are not supported on this platform
common.gpr:1:09: no compiler for language "Ada", cannot compile "last_chance_handler.adb"
gprbuild: *** compilation phase failed

I downloaded the gnat-arm, as required by the README:

$ arm-eabi-gnat --version

What did I missed? I have the same error in gnatstudio.

Hi,

What does the output of the following command report:

arm-eabi-gnatls -v --RTS=embedded-stm32f4

Best regards,

Hi, Thanks for your answer!

This is what i get:

OK, that's all good, so the toolchain installation itself seems good to go, although not necessarily all the runtimes you might want. But I still am not convinced that it is as expected.

If you try to build the blinky project for the STM32F4 Disco board (not the 429), does that work? In the STM32F4_DISCO directory, try this:

gprbuild -P blinky_f4disco.gpr

This will try to build with a different target board and runtime, as a test.

Hi, I tried every example without any success and the same error each time:

language 'ada', target 'arm-eabi', runtime 'embedded-stm32f429disco'

(the target and the runtime changed of course, but the error was the same)

OK, thanks for trying that one.

Let's get some more info. Add "-v" to the end of the gprbuild command (without the quotes). What does that display?

pat-rogers commented 1 year ago

Hi Louis,

For the sake of comparison to your setup, I did the following to verify the downloads and overall approach.

I created a new Ubuntu virtual machine.

In that VM I created /usr/gnat/arm-elf/ (via the sudo command). The directory names themselves are not important, it's just what I am used to.

I downloaded gnat-arm-elf-linux64-12.2.0-1.tar.gz for the toolchain itself and expanded/untarred it into the above, resulting in these subdirectories:

├── arm-eabi

├── bin

├── include

├── lib

├── lib64

├── libexec

└── share

I then put /usr/gnat/arm-elf/bin/ on the PATH in my .profile file. Instead of just doing "source .profile" to update the PATH value I logged off and then back on, so that the effect would be global across the couple of terminal windows I wanted to use.

Next I downloaded gprbuild-x86_64-linux-22.0.0-1.tar.gz for gprbuild, expanded it locally, CD'd into it, and then ran the installer:

sudo ./doinstall

That adds more files under the same subdir names as the compiler, ie bin/, libexec/, and share/. Therefore I took the installer option to put it in a specific location, and specified the same location as the compiler, in other words /usr/gnat/arm-elf/. As a result it added the gprbuild-specific files to those existing subdirs.

Next, I cloned the Ada Drivers Library. Once done, I opened a terminal at Ada_Drivers_Library/examples/STM32F4_DISCO and built the blinky example:

gprbuild -P blinky_f4disco.gpr

That all worked as expected. I then did the same with the F429 Disco blinky example.

So, how does your installation differ from the above?

Best regards,

Pat Rogers

Hi, with more information I get:

I have exactly the same folder structure for my gnat-arm toolchain. I installed it in ~/.local/bin and then added it to my path in my .bashrc. I reinstalled gprbuild, not using dnf (I'm on fedora) but via the installer, to have the exact same version as you (and a more recent one). I still have the issue:

$ which gprbuild
/usr/local/bin/gprbuild
$  gprbuild -v -P blinky_f4disco.gpr

Again, thanks for your time.

Hi,

Thanks for trying that experiment. This is very strange indeed, but it is almost certainly a setup issue in some form. Something is conflicting.

Please issue the following command and send the resulting output (it will be a lot of info, hopefully):

gprconfig --batch --target=arm-elf --config=ada,, -v

Best regards,

Pat Rogers

For some reason, on your installation gprconfig does not see all the runtimes included with the arm-elf compiler. The output I get in my VM from that same command is much, much more extensive, as a result.

In particular there should be many runtimes located here:

<cross compiler installation root>/arm-eabi/lib/

In my case:

/usr/gnat/arm-elf/arm-eabi/lib/

and gprconfig should find them, but it does not on your installation. Your output just has this:

Do you have those runtime directories under arm-eabi/lib/ ?

Assuming so, there must be some other installation causing conflict.

At this point I am grasping at straws: I suggest renaming directories on the PATH, iteratively, to see if one of them contains the culprit.

Be sure to delete any such .cgpr files you find in the dirs in which you've run the gprconfig tool.

For that matter, is it possible that there is an existing .cgpr file that is in play? That would certainly explain things.

Just to be certain there was nothing I was missing in our two setups, I did it all over again in a new VM, and this time installed into /usr/local. It all worked, so there is some difference we're missing.

Sorry for the delay of this answer but thanks to your precious help, I finally have a running GNAT ARM toolchain!

The issue was that I created a symlink for each executable of the bin directory of the downloaded gnat-arm-elf-linux64-12.2.0-1.tar.gz to my conventional bin (~/.local/bin/gnat/*) directory (thus avoiding the modification of the PATH each time I need new binary).

Doing this, gprconfig was completly lost and couldn't find its lib directories. Maybe resolving the symbolic link before searching for directories?

Anyway, thank you so much. :)

That's great news!
