[QBS] How to connect COSMIC compiler

[Albion]

Tried to connect COSMIC compiler via QBS. But it only swears. Is there any tutorial on how to do this?

[jsulm]

@Albion What is Cosmic compiler and what does "connect" mean in this case?

[Albion]

@jsulm I have a stm8 project which correct builded in Cosmic IDE. And now I want to work with this project in Qt Creator, I add a cosmic compiler in setting, but when I am trying to build it (with Qbs) its didnt work. And the warnings on img above didnt talk anything.
p.s. In release 1.20 qbs have cosmic compiler support

Hi.

Unfortunately, I didn't add the Cosmic compiler support to QtCreator itself (I didn't have the time or desire ). The reason is that this compiler is rarely used (but you can add the task on QtCreator bug-tracker and then I will try, maybe). ;)

A good news is that you can add the Cosmic toolchain in QtCreator as Custom toolchain as follows:

• Make sure that the BareMetal plugin is enabled.

• Goto Tools->Options->Kits->Compilers->Add Custom->C:

  • Set desired compiler name (e.g. Cosmic (C)).
  • Choose path to the cxstm8.exe executable (in my case this was c:\COSMIC\FSE_Compilers\CXSTM8\cxstm8.exe).
  • Choose API unknown-baremetal-generic-unknown-unknown.
  • Click on Apply button.

• Goto Tools->Option->Devices->Devices->Add->Bare Metal Device:

  • Set desired sevice name (e.g. stm8).
  • Click on Apply button.

• Goto Tools->Options->Kits->Kits->Add:

  • Set desired kit name (e.g. COSMIC).
  • Set Device Type -> Bare Metal.
  • Set Device -> stm8.
  • Set Compiler C -> Cosmic (C).
  • Set Compiler C++ -> None.
  • Set Debugger -> None.
  • Set Qt version -> None.

Right now, you need to tell to Qbs that this custom compiler is cosmic for stm8 architecture (these names are special reserved in Qbs, this and this):

• Click on Change button in the Additional Qbs Profile Setitngs entry (in your Kit), and then:

  • Add entry for Key -> qbs.architecture; Value -> stm8.
  • Add entry for Key -> qbs.toolchain; Value -> cosmic.
  • Click on OK button.

• Click on Apply in your Kit.

Right now you need to check that the Qbs recognized that profile, goto Tools->Options->Qbs->Profiles, and then:

• Choose your COSMIC kit from the combo box.
• Make sure that its profile values are qbs.architecture is stm8, and qbs.toolchain is cosmic and also the compiler path is valid and the compiler names are cxstm8.exe.
• Other targetPlatform can be empty.

It should work. ;)

PS: Alternativelly, you can use the VSCode IDE with the Qbs extension, there are not need to make such configuration. ;)
PS2: If you is a Russian speacker, then you can ask direct questions in this Discord channel.

@kuzulis

Really thank you for helping me, but of couse I did all as you say and it didn`t work.

P.S. Reffering to discord server doesn`t work, maybe you can to send a invitation.

Really thank you for helping me, but of couse I did all as you say and it didn`t work.

You need to set the Show command line check-box in Build Steps of your Projects side pane options. Then we can see the real compiler invokes and they errors.

You can start at first from the simple main.c application.

Reffering to discord server doesn`t work, maybe you can to send a invitation.

Try this.

@kuzulis that what happens with just creating proj (only auto-generated main.c) :

build steps are empty:

P.S. If you prefer russian lang I would waiting in discord

[kuzulis]

Seems your Qbs configuration is wrong. Please show the Qbs profile settings (screenshoot with expanded items) for your Cosmic kit (from Tools->Options->Qbs->Profiles).

If you prefer russian lang I would waiting in discord

No, I will there a later.

@kuzulis

[jsulm]

@Albion C++ compiler is missing

[Albion]

@jsulm As Kuzulis say: "Set Compiler C++ -> None"

[kuzulis]

Hmm.. what's QtCreator version is? Need to use at least v6.0.2 (because there are Qbs 1.21).

[Albion]

@kuzulis
P.S. When I trying stm32 and arm-none-eabi-g++ compiler , I have the same problem

[kuzulis]

Try to re-start the QtCreator, then clear all *.user files from the sources of your project and then re-open your test project again from scratch.

[Albion]

@kuzulis not successfull but builing logs create new messages

[kuzulis]

Well, right now the Qbs invokes the cosmic compiler.

Seems, you need in the cosmic linker files *.lkf that is the cosmic-dependend stuff. Please read the cosmic compiler manual how to compile the simple application (what's you need for this).

Maybe you need in *.lkf stub as here.

Also, due to the COSMIC is an very outdated toolchain, then maybe you need to place your project with the short paths as possible (because the cosmic has a limitations for that).
