Conan Install issue

[princegeovision]

First of all, thank you for this template.

• I have trouble to run "Conan install"

conan install --profile:build=default --profile:host=debug --install-folder=build .

Result

ERROR: Profile not found: debug

• I believe maybe I should modify Profile to provide "build", "host" part. But I am also new to Conan as well.
• Any advice or link to documentation would be welcome.

My Conan profile (default)

Configuration for profile default:

[settings]
os=Macos
os_build=Macos
arch=x86_64
arch_build=x86_64
compiler=apple-clang
compiler.version=12.0
compiler.libcxx=libc++
build_type=Release
[options]
[conf]
[build_requires]
[env]

Thx for giving the template a try! It's the result of a hobby project of mine and I'm sharing it with others to get feedback about what could be improved! So if anything seems unclear or broken to you, pls keep asking! 😊

To answer your question:
My guess is that you don't have a debug profile defined.

You can create it by running conan profile new --detect debug. The new profile will be created in ~/.conan/profiles. You'll then need to adjust the build_type in the new profile to "Debug" like so: conan profile update settings.build_type=Debug debug.

This link might help you to understand how profiles in Conan work. There is also a section dedicated to the new profile:build and profile:host arguments.

If you are new to Conan I'd recommend you to get used to it in a more trivial setup for a few hours before getting your hands dirty on this repository. From my experience there is a lot things that can go wrong, especially once you are trying to add other dependencies. Getting everything right with all the cross-compiling to multiple different platforms is still causing me lot's of headaches, even after stabbing at it for about a year now. 🙈

Thank you for reply this detail information. I will looking into it.:smiley:

Thank's for the project!
I have a problem and it would be great if you can:

Happy New Year!

Can you provide me all steps that you did until getting this error message?

djinni-generated-files.txt seems to be missing, which leads me to the assumption that Djinni might not be installed correctly or an error might have occurred during the code generation.

Q: Which module generates djinni-generated-files.txt? I don't have this file. Also tried on another laptop - same error..

[andr-ggn]

I think this line doesn't work for me: tool_requires = [ "djinni-generator/1.3.0" ]

[jothepro]

djinni-generated-files.txt is produced by djinni during code generation. It reports a list of code files that have been generated, so CMake can pick them up. The CMake configuration fails because it does not find the file and therefore cannot configure the target. Likely the source files have also not been generated because djinni-generator recipe failed to install djinni.

Did you install the Conan version specified in requirements.txt? It is very much possible that the djinni-generator Conan recipe is broken in later versions of Conan, and unfortunately it is not actively updated anymore.

FYI I am currently working on replacing djinni, djinni-library-template and djinni_build with a new project that unites everything in one neat Python tool: https://github.com/pydjinni/pydjinni
It is still very WIP though, so I cannot (yet) recommend to use it.
