[nurcses|doxygen] : doxygen don't have support for gcc version 9 in conan v2

Description

I have encountered an issue with Conan v2 ( 2.0.7 to 2.6.0) where certain packages do not support the following configuration:

[settings] arch=x86_64 build_type=Release compiler=gcc compiler.libcxx=libstdc++11 compiler.version=9 os=Linux

This issue is specific to GCC version 9 on Linux Ubuntu 20.04. The lack of support for this configuration in Conan v2 is problematic as it affects the following packages:

doxygen/1.9.4#e623a1e90a2d4b84ef87786161ce1b5d:eeb1b51ffeea6c954ff777fd2f24c79e122d09b9 doxygen/1.8.17#6dc34583abd89ead45db1407b15e2c38:eeb1b51ffeea6c954ff777fd2f24c79e122d09b9 ncurses/6.4#78908f3ed548f188cf15e415f8949f2f:ce9018589f291698a25f5ae23c3e0676d2ad6408

Impact:

The inability to use these packages with the specified settings hinders our ability to maintain consistency across our development environments, as GCC 9 is a widely used compiler version in our Linux builds.

Request:

Could support for GCC 9 on Ubuntu 20.04 be added for these packages in Conan v2? If there are any workarounds or configurations that could be applied in the meantime, that information would be greatly appreciated.

Thank you in advance !!

Hi @sabapathim thanks a lot for taking the time to open the issue.

What you're experiencing is not a lack of support of those recipes to your configuration, but just a missing binary for your given profile. This means that Conan does not build and upload packages for gcc 9, so if you need to use these packages, you'll need to ask Conan to build those packages in your machine for you (Usually adding --build=missing would be enough to tell Conan to build any missing packages, not just these, that are not provided by any of your remotes)

I hope this helps, let me know if you have any follow-up question, happy to help where possible :)

Hi @AbrilRBS,

Thank you for taking the time to respond to my issue.

I’ve tried the build option, and it works perfectly for me. However, within my organization, there are over 300 users using these packages, and requiring each of them to build the package is not ideal. This is why I’m requesting a pre-built binary for GCC 9.

Please let me know what can be done in this situation. If necessary, I’m willing to contribute by building the binary for GCC 9 myself. Could you guide me through the process I should follow to create a doxygen package compatible with GCC 9?

Thank you for your assistance.

Hello @AbrilRBS I see the cmake package don't have any compiler version fixed for linux , it was able to worked perfectly, https://conan.io/center/recipes/cmake?version=3.30.1

But I see the conan configuration for the linux gcc is fixed to 11 for conan2 here. How the cmake alone able to be a exception from that setting ?

For Conan 2 we currently only publish binaries for gcc11, and it is very unlikely that we will publish binaries for versions earlier than that. We will reconsider this once we stop supporting Conan 1.x and free up resources to support additional configurations. There will be an update on this later this year. We appreciate that Ubuntu 20.04 is still used - however there are two more recent Ubuntu LTS after that one and there is a limit as to how far back it makes sense for us to go.

How the cmake alone able to be a exception from that setting ? The cmake recipe uses pre-built binaries and erases the compiler setting, so there are matching binaries for os and arch combinations, irrespective of the compiler versions.

there are over 300 users using these packages, and requiring each of them to build the package is not ideal.

I would encourage your company to read our documentation on how you can host your binaries: https://docs.conan.io/2/devops/using_conancenter.html and https://docs.conan.io/2/tutorial/conan_repositories.html to support your teams needs, some of which are free - like Artifactory CE.

We try to support a wide user base - but we are unable to support all configurations.

Hello @jcar87 ,

Thanks for your response and it was quiet helpful,

I tried doxygen in ubuntu 22.04 , where gcc version is 11

I encountered the below error.

conan install --requires doxygen/1.9.4 -r conancenter

And yes I'm aware of the build option which you told earlier, just want to know , though I have suitable settings, what went wrong !!.

Thanks for your response in advance @jcar87 !!
