Describe the bug
I'm maintainer of Bear in Gentoo, and tried to package version 3.1.6, but some files are now installed twice:

To Reproduce
Steps to reproduce the behavior:
Just try to build?

Expected behavior
install shouldn't install an extra copy of files

Environment:

Additional context

  • Can you give us a reference to the project that you are running against this tool? [e.g. No if it's a close source project, but in case of an open source project a link to the sources could be nice.]
  • What build tools this project is using? [e.g. GNU make wtih configure script]
  • What architecture you are trying to compile for? [e.g. cross compiling]
  • Could you attach build logs? If you can re-run the command which failed (e.g. bear -- make) with extra verbose log switches (e.g. bear --verbose -- make) and send the output of it, that would help a lot.

Attaching both versions for easy comparison

3.1.5-build.log
3.1.6-build.log

Before you send...

  • Have you read the README.md file or man bear?
  • Have you looked what other open issues Bear has?
  • Are you sure that the build works without Bear?

Hey @DarthGandalf , thanks for testing it... I agree that change needs to be reverted. Raised a PR for that: #626

Hi @rizsotto @DarthGandalf !

I don't think the change needs to be reverted, nor do I believe bear is being installed twice.

In my opinion, the issue lies in how CMake and Portage interact in this specific case. The project installs as expected, but an additional unstripped directory labeled "debug" appears. It seems that either Portage or the CMake cache used in Gentoo/Portage is causing CMake to install a debug version of the subproject alongside the main project.

I can't reproduce this issue with my CMake setup, which leads me to believe it may be related to unseen files in this bug report, such as the toolchain file or the CMake cache used with Portage.

"debug" is not the problem, it's there because I'm using FEATURES=splitdebug

mnt/ is still present if I disable this feature:

"debug" is not the problem, it's there because I'm using FEATURES=splitdebug

mnt/ is still present if I disable this feature:

I am sorry, but I don't see repeated files here! I see CMake installed the correct files under /usr and I see Portage didn't delete the temporary directory portagetmp. Please, correct me if I am wrong, I know absolutely nothing about Portage! I apologize in advance.

By the way, I am using CMake 3.31.6.

I am sorry, but I don't see repeated, installed files here

no worries

I see CMake installed the correct files under /usr and I see Portage didn't delete the temporary directory portagetmp

This whole subtree I'm showing is under /mnt/portagetmp/portage/dev-util/bear-3.1.6 - the "image" subdir of it is what would be installed to / later.

The point is, "make install" (or "ninja install"?) now copies the staged copy of ExternalProject to DESTDIR, while it didn't do that before addition of BUILD_ALWAYS. I don't know why it does that.

you can see in the log attached how this ExternalProject is installed:

What is the value of PORTAGE_TMPDIR when you invoke Portage? Have you tried removing BUILD_ALWAYS and running Portage on Bear 3.1.6? If the issue lies on BUILD_ALWAYS, I agree with disabling it through a command line option. I don't agree with removing the option completely because it has been pretty useful on our side, as it ensures we don't build a version of Bear that is outdated!

@DarthGandalf

PORTAGE_TMPDIR is /mnt/portagetmp for me, that's why it builds everything under that dir. It shouldn't copy that path under the image/ subdir though.

Yes, it works when I remove BUILD_ALWAYS, see https://github.com/gentoo/gentoo/pull/41304/files#diff-b3fcdcbbd9014dbf08a087cb1f6bf2e86a9c9bc3832d2038242962571c59adb4

@rizsotto what was the reason to use ExternalProject instead of add_subdirectory?

@inaki-amatria

Could you share all the configuration settings that Portage might be applying under the hood? I'd like to reproduce the issue locally. I strongly believe this is not related to BUILD_ALWAYS but rather to how it interacts with Bear's configuration within Portage. I noticed that you're using a custom toolchain and a cache, which were not included in your issue report. Please provide those details so I can investigate further.

Ultimately, this decision rests with @rizsotto, as he is the maintainer of Bear. However, the current configuration has been highly beneficial to us, our CI system, and likely any other developer who has recently modified the C++ codebase. Before the commit we are now proposing to revert, any changes made under Bear/source required reconfiguring the project for Make/Ninja to recognize them 😰.

How did you notice that? Because I don't use a custom toolchain nor a cache :)

I noticed that you're using a custom toolchain and a cache

How did you notice that? Because I don't use a custom toolchain nor a cache :)
Here's my /etc/portage/make.conf

and emerge --info

From 3.1.6-build.log:

. . .
cmake -C /mnt/portagetmp/portage/dev-util/bear-3.1.6/work/Bear-3.1.6_build/gentoo_common_config.cmake -G Ninja -DCMAKE_INSTALL_PREFIX=/usr -DENABLE_UNIT_TESTS=no -DENABLE_FUNC_TESTS=no -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_TOOLCHAIN_FILE=/mnt/portagetmp/portage/dev-util/bear-3.1.6/work/Bear-3.1.6_build/gentoo_toolchain.cmake /mnt/portagetmp/portage/dev-util/bear-3.1.6/work/Bear-3.1.6

That's not a cache.

The gentoo_toolchain.cmake is just how Portage handles cmake projects, to use the correct compiler.

I still can't reproduce the issue. What is the value of CMAKE_INSTALL_MODE when running Portage? https://cmake.org/cmake/help/latest/module/ExternalProject.html#install-step-options

I ask you to please run Portage with BUILD_ALWAYS enabled and with BUILD_ALWAYS disabled and run find /mnt/portagetmp/portage/dev-util/bear-3.1.6 -type f -exec sha256sum {} \; to see which files generated by CMake change when running with the option enabled or disabled... It looks like there may be some option that is set by Portage that interferes with the install step... I don't think the underlying issue is Bear setting BUILD_ALWAYS.

I see no changes in the generated files when trying to reproduce the issue. Thus, I believe the issue is with Portage and not with Bear enabling or disabling BUILD_ALWAYS...

The cmake eclass doesn't set CMAKE_INSTALL_MODE to anything

@DarthGandalf @inaki-amatria thanks to look into this! I do appreciate that you spend time to find a solution for this.

I am not really an expert on CMake... I still try to put my head around why would the BUILD_ALWAYS could cause the install target to act differently.

  • fedora build logs seems does not have this issue.
  • homebrew build file does not contain patch to disable BUILD_ALWAYS, presume they also does not have this issue.

Would you be ok with replacing ExternalProject with add_subdirectory?

@inaki-amatria

Thank you for your time and effort in investigating this, Alexey and László.

Based on the available evidence, this issue seems specific to Portage or the build recipe for Bear under Portage. As it has been pointed out, we cannot reproduce the issue elsewhere, and BUILD_ALWAYS should not lead to unexpected installation of targets.

Alexey, I understand that this behavior is undesired, but rather than modifying Bear to accommodate Portage, it might be more effective to investigate why Portage is causing repeated installation of targets. This may not be an isolated issue, as other projects under Portage could be affected in similar ways. By pinpointing the root cause, you could help remove unnecessary patches across multiple projects, saving Portage maintainers significant effort in the long run.

I would recommend trying to create a minimal reproducer with CMake and Portage to isolate the issue. Let us know if we can assist in that process.

what was the reason to use ExternalProject instead of add_subdirectory?

To me this is the right approach. The usage of ExternalProject is highly unusual.

I've made the decision to use ExternalProject instead of add_subdirectory in 2020. Don't remember the exact reason why. 😄 Changing from one to another is not a trivial task.

Long term, I am planning to replace the C++/CMake with rust/cargo. (ETA for that is in May this year.)

I would like to have no trouble to package the existing version. If that means I have to revert the BUILD_ALWAYS change, I would do that. If someone volunteer to make a PR to do the add_subdirectory change, I am happy to review and merge that too.

Changing from one to another is not a trivial task.

Well, it shouldn't be too hard. But if it's going to be replaced with rust in just 2 months, probably that doesn't worth the effort.
