@ericLemanissier I got this error when building the test

error: #error "You must build your code with position independent code if Qt was built with -reduce-relocations. " "Compile your code with -fPIC (and not with -fPIE)."
 #  error "You must build your code with position independent code if Qt was built with -reduce-relocations. "\

How to check if qt package was created with -reduce-relocations or not ?

I got this error while working on my QArchive recipe and I ended up setting fPIC on the test package's CMakeLists.txt with no checks.

[prince-chrismc]

in other qt test packages, fPIC is usually enabled here

What causes this ?

Might have been an old bug? the last log I see is from March

Let's wait and see if it happens again or not and we will dive into the sources. A lot of things have changed since March.

[ericLemanissier]

the same thing happened: https://c3i.jfrog.io/c3i/misc/logs/pr/4528/15/qwt/6.1.6//02dd532ba76f7920165273b75f3536458790d051-build.txt ends with [HOOK - conan-center.py] post_package_info(): ERROR: [LIBRARY DOES NOT EXIST (KB-H054)] Component qwt::qwt library "libqwt_debug" not found in libdirs (https://github.com/conan-io/conan-center-index/blob/master/docs/error_knowledge_base.md#KB-H054) but the error was ignored and the bot and started the test recipe.

[jgsogo]

@ericLemanissier , The bug is related to the hooks: conan-io/hooks#299, it was not raising for post_package_info hooks.

[ericLemanissier]

@boussaffawalid do you have still some time to push this PR forward? If not I can apply some fixes on top of your branch

[boussaffawalid]

@ericLemanissier please feel free to help here.

[ericLemanissier]

@boussaffawalid I did a suggestion several days ago. My question is whether you still have some time to accept suggestions, if not, are you OK if I open another PR including your commits?

[boussaffawalid]

@ericLemanissier sorry I did not notice your suggestion. I just accepted it! Lets see how the build goes.
It is also absolutely fine to open another PR including my commits.

It was solved without modifying the recipe, just by restarting the build. Maybe it'll be as easy here ?

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}

I'm not sure why the bot continues to rebuild the same commit. The error seems to happen because qt encodes absolute path to its dependencies in files (.prl for example) during build, and these dependencies are not always at the same place when qt is consumed. This looks like QTBUG-72903 but it should already be fixed :/ I don't have much time for this currently, so if someone wants to investigate, (s)he should not hesitate !

EDIT: this is actually https://bugreports.qt.io/browse/QTBUG-87054

[jgsogo]

I've triggered this PR again after building qt/5.15.2 package that was missing. So then, it looks like the error is no longer on CI side, but on library/PR...

[ericLemanissier]

blocked by #5730

[ericLemanissier]

@boussaffawalid you can try to close and reopen this pr, to retrigger a build. It should pass now that #5730 is merged
