(In reply to Benjamin Réveillé from comment #5) Same patch works here, too.
The trigger seems to be ninja. dev-build/ninja-1.12.1 -> broken dev-build/ninja-1.11.1-r5 -> works https://github.com/ninja-build/ninja/releases/tag/v1.12.0 "Critical path scheduler which orders the jobs by their runtime history #2177 This may break your build if you haven't specified your dependencies correctly." So, somewhere a dependency is really missing in doxygen and the new ninja scheduler will then build it in the "wrong" order.
Created attachment 897279 [details, diff] fix for incorrect dependency declaration The attached patch fixes the build problem for me. And I was even able to remove the -j1 restriction from the second build call. (8 core / 16 thread ryzen using -j16. So it should be OK for any -j) The problem seems to be, that the doxygen call expects all files already copied to the target build directory. And as part of the DEPENDS declaration this should have been the case. But while all other DEPENDS specify the full path to the needed files, in the case of the doxygen call only the pure filename was listed. So cmake / ninja could not construct the correct dependency and the copy before doxygen only happend due to luck and the -j1 was needed so, that all copys where finished before the doxygen call. After adding the full paths the dependency now seems to get calculated correctly and it works both with the new ninja and without needing -j1.

Then again my solution is not working anymore either...
(In reply to Benjamin Réveillé from comment #9) > With this patch and ebuild modification I am still failing with "error: > @INCLUDE = baseexample.cfg: not found!" I think that should be a different problem, baseexample.cfg != example.cfg The build system is using "baseexample.cfg" for each example as a base for the per example configuration. As one of the examples has the name "example", this one then uses "example.cfg" as its configuration and that was, what originaly was failing, because this "example.cfg" has not yet been copied to the build tree. The copy of "baseexample.cfg" is organized by a different build rule, that rule worked OK for all of my tests. https://github.com/doxygen/doxygen/blob/master/examples/CMakeLists.txt#LC10 -> [line 10] build rule for baseexample.cfg https://github.com/doxygen/doxygen/blob/master/examples/CMakeLists.txt#LC17 -> [line 17] that should copy any files per example directory, including example.cfg for the "example" example. https://github.com/doxygen/doxygen/blob/master/examples/CMakeLists.txt#LC81 -> [line 81] wrong DEPENDS: It only lists ${f}.cfg for example.cfg without a path and then ninja was ignoring the need to copy the cfg before building the "example" documentation. I just retried the build on my system: Still works for me. Did you apply any additional local patches? For the proposed patches: The attached patch for CMakeLists.txt is necessary. Otherwise the DEPENDS is wrong and the newer ninja versions will reorder the build steps in a way that does not work. The patch for the ebuild itself is not really needed to get it to work. It only removed the "wrong" fix for the DEPENDS problem that bug #770070 added. That fix worked with the old ninja versions, because by building it one step at a time without parallelism, by "random" change a working order was chosen. With the fixed DEPENDS that restriction is no longer useful, as ninja now only can generate correct orders. And keeping the -j1 would just slow down the build.
The problem is still present in the doxygen-1.11.0 ebuild, and "cmake_src_compile examples" still helps in 1.11 .

Tried it again (patch + ebuild modification together as the first time) tonight and it worked :-) So tried it again for repeatability and it failed :-( Triedit a third time and it worked ;-) So still a race condition somewhere :-(

Created attachment 898145 [details] modified doxygen-1.11.0.ebuild As for the equivalent 1.10.0 solution (patch+ebuildmodification), this also works most of the time but sometimes fails so there seems to remains a race conditions.
