WinCairo and PlayStation builders are rarely observing the following error. https://build.webkit.org/#/builders/731/builds/1945 > ninja: error: build.ninja:35: loading 'CMakeFiles\rules.ninja': The system cannot find the file specified. > include CMakeFiles\rules.ninja > ^ near here 1934993 1 fujii 2023-02-19 14:28:34 -0800 I don't know how this problem appears. But, it's easy to reproduce the error by removing WebKitBuild/{Debug,Release}/CMakeFiles directory manually. However, this problem doesn't happen if I remove both CMakeFiles directory and CMakeCache.txt. It executes cmake to regenerate in such a case. removeCMakeCache actually removes both. Weird. https://github.com/WebKit/WebKit/blob/5a049809955a360f7ec43aa244acc1e65b4b70e6/Tools/Scripts/webkitdirs.pm#L2683-L2684 > unlink($cmakeCache) if -e $cmakeCache; > rmtree($cmakeFiles) if -d $cmakeFiles; 1935000 2 fujii 2023-02-19 16:04:27 -0800 Steps to reproduce: 1. Invoke .\Tools\Scripts\build-webkit CMakeLists.txt and CMakeFiles directory are created. 2. Add "message(FATAL_ERROR)" to Source/cmake/OptionsCommon.cmake 3. Invoke .\Tools\Scripts\build-webkit CMakeLists.txt and CMakeFiles directory are removed. Only CMakeLists.txt is created. 4. Invoke .\Tools\Scripts\build-webkit Report the ninja error 1935004 3 fujii 2023-02-19 16:24:30 -0800 Bug#165008 introduced this bug. And, CMake 3.8 fixed the CMake problem. https://gitlab.kitware.com/cmake/cmake/-/issues/13934#note_200624 https://gitlab.kitware.com/cmake/cmake/-/commit/25b6e7b710d7739cca44ed19bf45a190e72a6b82 I'm going to revert the WebKit change. 1935005 4 465079 fujii 2023-02-19 16:43:12 -0800 Created attachment 465079 Patch 1935012 5 clopez 2023-02-19 18:07:01 -0800 (In reply to Fujii Hironori from comment #4) > Created attachment 465079 [details] > Patch I don't understand why or how this patch would work. As far as I can see what CMake developers did on 3.8 was to also purge the CMakeFiles directory if the CMakeCache.txt file was removed, which is also basically what the current code in the script 'build-webkit' does. So why patching the script 'build-webkit' to not remove the CMakeFiles directory fixes the problem? CMake is also supposed to remove this directory in any case, doesn't it? I'm confused, sorry 1935014 6 fujii 2023-02-19 18:34:41 -0800 IIUC, it removes ${CMAKE_BINARY_DIR}/CMakeFiles/${CMAKE_VERSION} directory. https://gitlab.kitware.com/cmake/cmake/-/blob/master/Source/cmGlobalGenerator.cxx#L584 rules.ninja is not removed becaused it is in ${CMAKE_BINARY_DIR}/CMakeFiles directory. 1935056 7 465079 mcatanzaro 2023-02-20 05:55:10 -0800 Comment on attachment 465079 Patch View in context: https://bugs.webkit.org/attachment.cgi?id=465079&action=review Fujii, I think you might be the only developer still attaching patches to Bugzilla. :P > COMMIT_MESSAGE:11 > +And, the original CMake proglem was fixed by CMake 3.8. problem 1935181 8 465090 fujii 2023-02-20 11:51:48 -0800 Created attachment 465090 Patch 1935218 9 465093 fujii 2023-02-20 12:42:05 -0800 Created attachment 465093 [fast-cq] Patch 1935232 10 ews-feeder 2023-02-20 13:18:18 -0800 Committed 260563@main (4e08fdf96101): <https://commits.webkit.org/260563@main> All reviewed patches have been landed.
