Description
Parallel builds of Qt for x64 starts failing when attempting to upgrade from Qt 6.4 to 6.5.
Dockerfile to reproduce:
# Based on https://github.com/emscripten-core/emsdk/tree/master/docker FROM emscripten/emsdk:3.1.27 AS qtbuilder RUN mkdir -p /development # Install Mesa OpenGL (needed to build Qt for x64) RUN apt-get update && apt-get -y install mesa-common-dev libgl1-mesa-dev libglu1-mesa-dev # Clone Qt sources WORKDIR /development RUN git clone --branch=6.5 https://code.qt.io/qt/qt5.git WORKDIR /development/qt5 RUN git rev-parse HEAD RUN ./init-repository # Build Qt for x64 RUN mkdir -p /development/qt5_build_x64 WORKDIR /development/qt5_build_x64 RUN /development/qt5/configure -nomake examples -nomake tests -prefix /usr/local/Qt-x64 RUN cmake --build . --parallel 4 RUN cmake --install .
Build error encountered:
Step 12/13 : RUN cmake --build . --parallel 4 ---> Running in ed496c7be5c2 gmake[2]: *** No rule to make target 'qtbase/libexec/syncqt', needed by 'qtbase/src/corelib/Core_syncqt_timestamp'. Stop. gmake[1]: *** [CMakeFiles/Makefile2:14348: qtbase/src/corelib/CMakeFiles/Core_sync_headers.dir/all] Error 2
Reproduced on commit f6b1bf3c96c2bbfcbcfa390f927d100620543987 dated 2023-02-14. See attached build_log.txt for more details.
Work-arounds
The problem can be worked around by either downgrading to the 6.4 branch or reducing the number of build executors from 4 to 1.
