关于warning: Clock skew detected. Your build may be incomplete. 的解决方法

本文详细介绍了如何解决在编译Linux内核时遇到的关于时间差的警告问题。通过执行特定命令,可以修正系统时间与文件时间之间的不匹配,从而避免警告的出现。

       今天发现电脑的系统时间不对,因此将时钟进行了改动,回头编译Linux kernel的时候,提演示样例如以下的warning:

warning:  Clock skew detected.  Your build may be incomplete.

       第一感觉就是系统时间造成的,于是查找了一些资料。这个错误是因为系统时间比文件改动时间早造成的。

通俗点说就是,如今是下午三点。而你的文件的时间戳却是下午六点的,非常显然,这个是不太可能的事情,除非你能穿越。

       通过例如以下命令解决:

       find . -type f | xargs -n 5 touch
       make clean
       make



在WSL中编译C程序出现编译警告 root@DESKTOP-2QBDJV0:/mnt/d/work/openeuler_env/code/testUsbDongleRFID_pro# ./script/build.sh -- The C compiler identification is GNU 10.3.1 -- The CXX compiler identification is GNU 10.3.1 -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working C compiler: /mnt/d/work/openeuler_env/oecore-x86_64/sysroots/x86_64-peesdk-linux/usr/bin/aarch64-powereuler-linux-gcc - skipped -- Detecting C compile features -- Detecting C compile features - done -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Check for working CXX compiler: /mnt/d/work/openeuler_env/oecore-x86_64/sysroots/x86_64-peesdk-linux/usr/bin/aarch64-powereuler-linux-g++ - skipped -- Detecting CXX compile features -- Detecting CXX compile features - done -- Configuring done -- Generating done -- Build files have been written to: /mnt/d/work/openeuler_env/code/testUsbDongleRFID_pro/build make: Warning: File 'Makefile' has modification time 0.31 s in the future make[1]: Warning: File 'CMakeFiles/Makefile2' has modification time 0.28 s in the future make[2]: Warning: File 'CMakeFiles/run_testUsbDongleRFID.dir/flags.make' has modification time 0.21 s in the future make[2]: warning: Clock skew detected.
