I try to build an iso image from release 3.5 branch and get following error. What's wrong? bash-4.4# make kernel make -C kernel/linux-4.19.61 mrproper make[1]: Entering directory '/mnt/kernel/linux-4.19.61' make[2]: *** Documentation/Kbuild: Is a directory. Stop. make[1]: *** [Makefile:1316: _clean_Documentation] Error 2 make[1]: Leaving directory '/mnt/kernel/linux-4.19.61' make: *** [Makefile:98: kernel/linux-4.19.61/arch/x86/boot/bzImage] Error 2 Wawrzek PS. Is it correct that master points on Crux 3.4 release? -- Dr Wawrzyniec Niewodniczański or Wawrzek for short PhD in Quantum Chemistry & MSc in Molecular Engineering WWW: http://wawrzek.name E-MAIL: jobs@wawrzek.name Linux User #177124
