I would like to use the functionality which is described there. One of my commands for such a build try is working as desired. elfring@Sonne:~/Projekte/Linux/next-patched> git checkout next-20161014 && my_off=-O0 && for X in off; do my_output_dir=${my_build_dir}unchanged/optimisation/${X} && my_var="my_${X}" && my_parameters="-Wall -std=gnu89 -fomit-frame-pointer ${!my_var}" && make O="${my_output_dir}" HOSTCC='/usr/bin/gcc-6' HOSTCFLAGS="${my_parameters}" allmodconfig; done … # # configuration written to .config # I stumble on the following messages for another build command. elfring@Sonne:~/Projekte/Linux/next-patched> my_off=-O0 && for X in off; do my_output_dir=${my_build_dir}unchanged/optimisation/${X} && my_var="my_${X}" && my_parameters="-Wall -std=gnu89 -fomit-frame-pointer ${!my_var}" && LANG=C make V=2 O="${my_output_dir}" HOSTCC='/usr/bin/gcc-6' HOSTCFLAGS="-S ${my_parameters}" drivers/md/; done make[1]: Entering directory … HOSTCC scripts/basic/fixdep - due to command line change scripts/basic/fixdep: line 1: .file: command not found scripts/basic/fixdep: line 2: .comm: command not found … scripts/basic/fixdep: line 6: .section: command not found scripts/basic/fixdep: line 7: .align: command not found scripts/basic/fixdep: line 8: .LC0:: command not found scripts/basic/fixdep: line 9: .string: command not found … I wonder why this approach does not work so far. I would appreciate your advices. Regards, Markus
