https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D223180 Bug ID: 223180 Summary: Bug in kmod.mk when SRCS is empty/not defined Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: conf Assignee: freebsd-bugs@FreeBSD.org Reporter: johalun0@gmail.com I discovered a bug/flaw in kmod.mk when building a kernel module where I do= not have any c source files. Objects files are built using Rust and specified in OBJS variable. If SRCS is empty/not defined these lines # Conditionally include SRCS based on kernel config options. .for _o in ${KERN_OPTS} SRCS+=3D${SRCS.${_o}} .endfor generate an entry in SRCS with one space: SRCS=3D" " Causing this line to add a " .o" to OBJS.=20 OBJS+=3D ${SRCS:N*.h:R:S/$/.o/g} Which of course cause the make command to fail since there is no ".o" file. By replacing it with these lines I could temporary fix the problem. .for _o in ${SRCS} OBJS+=3D${_o:R:S/$/.o/g} .endfor --=20 You are receiving this mail because: You are the assignee for the bug.=
