The first problem is fixed by changing setting of PATH from "${BPATH}:${PATH}" to ${TMPPATH}. The second is fixed by using -nostdinc and setting strict include paths using -I directives to the compiler: CFLAGS="-nostdinc -I${WORLDTMP}/usr/include -I. -I${KERNSRCDIR}/dev/aic7xxx/aicasm" Can I get review on this patch? https://gist.github.com/anonymous/5493734 Inline: diff --git a/Makefile.inc1 b/Makefile.inc1 index e850cda..785e3180 100644 --- a/Makefile.inc1 +++ b/Makefile.inc1 @@ -830,17 +830,18 @@ buildkernel: @echo ">>> stage 2.3: build tools" @echo "--------------------------------------------------------------" cd ${KRNLOBJDIR}/${_kernel}; \ - PATH=${BPATH}:${PATH} \ + PATH=${TMPPATH} \ MAKESRCPATH=${KERNSRCDIR}/dev/aic7xxx/aicasm \ - ${MAKE} SSP_CFLAGS= -DNO_CPU_CFLAGS -DNO_CTF \ + ${MAKE} SSP_CFLAGS= -DNO_CPU_CFLAGS -DNO_CTF CFLAGS="-nostdinc -I${WORLDTMP}/usr/include -I. -I${KERNSRCDIR}/dev/aic7xxx/aicasm" \ -f ${KERNSRCDIR}/dev/aic7xxx/aicasm/Makefile # XXX - Gratuitously builds aicasm in the ``makeoptions NO_MODULES'' case. .if !defined(MODULES_WITH_WORLD) && !defined(NO_MODULES) && exists(${KERNSRCDIR}/modules) .for target in obj depend all + @echo "---- aicasm: ${target} ----" cd ${KERNSRCDIR}/modules/aic7xxx/aicasm; \ - PATH=${BPATH}:${PATH} \ + PATH=${TMPPATH} \ MAKEOBJDIRPREFIX=${KRNLOBJDIR}/${_kernel}/modules \ - ${MAKE} SSP_CFLAGS= -DNO_CPU_CFLAGS -DNO_CTF ${target} + ${MAKE} SSP_CFLAGS= -DNO_CPU_CFLAGS -DNO_CTF CFLAGS="-nostdinc -I${WORLDTMP}/usr/include -I. -I${KERNSRCDIR}/dev/aic7xxx/aicasm" ${target} .endfor .endif .if !defined(NO_KERNELDEPEND)
