Hi, I started digging into why "make installworld" doesn't work when using the external toolchain support using CROSS_TOOLCHAIN= support. This is one of the big hurdles to just using 100% external toolchain using bapt's CROSS_TOOLCHAIN support. The TL;DR seems to be: * buildworld/buildkernel: CC gets set right; PATH doesn't include /usr/bin:/usr/sbin * installkernel: MACHINE is set, CC is not set (so it's 'cc') and PATH includes /usr/bin:/usr/sbin * installworld: MACHINE is set, CC is not set, PATH doesn't include /usr/bin:/usr/sbin The result is that during installkernel it finds 'cc' in /usr/bin and detects it as clang, even though I'm doing a mips-gcc build. During installworld it fails because it can't find 'cc'. So! In the short term, is there any way that during installworld/installkernel we can also set CC, etc appropriately? Otherwise we're either using the wrong compiler logic/version (installkernel) or we're just plain not going to work (installworld.) Also - why is PATH including /usr/bin:/usr/sbin when doing installkernel, but not installworld? To reproduce: * pkg install mips-gcc mips-xtoolchain-gcc mips-binutils * env MAKEOBJDIRPREFIX=/tmp/mips-obj make CROSS_TOOLCHAIN=mips-gcc TARGET=mips TARGET_ARCH=mips TARGET_CPUTYPE=mips32 DESTDIR=/tmp/mips-root -j 4 buildworld buildkernel installworld installkernel KERNCONF=MALTA ... make[4]: "/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/share/mk/bsd.compiler.mk" line 50: warning: "machine: mips, X_COMPILER_TYPE: , CC: cc" make[4]: "/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/share/mk/bsd.compiler.mk" line 96: warning: "Finished; COMPILER_TYPE=clang, COMPILER_VERSION=30700, COMPILER_FEATURES=c++11" .. so in the installkernel setup, the PATH includes /usr/bin which means 'cc' works, and thus it's detecting the compiler as clang even though we're supposed to be using mips-gcc. in the installworld setup, there's no /usr/bin in PATH, so it can't find cc. buildworld is ok: make[6]: "/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/share/mk/bsd.compiler.mk" line 50: warning: "machine: amd64, X_COMPILER_TYPE: , CC: cc" make[6]: "/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/share/mk/bsd.compiler.mk" line 96: warning: "Finished; COMPILER_TYPE=clang, COMPILER_VERSION=30700, COMPILER_FEATURES=c++11" ===> gnu/usr.bin/groff/src/devices/grops (obj) .. for the local stuff, and: make[5]: "/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/share/mk/bsd.compiler.mk" line 50: warning: "machine: mips, X_COMPILER_TYPE: , CC: /usr/local/bin/mips-portbld-freebsd11.0-gcc -isystem /home/adrian/work/freebsd/head-embedded-gcc5/src/../obj/mips_ap//mips.mips/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/tmp/usr/include -L/home/adrian/work/freebsd/head-embedded-gcc5/src/../obj/mips_ap//mips.mips/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/tmp/usr/lib --sysroot=/home/adrian/work/freebsd/head-embedded-gcc5/src/../obj/mips_ap//mips.mips/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/tmp -B/usr/local/mips-freebsd/bin/" make[5]: "/usr/home/adrian/work/freebsd/head-embedded-gcc5/src/share/mk/bsd.compiler.mk" line 96: warning: "Finished; COMPILER_TYPE=gcc, COMPILER_VERSION=50200, COMPILER_FEATURES=c++11" .. for the building mips stuff. So installkernel works only "by magic" because of PATH, and CC is just not being set right for installkernel/installworld. ok, so what now? :) -adrian
