And the couple of warnings I see compiling make me nervous too. I don't want to mess around too much until I'm sure I'm building it correctly, because I'd like to leave this machine bootable :) Other than that, if a fresh -current loader still doesn't fix my problem, I'm more than willing to start backing out recent commits to find which commit might be the problem. With 8.0-current sources as of a couple of hours ago, I get the same compile error trying any of these: cd /usr/src/sys && make cd /usr/src/sys && make boot cd /usr/src/sys/boot && make cd /usr/src/sys/boot/i386 && make all fail with: ... ===> i386/gptboot (all) ===> i386/kgzldr (all) ===> i386/libi386 (all) cc -O2 -fno-strict-aliasing -pipe -DLOADER_NFS_SUPPORT -DCOMPORT=0x3f8 -DCOMSPEED=9600 -DSMBIOS_SERIAL_NUMBERS -DTERM_EMU -Dalloca=__builtin_alloca -I/shared/src/sys/boot/i386/libi386/../../common -I/shared/src/sys/boot/i386/libi386/../btx/lib -I/shared/src/sys/boot/i386/libi386/../../../contrib/dev/acpica -I/shared/src/sys/boot/i386/libi386/../../.. -I. -I/shared/src/sys/boot/i386/libi386/../../../../lib/libstand/ -ffreestanding -mpreferred-stack-boundary=2 -mno-mmx -mno-3dnow -mno-sse -mno-sse2 -mno-sse3 -c /shared/src/sys/boot/i386/libi386/biosmem.c /shared/src/sys/boot/i386/libi386/biosmem.c: In function 'bios_getmem': /shared/src/sys/boot/i386/libi386/biosmem.c:61: error: 'SMAP_TYPE_MEMORY' undeclared (first use in this function) /shared/src/sys/boot/i386/libi386/biosmem.c:61: error: (Each undeclared identifier is reported only once /shared/src/sys/boot/i386/libi386/biosmem.c:61: error: for each function it appears in.) *** Error code 1 Stop in /shared/src/sys/boot/i386/libi386. *** Error code 1 Stop in /shared/src/sys/boot/i386. *** Error code 1 Stop in /shared/src/sys/boot. -- Mike Pritchard mpp @ FreeBSD.org "If tyranny and oppression come to this land, it will be in the guise of fighting a foreign enemy." - James Madison (1787)
