https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225182 --- Comment #23 from Kenneth Salerno <[email protected]> --- I want to add two somewhat related notes here. 1. At some point devel/binutils started using a BUTARGET?= ${PKGNAMEPREFIX}unknown-${OPSYS:tl}${OSREL} which equates to CROSS_BINUTILS_PREFIX= /usr/local/bin/powerpc64-unknown-freebsd11.1- in my environment, where previously I was used to seeing CROSS_BINUTILS_PREFIX= powerpc64-freebsd- (devel/amd64-binutils forces this previous behavior I was used to with BUTARGET= x86_64-${OPSYS:tl}) The net of this is I had a CROSS_BINUTILS_PREFIX pointing to nowhere. Fixed that in my make.conf. Still have RELEASE-11.1 kernel blowing up with gcc5&6 either way, but want to ensure I'm using binutils 2.30. 2. This one is a complete mystery to me: if I set KERNCONF, even if I copy GENERIC64 exactly, I get the Data Storage Exception in SLOF. If I copy my kernel config to overwrite GENERIC64 (and not set KERNCONF) the kernel will boot normally, if built with the system compiler (again, still getting Data Storage Exception with gcc5&6 no matter what configuration I use). To reproduce error with system compiler: cp /usr/src/sys/powerpc/conf/GENERIC64 /usr/src/sys/powerpc/conf/SALERNO make buildkernel __MAKE_CONF=/dev/null __SRC_CONF=/dev/null KERNCONF=SALERNO ARCH=powerpc TARGET_ARCH=powerpc64 (this kernel will cause a Data Storage Exception) Then take the custom kernel config and overwrite GENERIC64: cp /root/kernels/SALERNO /usr/src/sys/powerpc/conf/GENERIC64 make buildkernel __MAKE_CONF=/dev/null __SRC_CONF=/dev/null ARCH=powerpc TARGET_ARCH=powerpc64 (this kernel will boot normally) 3. Previously in RELEASE-11.0 and older, I could build and boot a kernel excluding CTF. Now with 11.1, I get a Data Storage Exception if I do this, forcing me to build including CTF. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "[email protected]"
