Weird problem building the 2014.08 toolchain in i686-lucid
Hi,
I'm having some very odd problems building the 2014.08 toolchain respin --
in the cbuild1 i686-lucid env, building glibc fails with
[ERROR]../sysdeps/unix/sysv/linux/bits/sched.h:127:14: error:

(Yes, the fix is to get rid of cbuild1 and more importantly the requirement
for 32-bit builds in a prehistoric environment - it builds just fine on
64-bit present-day boxes... But I don't think we want to make that change
in a respin).
The "variably modified" errors remain even after hardcoding
typedef struct {
__cpu_mask __bits[16];
} cpu_set_t;
instead of relying on __CPU_SETSIZE and __NCPUBITS, and the line where it
complains about alignment not being a positive power of 2 actually
hardcodes an alignment of 16.
Have you run into those before?

Re: Weird problem building the 2014.08 toolchain in i686-lucid
I fixed a problem in the i686 build recently, but the symptom was
different from your: GCC itself failed to build.
Maybe it's worthing try 09 release (which will probably be announced today)

[ANNOUNCE] Linaro GCC 4.9 2014.09 released
The Linaro Toolchain Working Group (TCWG) is pleased to announce the 2014.09 release of the Linaro GCC 4.9 source package. Linaro GCC 4.9 2014.08 is the sixth Linaro GCC source package release. It is based on FSF GCC 4.9.2-pre+svn214896 and includes performance improvements and bug fixes. With the imminent release of ARMv8 hardware and the recent release of the GCC 4.9 compiler the Linaro TCWG will be focusing on stabilization and performance of the compiler as the FSF GCC compiler. The Linaro TCWG provides stable[1] quarterly releases and monthly enginering[2] releases. Interesting changes in this GCC source package release include * Updates to GCC 4.9.2-pre+svn214896 * Backport of [AArch32] TARGET_ATOMIC_ASSIGN_EXPAND_FENV hook * Backport of [AArch32] Enable arm target in ira-shrinkwrap-prep* testcases * Backport of [AArch32] fix check_effective_target_arm_nothumb * Backport of Do not convert cast + __builtin_round into __builtin_lround unless -fno-math-errno is used * Backport of [AArch64] Fix Thumb2 testsuite fallout * Backport of [AArch64_be] Fix vec_select hi/lo mask confusions. * Backport of [AArch64_be] Don't fold reduction intrinsics * Backport of [AArch64] Fix offset glitch in load reg pair pattern * Backport of [AArch64][2/2] Add constrain to address offset in storewb_pair/loadwb_pair insns * Backport of [AArch64] Improve TARGET_LEGITIMIZE_ADDRESS_P hook * Backport of [AArch64] Removed unused get_lane and dup_lane builtins. * Backport of [sched-deps] Generalise usage of macro fusion to work on any two insns * Backport of [doc] Document clrsb optab and fix some inconsistencies * Backport of [AArch64] Some aarch64-builtins.c cleanup. * Backport of Guard transformation to lrint by -fno-math-errno * Backport of [AArch32] Adjust clz, rbit and rev patterns for -mrestrict-it * Backport of [AArch32/AArch64] Add CRC32 scheduling information to Cortex-A53 and Cortex-A57 * Backport of [AArch64] Use REG_P and CONST_INT_P instead of GET_CODE + comparison * Backport of [AArch64] Prefer dup to zip for vec_perm_const; enable dup for bigendian; * Backport of [AArch32] TARGET_ATOMIC_ASSIGN_EXPAND_FENV hook * Backport of [AArch64] Use MOVN to generate 64-bit negative immediates where sensible * Backport of [AArch64] Delete f_sels, f_seld types, use fcsel instead * Backport of PR target/60606 target/61330 fix ICE * Backport of [AArch64] PR target/63190 Feedback and Support Subscribe to the important Linaro mailing lists and join our IRC channels to stay on top of Linaro development. ** Linaro Toolchain Development "mailing list": http://lists.linaro.org/mailman/listinfo/linaro-toolchain ** Linaro Toolchain IRC channel on irc.freenode.net at @#linaro-tcwg@ * Bug reports should be filed in Launchpad against "Linaro GCC project": http://bugs.launchpad.net/gcc-linaro/+filebug. * Questions?
