Hello, I have access to a relatively old Itanium cluster, which I do not control, and am trying to build 4.6 (0 and 1) as well as the current trunk, but I keep getting bootstrap failures; I am stuck with a snapshot of trunk from last January, some time after that it just stopped building. This is the error message: =============================================================== make[2]: Entering directory `/home3/pasqua/GNUBUILD/obj-4.6.1' make[3]: Entering directory `/home3/pasqua/GNUBUILD/obj-4.6.1' rm -f stage_current make[3]: Leaving directory `/home3/pasqua/GNUBUILD/obj-4.6.1' Comparing stages 2 and 3 warning: gcc/cc1-checksum.o differs warning: gcc/cc1plus-checksum.o differs Bootstrap comparison failure! gcc/insn-emit.o differs gcc/sel-sched-ir.o differs make[2]: *** [compare] Error 1 make[2]: Leaving directory `/home3/pasqua/GNUBUILD/obj-4.6.1' make[1]: *** [stage3-bubble] Error 2 make[1]: Leaving directory `/home3/pasqua/GNUBUILD/obj-4.6.1' make: *** [bootstrap] Error 2 [pasqua@n64 obj-4.6.1]$ uname -a Linux n64 2.4.21-15.11hp.XCsmp #1 SMP Wed Dec 22 09:45:49 EST 2004 ia64 ia64 ia64 GNU/Linux ================================================================ Any suggestions as to what to try next? Thanks a lot Salvatore
