------- Additional Comments From [EMAIL PROTECTED] 2002-12-30 02:46 ------- Created an attachment (id=74) --> (https://qa.mandrakesoft.com/attachment.cgi?id=74&action=view) preprocessed source I realised this is how to attach the preprocessed source file ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------- Reminder: ------- assigned_to: [EMAIL PROTECTED] description: The problem is with gcc-3.2-1mdk (came with Mandrake 9.0), but I do not know how to upgrade to gcc-3.2-4mdk; I would be happy for someone to tell me how to. I got this error when compiling linux kernel 2.4.20 patched with linux-abi 2.4.18: -------------------- gcc -D__KERNEL__ -I/D0/home/lwedding/src/linux-2.4.20/include -Wall -Wstrict- prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame- pointer -pipe -mpreferred-stack-boundary=2 -march=athlon -nostdinc - iwithprefix include -DKBUILD_BASENAME=sysi86 -save-temps -c -o sysi86.o sysi86.c gcc: warning: -pipe ignored because -save-temps specified sysi86.c: In function `svr4_sysi86': sysi86.c:133: warning: dereferencing `void *' pointer sysi86.c:133: warning: dereferencing `void *' pointer sysi86.c:133: warning: dereferencing `void *' pointer sysi86.c:133: warning: dereferencing `void *' pointer sysi86.c:133: warning: dereferencing `void *' pointer sysi86.c:133: Internal compiler error in emit_move_insn_1, at expr.c:3106 Please submit a full bug report, with preprocessed source if appropriate.
