Got this building failure:
In file included from qemu-img.c:68:
qemu-img-cmds.h:22:1: error: unterminated argument list invoking macro
"printf"
cc1: warnings being treated as errors
qemu-img.c: In function ‘help’:
qemu-img.c:95: warning: statement with no effect
qemu-img.c:71: error: expected ‘;’ before string constant
qemu-img.c:95: error: expected statement before ‘)’ token
make: *** [qemu-img.o] Error 1
And git bisect figure out the commit: 84958305, "Enable _FORTIFY_SOURCE=2".
And the code is here:
printf("qemu-img version " QEMU_VERSION ", Copyright (c) 2004-2008 Fabrice
Bellard\n"
"usage: qemu-img command [command options]\n"
"QEMU disk image utility\n"
"\n"
"Command syntax:\n"
#define DEF(option, callback, arg_string) \
" " arg_string "\n"
#include "qemu-img-cmds.h"
#undef DEF
#undef GEN_DOCS
....
Seems gcc take "printf" as a marco. I added a "#undef printf" before the line,
then it works...
So any clue on what's happened and how to fix?
GCC version is 4.1.2.
