:(, another redefinition, 'RAMBlock' also defined in
'include/exec/cpu-all.h:314',
Am i miss something when compile qemu?
Interesting; I'm not seeing that problem at all (gcc 4.8.3-7)
What compiler and flags are you using?
Dave
Hi Dave,
My compiler info:
gcc (SUSE Linux) 4.3.4
The configure info is:
#./configure --target-list=x86_64-softmmu --enable-debug --disable-gtk
...
CFLAGS -pthread -I/usr/include/glib-2.0
-I/usr/lib64/glib-2.0/include -g
QEMU_CFLAGS -fPIE -DPIE -m64 -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64
-D_LARGEFILE_SOURCE -Wstrict-prototypes -Wredundant-decls -Wall -Wundef
-Wwrite-strings -Wmissing-prototypes -fno-strict-aliasing -fno-common
-Wendif-labels -Wmissing-include-dirs -Wempty-body -Wnested-externs
-Wformat-security -Wformat-y2k -Winit-self -Wignored-qualifiers
-Wold-style-declaration -Wold-style-definition -Wtype-limits
-fstack-protector-all -I/usr/include/libpng12 -I/usr/include/pixman-1
LDFLAGS -Wl,--warn-common -Wl,-z,relro -Wl,-z,now -pie -m64 -g
...
Maybe its gcc's limitation, but why this redefinition need? After i remove one,
it compiles successfully;)
Thanks,
zhanghailiang
