[Qemu-devel] The error from compiling QEMU statically

[wj193102]

Hi, everybody.
I want to compile QEMU statically. But when I make the soure files, I get the error messages. Please help me to resolve them.
Now I will tell you the steps what I do.
(1)$ cd qemu-3.0.0
(2)$ ./configure --prefix=/usr --static
(3)$ make
When I input the "make" command, and  run it, then I get the error messages.
(1)/block/file-posix.c:1945: Error: There is an unknown field 'prealloc' in the initializer;
(2)/block/file-posix.c:1946: Error: There is an unknown field 'errp' in the initializer.
How to resolve these problems, please help me, thanks.

Can you share the output of the configure script?

What is your distribution?

I can not reproduce your problem (using Fedora).

Note that static compilation is only really supported for
building the linux-user emulators, not for the system
emulators. So it's best to pass configure options to tell
it to only build the linux-user emulators, like
--disable-system --disable-tools

(1)/block/file-posix.c:1945: Error: There is an unknown field
'prealloc' in the initializer;
(2)/block/file-posix.c:1946: Error: There is an unknown field 'errp'
in the initializer.

Which compiler is this? Google provides no hits for
this error message, which suggests you're using something
weird, rather than gcc or clang.
