[Qemu-devel] getting link errors when building for qga-vss.dll

[Kirk Allan]

When I try to build qga-vss.dll I get the following link error:

LINK    qga/vss-win32/qga-vss.dll
/usr/lib64/gcc/i686-w64-mingw32/8.2.0/../../../../i686-w64-mingw32/bin/ld: qga/vss-win32/requester.o: in function `requester_freeze':
/src/qemu/qga/vss-win32/requester.cpp:284: undefined reference to `g_assertion_message_expr'

I started getting this link error with commit 3ebee3b191e755d3f7311a6a62eea5c9628b221b where assert is redefined to g_assert.

Is there something additional I need to add to my configure or make commands to resolve g_assertion_message_expr?

My configure command is: ./configure --cross-prefix=i686-w64-mingw32- --enable-guest-agent --with-vss-sdk

My make command is: make qemu-ga.exe qga/vss-win32/qga-vss.dll

Thanks,
Kirk

Hi Kirk,

I've sent a patch to fix this here:

  https://patchwork.kernel.org/patch/10682937/

but it was recommended we take a different approach that I wasn't able to
get working in time for 3.1. So you might need to make use of the
posted patch in the meantime. The final fix should go in shortly after
the 3.1 release next week.
