Hi


Hello, everyone!
      I build spice vdagent as [1] in fedora28, but it
              failed as [2], I'm a truly newbie in windows,
that's helped if I can get some document or a build
              flow. 

[1]
# sudo apt-get install mingw-w64-x86-64
              mingw64-filesystem mingw64-cximage-static
              mingw64-jasper-static mingw64-libjpeg-turbo-static
              mingw64-libpng-static mingw64-libtiff-static
              mingw64-zlib-static mingw64-winpthreads-static

# ./autogen.sh

# ./configure
              CXXFLAGS=-I/usr/x86_64-w64-mingw32/sys-root/mingw/include
CXIMAGE_CFLAGS=-I/usr/x86_64-w64-mingw32/sys-root/mingw/include/CxImage
              CXIMAGE_LIBS=-ljasper -ljpeg -lpng -ltiff -lz -lcximage
              LDFLAGS=-L/usr/x86_64-w64-mingw32/sys-root/mingw/lib
              CXX=x86_64-w64-mingw32-g++ CC=gcc
CxImage requirement was removed time ago using libpng
          directly (also considering that CxImage is not more maintained
          and contains security issues).
Why you are passing CXIMAGE flags?
To cross compile is better to use the --host option, like

 ./configure --host=x86_64-w64-mingw32

in Fedora there's a very useful script called
          "mingw32-configure" (or "mingw64-configure") which calls
          configure with the correct
settings to cross compile with MingW


    thx, it works well in master branch.

add follows to Makefile:
WINDRES = x86_64-w64-mingw32-windres
EXEEXT = .exe

# make

Why using LTO?
Looks like you are using an older version, looking at your
          previous e-mail you
have the correct git repository but you are not using
          master.


        I download it from
    https://www.spice-space.org/download/windows/vdagent/vdagent-win-0.8.0/,

    and we are using the vdagent provided by
    oVirt-toolsSetup-4.2-1.el7.centos.iso, is the vdagent build 

    from master code will works well with the other program provided by
    oVirt-toolsSetup-4.2-1.el7.centos.iso?

    if so, we can use the newest version rather than
    vdagent-win-0.8.0(or others version).
Yes, is full compatible.
