on ubuntu compile windows 64bit error

[wawava]

Dear all
i try compile windows 64bit on Ubuntu 16.10, and i install depend

sudo apt-get install build-essential -y
sudo apt-get install nsis nsis-common -y
sudo apt-get install mingw-w64 mingw-w64-common mingw-w64-x86-64-dev -y

i find mingw use x86_64-w64-mingw32-gcc replace amd64-mingw32msvc-gcc,so i mod Makefile

ifneq (,$(shell which amd64-mingw32msvc-gcc))
	MING_BASE:=amd64-mingw32msvc-

to

ifneq (,$(shell which x86_64-w64-mingw32-gcc))
	MING_BASE:=x86_64-w64-mingw32-
else

then make TARGET=winagent , i get some error

i try to fix the problem, then i mod lua-5.2.3/src/Makefile.mingw

CC= i686-w64-mingw32-gcc
CFLAGS= -O2 -Wall -DLUA_COMPAT_ALL $(SYSCFLAGS) $(MYCFLAGS)
LDFLAGS= $(SYSLDFLAGS) $(MYLDFLAGS)
LIBS= -lm $(SYSLIBS) $(MYLIBS)

AR= i686-w64-mingw32-ar rcu
RANLIB= i686-w64-mingw32-ranlib
RM= rm -f

try replace all i686-w64-mingw32 to x86_64-w64-mingw32,then complie success
but install on windows 64bit system,ossec agent can't start,have some error, help me fix it,thanks
