I want to build QEMU 4.2.0 with the plugin module on Windows 7 with Mingw, but the building process faild.
The step I follow is listed below:
1. create "dsp_build" diretory under source file folder
2.
change directory to dsp_build , and run ../configure
--target-list=dsp-softmmu --cross-prefix=x86_64-w64-mingw32-
--enable-gtk --enable-sdl --enable-debug --enable-plugins
3. build qemu project
4. running "make -C tests/plugin", yeilds error:
CC bb.o
D:/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/tests/plugin/bb.c:17:24:
error: variable 'qemu_plugin_version' definition is marked dllimport
17 | QEMU_PLUGIN_EXPORT int qemu_plugin_version = QEMU_PLUGIN_VERSION;
| ^~~~~~~~~~~~~~~~~~~
D:/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/tests/plugin/bb.c:17:24:
warning: 'qemu_plugin_version' redeclared without dllimport attribute:
previous dllimport ignored [-Wattributes]
5. I modified the QEMU_CFLAGS and the compilation command arguments($(CC) ..) in the makefile :
BUILD_DIR := $(CURDIR)/../..
include $(BUILD_DIR)/config-host.mak
include $(SRC_PATH)/rules.mak
$(call set-vpath, $(SRC_PATH)/tests/plugin)
NAMES :=
NAMES += bb
NAMES += empty
NAMES += insn
NAMES += mem
NAMES += hotblocks
NAMES += howvec
NAMES += hotpages
SONAMES := $(addsuffix .so,$(addprefix lib,$(NAMES)))
QEMU_CFLAGS += -fPIC -DBUILDING_DLL #added -DBUILDING_DLL
QEMU_CFLAGS += -I$(SRC_PATH)/include/qemu
all: $(SONAMES)
lib%.so: %.o
$(CC) -fPIC -shared -o $@ $^ $(LIBS)
# original command : $(CC) -shared -Wl,-soname,$@ -o $@ $^ $(LDLIBS)
6. Executing make yeilds:
make: enter ??/d/emu_devl/qemu_src/qemu-sr-dsp-a/qemu_tidsp_c3x/build_dsp/tests/plugin??

collect2.exe: error: ld returned 1 exit status
It is linker error, but I have no idea what goes wrong. My
collegue can build plugins on Ubuntu without any
problem. Any advise to build Plugins on Windows ?
Thanks.
