For those of us who don't read Chinese, Google Translate says that's

        Creating library libwireshark.lib and objects libwireshark.exp
        dissectors.lib (packet-ppp.obj): error LNK2019: unresolved external symbol _g_thread_init, the symbol is 
referenced in function _proto_register_ppp
        libwireshark.dll: fatal error LNK1120: 1 unresolved externals
        NMAKE: fatal error U1077: “"D:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\link.EXE"”: return code "0x460"
        Stop.
        NMAKE: fatal error U1077: “"D:\Program Files\Microsoft Visual Studio 9.0\VC\BIN\nmake.exe"”: return code "0x2"
        Stop.

(why "fatal error" is in English and "return code" isn't, well...).

What happens if you *don't* make that change, but, instead, change epan\Makefile.nmake to do something such as

libwireshark_LIBS = \
        $(GTHREAD_LIBS) \
        $(GLIB_LIBS)    \
        $(C_ARES_LIBS) \
        $(ADNS_LIBS) \
        $(KFW_LIBS) \
        $(NETTLE_LIBS) \
        $(ZLIB_LIBS) \
        $(GNUTLS_LIBS) \
        $(LUA_LIBS) \
        $(PYTHON_LIBS) \
        $(SMI_LIBS) \
        $(GEOIP_LIBS) \
        ..\wsutil\libwsutil.lib \
        ..\wiretap\wiretap-$(WTAP_VERSION).lib \
        crc\crc.lib \
        crypt\airpdcap.lib \
        ftypes\ftypes.lib \
        dfilter\dfilter.lib \
        $(WSLUA_LIB) \
        $(WSPYTHON_LIB) \
        dissectors\dissectors.lib

so that libwireshark is linked with $(GTHREAD_LIBS)?
