c++ - How to resolve differences in methods in the .lib file? -

-

i trying 3rd party library work code. have source library, , have verified build options match own build options, have not gone though source code learn doing.

my code calls line value m_jsonvalroot; gives me following linking errors:

linking... 1>jsonwrapper.obj : error lnk2019: unresolved external symbol "public: __cdecl json::value::~value(void)" (??1value@json@@qaa@xz) referenced in function "public: class atl::cstringt<wchar_t,class strtraitmfc_dll<wchar_t,class atl::chtraitsos<wchar_t> > > __cdecl json::cjsonwrapper::runtest(class atl::cstringt<wchar_t,class strtraitmfc_dll<wchar_t,class atl::chtraitsos<wchar_t> > >)" (?runtest@cjsonwrapper@json@@qaa?av?$cstringt@_wv?$strtraitmfc_dll@_wv?$chtraitsos@_w@atl@@@@@atl@@v34@@z) 1>jsonwrapper.obj : error lnk2019: unresolved external symbol "public: __cdecl json::value::value(int)" (??0value@json@@qaa@h@z) referenced in function "public: class atl::cstringt<wchar_t,class strtraitmfc_dll<wchar_t,class atl::chtraitsos<wchar_t> > > __cdecl json::cjsonwrapper::runtest(class atl::cstringt<wchar_t,class strtraitmfc_dll<wchar_t,class atl::chtraitsos<wchar_t> > >)" (?runtest@cjsonwrapper@json@@qaa?av?$cstringt@_wv?$strtraitmfc_dll@_wv?$chtraitsos@_w@atl@@@@@atl@@v34@@z) 1>windows mobile 6.5.3 standard dtk (armv4i)\debug\ccrdex_ui.exe : fatal error lnk1120: 2 unresolved externals

i ran dumpbin on .lib file, , found function defined as: 

section header #c7    .text name        0 physical address        0 virtual address      194 size of raw data    22345 file pointer raw data (00022345 000224d8)    224d9 file pointer relocation table        0 file pointer line numbers       12 number of relocations        0 number of line numbers 60501020 flags          code          comdat; sym= "public: __thiscall json::value::value(enum json::valuetype)" (??0value@json@@qae@w4valuetype@1@@z)          16 byte align          execute read

i attempted resolve changing method declaration in headder file from: value( valuetype type = nullvalue ); __thiscall value( valuetype type = nullvalue );, had no impact on linker.

i building project in visual studio 2008 using mfc in shared dll, using unicode, , building windows mobile 6.5.3

what steps can take reslove linking issues?

i did forgetful when building lib files.

i accidently building win32 when needed building mobile device.

i'm developing internal application uses bluetooth printing. want bluetooth pairing occur without user input. have managed working trapping android.bluetooth.device.action.pairing_request broadcast. in broadcast receiver call setpin method, , pairing works ok, bluetoothpairingdialog displayed second or two, disappears - see link below. https://github.com/android/platform_packages_apps_settings/blob/master/src/com/android/settings/bluetooth/bluetoothpairingdialog.java since broadcast non-ordered, can't call abortbroadcast() , , wondering if there other way prevent pairing dialog appearing. can hook window manager in way? i haven't been able come way without modifying sdk. if you're oem, it's easy (i'm on 4.3): in packages/apps/settings/androidmanifest.xml, comment intent filter pairing dialog: <activity android:name=".bluetooth.bluetoothpairingdialog" android:label="@string/bluetooth_pairing_request"
