ANT+ integration in my QT project

NicuPopescu

first, you need to compile the whole ANT_Windows_Library_Package_v3.2, then in ANT_Windows_Library_Package_v3.2/Debug you'll find the dll(ANT_DLL.dll) its export library ANT_DLL.lib and the static library ANT_Lib.lib for static building(no dll used)

DEMO_DLL uses ANT_DLL.dll and ANT_DLL.lib which is just an export library for dll and other few .lib files (see Additional Dependencies in VS project Linker->Input)

DEMO_LIB uses ANT_Lib.lib which is a static library(all static code will be in DEMO_LIB.exe) and check how big is its size compared to ANT_DLL.lib

Oh i'm starting to understand.

I have compiled the whole project "ANT_Windows_Library_Package_v3.2", In the debug folder, I have the lib you mentioned. Now let's say I want to use "ANT_LIB.lib" in a Demo project I just created, how do you actually use the "ANT_LIB.lib" in another project? I have tried the below project; Demo Project.pro, that is actually the project DEMO_LIB that I imported in QtCreator),
Thanks very much, tell me you paypal account for your payment :)

So what is the difference between using a static lib or a dll? I will probably use the static lib since it seems easier for me (I don't mind the bigger size)

I linked the static library ANT_LIB.lib in my pro file

New Demo_lib.pro :

@TEMPLATE = app
CONFIG += console

Now I have error like :
ANT_LIB.lib(dsi_serial_generic.obj):-1: error: LNK2038: mismatch detected for '_MSC_VER': value '1800' doesn't match value '1600' in demo.obj
This seems to be because the static lib was compiled with VStudio express 2013, not the same compiler that QtCreator use

I did compile ANT_LIB successfully with QTCreator using this setup :

ANT_LIB.pro
@---------------

QT -= gui

TARGET = ANT_LIB
TEMPLATE = lib

CONFIG += staticlib

DEFINES -= UNICODE

include (inc/inc.pri)
include (libraries/libraries.pri)
include (common/common.pri)
include (software/ANTFS/ANTFS.pri)

include (software/system/system.pri)
include (software/USB/USB.pri)
include (software/USB/device_handles/device_handles.pri)
include (software/USB/devices/devices.pri)

When I try to run DEMO_LIB, I now get this error message :
ANT_LIB.lib(WinDevice.obj):-1: error: LNK2019: unresolved external symbol __imp__CharNextA@4 referenced in function "struct IdEntry __cdecl GetIdType(char const *)" (?GetIdType@@YA?AUIdEntry@@PBD@Z)

Almost there! I learned a lot today, sorry for the spam, just keeping a log for myself/maybe to help others

NicuPopescu

ANT_LIB.lib may compile but this does not necessarily mean that was linked correct to all required dependent libs: I mean this might be discovered later when other project is compiled against it and does calls to lib functions calling farther other functions from other libs .... is recommended to understand into which libs the unreferenced functions reside and take care the all libs where added in LIBS while compiling ANT_LIB

Thanks Nicu, I am on my way to debugging this error

_ANT_LIB.lib(WinDevice.obj):-1: error: LNK2019: unresolved external symbol ___imp__CharNextA@4 referenced in function "struct IdEntry cdecl GetIdType(char const *)" (?GetIdType@@YA?AUIdEntry@@PBD@Z)

Function GetIdType :

@IdEntry GetIdType(LPCTSTR Id)
{
IdEntry Entry;

Entry.InstanceId = FALSE;
Entry.Wild = NULL;
Entry.String = Id;

if(Entry.String[0] == INSTANCEID_PREFIX_CHAR)

{
Entry.InstanceId = TRUE;
Entry.String = CharNext(Entry.String); //-- Function causing the error!
}
if(Entry.String[0] == QUOTE_PREFIX_CHAR)
{
Entry.String = CharNext(Entry.String);
}
else
{
Entry.Wild = _tcschr(Entry.String,WILD_CHAR);
}
return Entry;
}@

Define CharNext:

@WINUSERAPI
LPSTR
WINAPI
CharNextA(
__in LPCSTR lpsz);
WINUSERAPI
LPWSTR
WINAPI
CharNextW(
__in LPCWSTR lpsz);
#ifdef UNICODE
#define CharNext CharNextW
#else
#define CharNext CharNextA
#endif // !UNICODE@

Error seems to be related to User32.dll, haven't found where to put this file yet...
Thanks

NicuPopescu

as I told you, you need in LIBS also user32.lib, no need to take care where is User32.dll : as other sys dlls it is in Windows system directory (i.e. C:\Windows\system32 on XP) which is one of the searched path for a required dll

maximus

I added User32.lib in the .pro of DEMO_LIB project (if I add it to ANT_LIB, DEMO_LIB would not build, possible to bundle a lib inside a static lib?)

How can I find all the lib dependency of project ANT_LIB? I have checked inside the visual studio project file, and couldn't find anything related to User32.lib

I now get a new error :
ANT_LIB.lib(WinDevice.obj):-1: error: LNK2019: unresolved external symbol imp__RegQueryValueExA@24 referenced in function "char * * cdecl GetRegMultiSz(struct HKEY *,char const *)" (?GetRegMultiSz@@YAPAPADPAUHKEY@@PBD@Z)

you need Advapi32.lib

this the comand line for linker in DEMO_LIB:

/OUT:"D:\Coolstream\Qt\Studiu\ANT\ANT_Windows_Library_Package_v3.2\Debug\DEMO_LIB.exe" /INCREMENTAL /NOLOGO /LIBPATH:"D:\Coolstream\Qt\Studiu\ANT\ANT_Windows_Library_Package_v3.2\Debug" "ANT_LIB.lib" "kernel32.lib" "user32.lib" "gdi32.lib" "winspool.lib" "comdlg32.lib" "advapi32.lib" "shell32.lib" "ole32.lib" "oleaut32.lib" "uuid.lib" "odbc32.lib" "odbccp32.lib" "D:\Coolstream\Qt\Studiu\ANT\ANT_Windows_Library_Package_v3.2\Debug\ANT_Lib.lib" /MANIFEST /ManifestFile:"Debug\DEMO_LIB.exe.intermediate.manifest" /ALLOWISOLATION /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /DEBUG /PDB:"D:\Coolstream\Qt\Studiu\ANT\ANT_Windows_Library_Package_v3.2\Debug\DEMO_LIB.pdb" /SUBSYSTEM:CONSOLE /PGD:"D:\Coolstream\Qt\Studiu\ANT\ANT_Windows_Library_Package_v3.2\Debug\DEMO_LIB.pgd" /TLBID:1 /DYNAMICBASE /NXCOMPAT /MACHINE:X86 /ERRORREPORT:QUEUE

see in LIBPATH how many .lib it seems needed

Thanks Nicu, finally the demo is working!!
I used Dependecy Walker and found that DEMO_LIB.exe uses KERNEL32.DLL, USER32.DLL, ADVAPI32.DLL, MSVCP120D.DLL and MSVCR120D.DLL

I Just added Advapi32.lib, should I add the others also?

Here is my working DEMO_LIB.pro file:
@TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt

HEADERS += demo.h

LIBS += "C:\Program Files (x86)\Windows Kits\8.1\Lib\winv6.3\um\x86\AdvAPI32.Lib"@

I will not have to ship these 2 libs with my application right? as all the windows system have it?
Thank you a million time!

NicuPopescu

congrats! :)

normally you don't need to deploy those dlls

you missed my suggestion to use only once LIBS+= all libs space separated

or

LIBS+= lib1
lib2
...
