lnk2019 error - time and memory functions, which library?

NTDEV
1

Hi Guys,

I have a feeling this is a stupid mistake I am making on this driver, but I can’t find it and am hoping someone might have an idea.

I am finishing up a USB network driver and am having some issues linking it. I am obviously missing the right library to link to, but haven’t been able to find the right now. Any ideas? I am building for XP using the DDK for Server 2003.

My sources files is as follows:

TARGETNAME=myDriver

TARGETTYPE=DRIVER

DDKROOT=$(BASEDIR)

INCLUDES= $(DDK_INC_PATH); \
…\inc;

System and NDIS wrapper definitions.

C_DEFINES=-DNDIS_MINIPORT_DRIVER=1 -DNDIS_WDM=1

The driver is built in the XP or .NET build environment

So let us build NDIS 5.1 version.

C_DEFINES=$(C_DEFINES) -DNDIS50_MINIPORT=1 -DWMI_SUPPORT

TARGETLIBS=$(DDK_LIB_PATH)\ndis.lib \
$(DDK_LIB_PATH)\usbd.lib

KMDF_VERSION_MAJOR=1

NO_BINPLACE=1

SOURCES= \
wifimac.cpp \
hw_card.cpp \
…
Card.cpp

These are the link errors I am getting:

1>ntoskrnl.lib(ntoskrnl.exe) : error LNK2005: xxxxx@4 already defined in wdmutils.obj
1>hw_card.obj : error LNK2019: unresolved external symbol __imp__realloc referenced in function “int __stdcall cbQueryInformation(void *,unsigned long,void *,unsigned long,unsigned long *,unsigned long *)” (?cbQueryInformation@@YGHPAXK0KPAK1@Z)
1>mac_mgmt.obj : error LNK2001: unresolved external symbol __imp__realloc
1>mac_tkip.obj : error LNK2001: unresolved external symbol “unsigned long __stdcall GetTickCount(void)” (?GetTickCount@@YGKXZ)

1>mac_buf.obj : error LNK2019: unresolved external symbol __imp__malloc referenced in function “unsigned char __stdcall InitBuffers(void)” (?InitBuffers@@YGEXZ)
1>cardwiwave.obj : error LNK2001: unresolved external symbol __imp__malloc
1>mac_buf.obj : error LNK2019: unresolved external symbol __imp__free referenced in function “void __stdcall ReleaseBuffers(void)” (?ReleaseBuffers@@YGXXZ)
1>wdmutils.obj : error LNK2001: unresolved external symbol __imp__free

Any help would be hugely appreciated. If you need any more information, please let me know. Thanks, Val

I’m not sure how, but you’re linking with both wdm.lib & ntoskrnl.lib.

The other problem is that you seem to be using malloc()/free(). You don’t use these in a kernel driver. See ExAllocatePoolWithTag().

Good luck,

Finishing? Doubts, too many problems. As Martin said malloc/free. I’m
adding GetTickCount() which is Win32 function not available in kernel.
It seems as you’re compiling some user mode code to kernel driver which
is wrong.

Next problems:

  • sscanf – bad even in user mode.
  • C++ – asking for problems in kernel unless you exactly know what
    you’re doing
  • incorrect use of C functions in C++ code: GetTickCount@@YGKXZ which
    indicates above point isn’t fulfiled (seems you include user mode
    headers)

BTW, what is USB network driver?

An NDIS miniport with a USB lower edge?
