hi,
i have a .mak file while has four depencies(libraries- libgroupsock.lib, libusageenvironment.lib,libbasicusageenv.lib and liblivemedia.lib)
but on building the .mak file , i am facing the following problem.
how to resolve this error.
if the libraries are to be added , how and where to add them..?
kindly help me.
libgroupsock.lib(Groupsock.obj) : error LNK2001: unresolved external symbol _security_cookie
|
|
|
|
|
Probably you will must determinate
what library does provide the function(?) security_cookie
and then include its usage... 
virtual void BeHappy() = 0;
|
|
|
|
|
by "include in usage" waht do u mean ?
just add the path in the include files?
|
|
|
|
|
kindly help me. i am doing a project regarding rtsp client and i am a new bie to VC 6.0
|
|
|
|
|
No, include the lib of the unresolved symbol to the linking process.
It could be perform in a .cpp file as following too :
#pragma comment(lib, "NameOfLibOfUnresolvedSymbol.lib")
virtual void BeHappy() = 0;
|
|
|
|
|
oh thanks a lot.
but mine is a .mak file . while building it i am facing such errors.
how to link the libraries to the .mak file? any commands available?
|
|
|
|
|
Probably you could extend your line by the needed lib :
libraries- libgroupsock.lib, libusageenvironment.lib,libbasicusageenv.lib and liblivemedia.lib, NEEDED.lib
virtual void BeHappy() = 0;
|
|
|
|
|
Please observe
how to include some libraries to the link process :
CC= cl
#DEFS= -nologo -DSTRICT -G3 -Ow -W3 -Zp -Tp
DEFS= -nologo -G3
PROGNAME= foo.exe
LINKER=link -nologo
INCLUDES= -I.
# don't define -DSYS_WIN32.. win2k complains
DEFINES= $(INCLUDES) $(DEFS) -DWINNT=1
CFLAGS= $(DEFINES)
GUIFLAGS=user32.lib gdi32.lib winmm.lib comdlg32.lib comctl32.lib
WINSOCK_LIB=wsock32.lib
LIBS=$(WINSOCK_LIB) $(GUIFLAGS)
RC=rc
RCVARS=-r -DWIN32
SRCS = foo.c main.c
OBJS = foo.obj main.obj
.c.obj:
$(CC) $(CFLAGS) -c $< -Fo$@
all: $(PROGNAME)
$(PROGNAME) : $(OBJS)
$(LINKER) $(OBJS) /OUT:$(PROGNAME) $(LIBS)
clean:
del $(OBJS) $(PROGNAME) core
virtual void BeHappy() = 0;

ya got it. but in my make file there is not option for including the libraries. well i paste my makefile here.it is still giving the same errors

hi ,
thanks for ur patient replies
LINK_OPTS_0 = $(linkdebug) msvcrt.lib libBasicUsageEnvironment.lib libgroupsock.lib libliveMedia.lib libUsageEnvironment.lib
i have added the libraries like this.
now after i compiled , good news is erros got reduced. but new ones have popped in.

Please try this suggestion firstly :
LINK_OPTS_0 = $(linkdebug) msvcrt.lib bufferoverflowU.lib

oops sorry buddy.
i added the bufferoverflowU.lib and have got the following error.
LINK : fatal error LNK1181: cannot open input file "bufferoverflowU.lib"

OK
Please try to find the bufferoverflowU.lib file
on your (probably C:\ ) harddisk and set it with its full path,
please, for a test only. Thanks

Do you compile for x64 ?
Please remove all additional libs
and try to set the only "full pathed" msvcrt.lib
from your x64 SDK directory

hi,
i will tell what i need exactly.
i have .mak file called testprogs.mak.
this has to be linked to four .lib files.
the problem is how should i first build a make file. what i do is
openworkspace -> .mak file -> ok
vc 6.0 by default creates a workspace.
now the item opened in just a make file and not a project, so i am not able to link the .lib files. and finally getting many errors.
kindly help me

What part of "The project is missing a reference to a library (.LIB) or object (.OBJ) file" are you not understanding? Did you read the .lib Files as Linker Input link?

Why would you do that? Libraries and include/header files are not the same thing.
If you are using VS6, click the Directories tab of the Tools->Options dialog. In the Show directories for: combobox, select Library files. Add the name of the folder that contains the .lib file you are using. Click the Link tab of the Project->Settings dialog. In the Category combobox, select Input. In the Object/library modules: edit control, add the name of the .lib file you are using.

hi ,
i already tried to include the libraries in the Directories tab of the Tools->Options dialog.
but that didnt solve the problem .
i opened a .mak file in the workspace, its not a project. so in its settings in dont have an option for link the .lib files .
how should i build a .mak file which has to be linked to few of the libraries.
