As Jordan mentioned, one must add the statement
!include StdLib/StdLib.inc
to their .dsc file. This will cause the necessary Library Classes to be
defined as well as setting up the build options needed for StdLib based
applications. This should go at the end of the .dsc file.
The ReadMe.txt file lists the dependencies between header files and libraries.
If all necessary libraries are not listed in the application's .inf file, you
will get unresolved external errors since the required libraries will not be
searched.
The .dsc files in both AppPkg and StdLib have been designed as examples to be
used for deriving files for your own packages. Read the comments.
The .inf files from the sample applications in AppPkg can be used as examples.
The "Main" application is the simplest application and "Python" is the most
complex. Other than the number of source files, though, there isn't much
difference between the .inf files for "Main" and "Python".
For experimentation, it is easiest to start by modifying the "Main" application
within AppPkg. This way you are starting with something that works so that you
minimize the number of unknowns.

Subject: Re: [edk2] Entry Point While Using int main (argc, **argv)
Hii Justen,
Thanks for the help. I was able to resolve that issue.
However,now all the functions from StdLibPkg (fopen,fclose etc.) are now being
shown as unresolved externals (error LNK2001)
My .inf file has StdLib/StdLib.dec included in the [Packages.common] Section.
Could you tell me how to get around this problem??
Regards,
Nishit Patira

I don't think Nishit needs to use AppPkg.dsc. More likely a separate
.dsc will be used, but you'd want to refer to:
AppPkg/ReadMe.txt =>
BUILD CONFIGURATION => DSC Files =>
"!include StdLib/StdLib.inc"
To configure the new .dsc for StdLib usage.
