[edk2] regarding the chapter 4 sample program in the book Beyond Bios

2014-01-30 Thread John Davis 
Hello

I'm reading the Beyond Bios book in conjunction with the stuff on
tianocore.  The example code in chapter 4 of that book talks about a
HelloApplication.  The format looks different from the sample code in
AppPkg\Hello directory of the EDK2 src.  Is that format/api shown in the
book obsolete?  The book does not say how to compile it or even where to
put it and I am confused.

Re: [edk2] regarding the chapter 4 sample program in the book Beyond Bios

2014-01-30 Thread Jarlstrom, Laurie 
The Hello in the AppPkg\Applications\Hello\ uses the “Print” function that is 
part of the UefiLib Library. While the Helloworld.c in the Beyond BIOS book is 
making a call using the EFI_SERVICES SystemTable pointer that is passed into 
its entry point.
Both are correct and both are current.

For writing and compiling look at the links for 
http://sourceforge.net/apps/mediawiki/tianocore/index.php?title=Getting_Started_with_EDK_II
This show how to compile EDK II in several OS/Compiler environments

For another example:

I’m guessing the one in the book looks more like: 
https://svn.code.sf.net/p/edk2/code/trunk/edk2/MdeModulePkg/Application/HelloWorld/HelloWorld.c
This is a the generic UEFI Application/Driver entry point. 

The application in the AppPkg depends on the shell. So these are not UEFI 
applications, they are UEFI shell applications. They depend on the shell being 
loaded to function. 

I think you will find that the entry point for the UefisShellCEntryLib is the 
same as a UEFI Application. This library looks up info from a protocol produced 
by the shell to figure out the arguments.

Hello Laurie,

Thank you for letting me know the source is still valid.  I'll look at the
references you provided to see if I can get it working. I do have that
massive 400+ page pdf and I have built the emulator.  It just takes a while
to dig though.  It seems the answer is in there, I just haven't found it
yet.

Thank you

Yeah, I don't think this code will build. I understand what you guys were
telling me about it being a higher abstraction. Kind of like programming in
Xt versus programming in Motif but when I try to massage it into building
it does not work.  It complains about not being able to find efi.h.  I did
a search on efi.h the ones I found are commented out of the Nt32Pkg build
file.

I give, I'll move on.

efi.h implies the EDK project, not the edk2. It would be Uefi.h for edk2.

Re: [edk2] regarding the chapter 4 sample program in the book Beyond Bios

2014-01-30 Thread John Davis 
Hello

I got it working.  Thanks for the help.  I used the code from the book with
the uefi.h include and I modeled the .inf file from the samplehelloapp in
the edk2.  The only problem was using the webpage to generate the guid.  I
don't know if that line was meant to generate a guid or simply use that
site to generate one.  I just wrote a random one.  If I used the webpage in
the file as is, it crashes the build.

Thanks again

John
