Ard, I was trying to compile and generate helloworld application via EDK2.Under the "MyWorkSpace\BaseTools\Bin" directory I did not find "Win32" directory which has GenFw utility.But the UDK package has Win32 directory.
Could you let me know on how to build and EDK2 package in Windows or else Am I missing something here?
Thanks Ravi

Thanks.

Ard,
OK.But when a simple HelloWorld program,which is part of EDK2 sample programs and which is written in c,is renamed to .CPP,we get these relocation issues in-spite of not using any C++ runtime API's.
In UDK or EDK2?

Hi Ard,
Hope you remember we speaking about the 0x105 and 0x0 relocation
issues
which we came across while compiling a simple HelloWorld program in CPP.As you said on the other thread(EDK2 mailing list)we need some changes
to
compiler and GenFw utility of UDK,can we take the required changes forward and come up with a UDK with this support?
We are stuck at this juncture with this activity and would need your help badly.
Please forget about UDK, and rebase your work onto the latest EDK2 master branch. There have been many changes to the way relocations are handled, which also impose requirements at link time (i.e., in terms of section alignment, and relative offset between sections both in the ELF and the PE/COFF versions of the image)
However, the relocation issue was due to the fact that you were using the Linux version of the C++ runtime, which you cannot use under EDK2 even if we do support those relocation types with the newer tools.
Bottom line is that you need to develop your own C++ minimal runtime if you want to run C++ programs under EDK2
