Up until SVN r18540, GenFw created invalid PE/COFF binaries for the ARM architecture, by allowing PE/COFF .data sections to appear at offsets that were not aligned to the global PE/COFF section alignment. The reason for this was that the relocation metadata emitted by RVCT's armlink only contains dynamic absolute relocations, so it is impossible to recalculate relative relocations between .text and .data, and so the relative offset between the two needs to be preserved. Since r18540, we do align .data to the PE/COFF section alignment, resulting in potentially corrupt PE/COFF binaries unless .data happens to appear at a 32-byte aligned offset. So let's introduce a RVCT scatter file that sets this alignment for the ELF .data section (and subsequent .bss section). At the same time, set the start offset to 0x220 bytes (which is the size of our 32-bit PE/COFF header) so that the memory layouts are identical between ELF and PE/COFF. Also add a 4 KB aligned version that can be used to build DXE_RUNTIME_DRIVER modules with runtime memory protection enabled.

This directory contains the next generation of EDK II build tools and template files. Templates are located in the Conf directory, while the tools executables for Microsoft Windows 32-bit Operating Systems are located in the Bin\Win32 directory, other directory contatins tools source. 1. Build step to generate the binary tools. === Windows/Visual Studio Notes === To build the BaseTools, you should run the standard vsvars32.bat script. In addition to this, you should set the following environment variables: * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree * BASE_TOOLS_PATH - The directory where the BaseTools source is located. (It is the same directory where this README.txt is located.) * PYTHON_FREEZER_PATH - Path to where the python freezer tool is installed After this, you can run the toolsetup.bat file, which is in the same directory as this file. It should setup the remainder of the environment, and build the tools if necessary. Please also refer to the 'BuildNotes.txt' file for more information on building under Windows. === Unix-like operating systems === To build on Unix-like operating systems, you only need to type 'make' in the base directory of the project. === Ubuntu Notes === On Ubuntu, the following command should install all the necessary build packages to build all the C BaseTools: sudo apt-get install build-essential uuid-dev === Python sqlite3 module === On Windows, the cx_freeze will not copy the sqlite3.dll to the frozen binary directory (the same directory as build.exe and GenFds.exe). Please copy it manually from <PythonHome>\DLLs. The Python distributed with most recent Linux will have sqlite3 module built in. If not, please install sqlit3 package separately. 26-OCT-2011
