Currently, the PE/COFF conversion routines in GenFw add a so-called
NB10 CodeView debug record to the image, and update the associated
directory entry in the PE/COFF optional header to contain its relative
virtual address (RVA) and size.
However, there are two levels of indirection at work here: the actual
NB10 CodeView record (which is simply a magic number and some unused
data fields followed by the NUL terminated filename) is emitted
separately, and a separate descriptor is emitted that identifies the
NB10 CodeView record as type EFI_IMAGE_DEBUG_TYPE_CODEVIEW, and records
its size. The directory entry in the PE/COFF optional header should
refer to this intermediate descriptor's address and size only, but
the WriteDebug## () routines in GenFw erroneously record the size of
both the descriptor and the NB10 CodeView record.
This problem was exposed by commit e4129b0e5897 ("BaseTools: Update
GenFw to clear unused debug entry generated by VS tool chain",
2017-06-19), and GenFw now crashes when it attempts to iterate over
what it thinks are multiple intermediate descriptors for different
kinds of debug data embedded in the image.
The error is understandable, given that both are carved out of the
same file space allocation, but this is really an implementation detail
of GenFw, and is not required. (Note that the intermediate descriptor
does not require a RVA and so it does not even need to be inside a
section)
So omit the size of the NB10 CodeView record from the size recorded
in the optional header.

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 from your preferred Visual Studio installation or you can run get_vsvars.bat to use latest automatically detected version. 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
