+builds, such as the EdkNt32Pkg, will not compile with gcc. By default, the edk2\r
+will try to build the NT32.fpd, which is not supported by gcc. So, you need to\r
+change the Tools/Conf/target.txt.\r
+\r
+The cross-compile build script has been tested on Cygwin, OS X and Linux. You\r
+should expect to hack on these scripts to make them work on your system. You\r
+may need to install additional tools on your system to make the scripts work.\r
+\r
+You will need\r
+\r
+ A recent version (3.0 or later should be fine) of gcc that is able to produce\r
+ executables for the machine that you want to run this compiler on (the host\r
+ machine).\r
+ wget or curl (which enables the download of the gcc compiler source code)\r
+ tar\r
+ bzip\r
+ gzip\r
+ bash\r
+ and possibly others\r

+CYGWIN Notes\r
+\r
+You should setup cygwin to use binmode on all mounts. When you initially\r
+install cygwin it gives you the choice of Unix file mode (recommended) or DOS\r
+file mode. Unix mode will cause all the cygwin directories to be mounted in\r
+binmode, while DOS will mount the dirs in textmode. Here is an example of a\r
+cygwin install where the dirs are (properly) mounted in binmode.\r
+\r
+C:\cygwin\bin on /usr/bin type user (binmode)\r
+C:\cygwin\lib on /usr/lib type user (binmode)\r
+c:\workspace on /workspace type system (binmode)\r
+C:\cygwin on / type user (binmode)\r
+\r
+If you use textmode, it is likely that the build will fail in a way that is\r
+hard to debug.\r
+\r
+Cygwin is pretty slow, so it is not recommended for large builds.\r
+\r
+\r
+\r
+\r
+\r
+The platform to be built is identified by the Tools/Conf/target.txt file:\r
+\r
+#\r
+# PROPERTY Type Use Description\r
+# ---------------- -------- -------- -----------------------------------------------------------\r
+# ACTIVE_PLATFORM Filename Recommended Specify the WORKSPACE relative Path and Filename \r
+# of the platform FPD file that will be used for the build\r
+# This line is required if and only if the current working\r
+# directory does not contain one or more FPD files.\r
+\r
+ACTIVE_PLATFORM =\r
+ \r
+You can leave it black, as above, or set it to any .fpd file in the workspace.\r
+If you leave it blank, then you just cd to the dir that contains the .fpd that\r
+you would like to build (MdePkg/ or EdkModulePkg/) and then type build.\r
