Hello Andrew,
Thanks, I appreciate the pointer.
FWIW, I have also learned based upon Bill Pauls previous Moo code sample,
you don't need to put apps in packages. I was using the
MdeModulePkg/Application/HelloWorld/ directory as a source. I got tired of
having to stop the emulator each time I made a change to my code in order
for it to build. Consquently, I learned you can do this:
1. Create you app at top level directory.
ex. MyFindRom2/MyFindRom2.inf and .c
2. Add the .inf to Nt32Pkg/Nt32Pkg.dsc
3. Build all
4. Build run
5. Run app via MyFindRom2
6. Make change to app
7. Build app via > build -m MyFindRom2\MyFindRom2.inf
8. return to emulator and run the new app without having to shutdown the
emulator.
Bill was building a completely new package with a .dsc. I am just building
a component using a .inf. I believe it was you who told me previously
about the contents of a .fdf and .dsc file.
Thanks again
John
