I added the two missing files to the project through the IDE and was able to compile successfully. The compilation was pretty quick, considering that I was running on a laptop. I was left with a couple of problems:
1. The program only ran if I clicked on Run from the menu in the IDE. If I tried to run lyx.exe directly, nothing happened (including nothing printed to the console). 2. Whenever I exited the program there was a fatal error (something about file unlocking, I think). Unfortunately, the next morning, my NTFS became corrupt and my entire source directory disappeared (along with quite a few more important documents). If you would like to recreate what I did, download the free Visual C++ 2005 Express Edition from the Microsoft website. MSVC converts the .vcproj files and .sln file to the newer format. I was writing up a detailed list of the steps I took as I went along but that is also lost. I may try again after I get my drive back from my IT department, which is now attempting recovery.
