Using DCRABBIT\_9.62

1. Invoking dccl\_cmp.exe under windows 10 to build main.c results in no errors or binary.
2. The same project builds successfully under windows 7, producing a binary.

We are migrating our build from windows 7 to windows 10 due to EOL and security concerns.

What are our options?

I tried invoking the following command on Windows 10 and it successfully created pong.bin for a targetless option:  
“dccl\_cmp pong.c -rf MyTCparameters.rti” (Targeless option)

With target attached.  
“dccl\_cmp -pf myproject.dcp main.c” (Target attached)

I use Dynamic C 9 under Windows 10 regularly, including the command-line compiler.

Do you have the same project settings as on the Windows 7 machine? Directory layout? LIB.DIR contents?

If you just run dccl\_cmp.exe without parameters, do you see the usage instructions? If not, it could be Windows 10 blocking the application for some reason.

What are you using in your command line?
