How to define a pre-build step from a batch file in CCS4

mdalik

I'm in the process of migrating a project from CCS3.3 to CCS4.2 and I'm stymied with the right way to define pre-build steps.

In CCS3.3, I could do something like this

.\create.bat

as a pre-build step on the Build Options dialog box and it would run at every build to create a .h file for me that would then get compiled into my code. Because of the relative path, anyone could use the batch file; we would commit it into Subversion at the top level of our project tree and everyone was happy. CCS would find the file and run it before building anything.

The purpose of the script was to create a timestamp that would get built into the binary, which we could then query at runtime, so we knew when the binary was actually built.

I'm not able to do this in CCS4, when I try to build I get "The system cannot find the file specified." apparently from a call to CreateProcess().

How do I specify an external pre-build command with a relative path that will execute on every build. Is there any reference to how CCS4 is executing these commands?

Thanks! Erik

Erik,

You may need to use a variable to do this. i.e. you would have something ${workspace_loc}\create.bat

Where is create.bat relative to the project? In the root of the project dir?

John

Thanks for the quick answer, John.

The batch file is indeed in the root of the project directory. I did not copy the files into the workspace, because that seemed to give me trouble with setting up a Subversion working copy. So when I tried

${workspace_loc}/create.bat

I still received the "cannot find file" error. Is there another variable for the project directory vs. the workspace directory?

I found that ${PROJECT_ROOT} gets me where I want to be, but now I need to find out how to make that directory the current working directory. So I'm making progress.

Could you also pass ${PROJECT_ROOT} to the batch file as a parameter and then in the batch file set the current windows directory to that value?

Thanks John, I got it to work. FInding ${PROJECT_ROOT} and then remembering how to pass arguments to a .BAT file got me to the solution. Erik
