CCS: CCS: specify compiler in projectspec

Nico,

You mentioned projectspec in the title. Are you using projectspecs? These are really templates that are used to generate projects. i.e. you import a project spec and CCS will then create the full project. It is possible to specify the compiler version in the projectspec and there are command line APIs for then importing/creating the project. However I suspect that you have a full project and just want to build that.

One approach would be to have different project configurations. Each configuration can specify the compiler version to use. You could then use command line to build specific configurations. processors.wiki.ti.com/.../Create

If you want to edit the project files the information is stored in the .ccsproject and .cproject files. We generally do not recommend editing these files directly as their formats are not public interfaces and can change between versions. The .cproject is really the one that would have to be changed.

The filed that contains the version looks like this:
<option id="com.ti.ccstudio.buildDefinitions.core.OPT_CODEGEN_VERSION.297475778" superClass="com.ti.ccstudio.buildDefinitions.core.OPT_CODEGEN_VERSION" value="17.9.0.STS" valueType="string"/>

However there are a lot of references to using the 17.9 build definitions throughout the file. I tried just changing that filed but then the option to build my project was disabled. So you would have to change all the references. In short I would not recommend doing it this way.

What sort of compiler change did you want to do? Was it changing from a 16.9.5 LTS to a 16.9.6 LTS or something more substantial? If it was minor then I would expect the first change to be enough as the build definitions themselves would still be ok.

Regards,
John

Thanks for your quick answer John.

I am doing quite a major compiler change. (5.2.6 vs. 16.9.1.LTS)

I am using projectspecs, but they don't seem to have an option to set the compiler?

I would be fine with different project configurations, but haven't figured out how the project configuration defines the compiler. Where do I append what?
