Hello
When building HC08 or HC12 application, you can redirect error messages to a file using the option
-EnvERRORFILE.
In order to automate the build of several project you can create a main project and add the projects you want to build as sub-project from this project.
.
Take a look at {Install}\Help\PDF\8_16bit_IDE_Users_Guide.pdf chapter "Projects", section "Working with Projects" -> "Managing Projects" -> "Subprojects" for information on how to achieve that.
