4.2 How to Rebuild TivaWare Libraries

There are a few situations where recompiling the library files to get a new .lib file output is necessary. One situation would be the case mentioned at the start of this chapter to enable debug of the library. A more common situation would be to change the optimization of the library in terms of speed / size trade-offs. A rare circumstance may be to reflect a change in library files where the .lib file is recompiled in order to reflect the modifications made. The risk with that approach over keeping the modified source file in the project is that it requires maintaining the library over time to ensure the updates are not lost across versions.

In order to recompile a TivaWare library, it must be imported into CCS and rebuilt. The same steps as outlined in Section 3.3 apply except for one key difference. The box ‘Copy projects into workspace’ must be unchecked. This keeps the library project and the build outputs located in the TivaWare folder to which all TivaWare projects are linked.

Once imported, simply rebuild the project and the changes will be applied in the new .lib file within the TivaWare directory.
