| Location of downloaded packages |
| =============================== |
| |
| It might be useful to know that the various tarballs that are |
| downloaded by the Makefiles are all stored in the +DL_DIR+ which by |
| default is the +dl+ directory. It's useful, for example, if you want |
| to keep a complete version of Buildroot which is known to be working |
| with the associated tarballs. This will allow you to regenerate the |
| toolchain and the target filesystem with exactly the same versions. |
| |
| If you maintain several Buildroot trees, it might be better to have a |
| shared download location. This can be accessed by creating a symbolic |
| link from the +dl+ directory to the shared download location: |
| |
| ----------------- |
| $ ln -s <shared download location> dl |
| ----------------- |
| |
| Another way of accessing a shared download location is to create the |
| +BUILDROOT_DL_DIR+ environment variable. If this is set, then the |
| value of DL_DIR in the project is overridden. The following line |
| should be added to +<~/.bashrc>+. |
| |
| ----------------- |
| $ export BUILDROOT_DL_DIR <shared download location> |
| ----------------- |
