| Location of downloaded packages |
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
| |
| The various tarballs that are downloaded by Buildroot are all stored in |
| +DL_DIR+, which by default is the +dl+ directory. If you want |
| to keep a complete version of Buildroot which is known to be working |
| with the associated tarballs, you can make a copy of this directory. |
| 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> |
| ----------------- |
| |
| The download location can also be set in the +.config+ file, with the |
| +BR2_DL_DIR+ option. This value is overridden by the +BUILDROOT_DL_DIR+ |
| environment variable. |
