==== Location of downloaded packages
|
||
|
|
|
||
|
|
The various tarballs that are downloaded by Buildroot are all stored
|
||
|
|
in +BR2_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 achieved by pointing the
|
||
|
|
+BR2_DL_DIR+ environment variable to a directory. If this is
|
||
|
|
set, then the value of +BR2_DL_DIR+ in the Buildroot configuration is
|
||
|
|
overridden. The following line should be added to +<~/.bashrc>+.
|
||
|
|
|
||
|
|
-----------------
|
||
|
|
export BR2_DL_DIR=<shared download location>
|
||
|
|
-----------------
|
||
|
|
|
||
|
|
The download location can also be set in the +.config+ file, with the
|
||
|
|
+BR2_DL_DIR+ option. Unlike most options in the .config file, this value
|
||
|
|
is overridden by the +BR2_DL_DIR+ environment variable.
