How to migrate new software packages to your own openwrt system? Let's continue reading.
- After openWRT is compiled, the following files will be generated:
and the directory staging_dir will be used as the temporary installation directory for compilation, and the final generated files will be saved in the directory bin
| table of Contents | meaning |
|---|---|
| dl | Download the temporary directory of the software code package. Before compiling, download the original software code package to this directory |
| feeds | Extension package directory. Put some infrequently used software packages in other code bases, and customize download and configuration through the feed mechanism |
| bin | The final result catalog after compilation. Such as installation image file and ipk installation package |
| build_dir | Compile the intermediate file directory. |
| staging_dir | Compile the installation directory. The files are installed here, and the final compilation results are generated from the files here |
| tmp | A large number of temporary files during the compilation process will be here |
- The feeds directory The feeds directory is
used to store the extension software package. You can use the package compilation extension mechanism for extension installation.
Steps to transplant a new software package:
(1). Put the software package to be migrated into the corresponding location under the feeds folder according to the package category. Establish a soft link to the corresponding location in the package directory of the main compilation directory.
$ cd package/feeds/routing
$ ln -s ../../feeds/routing/frr ./ #相对位置待移植的 FRR
(2). After executing ./sripts/feeds install -a, the transplanted new software package will be displayed in the menuconfig configuration menu.
$ cd ../../
$ make menuconfig
3. dl directory
compiler tool chain, the target platform and other software packages need to download the files are placed dl directory
during compilation, all kinds need to download the packages are stored in this directory (the tool used in the compilation process)
when During the compilation process.
If an error occurs , the cause of the error is that a certain software package is downloaded incorrectly or is missing, you can manually download the corresponding software package (compressed file), and place it in this directory, and then recompile.
- build_dir directory
Compilation intermediate file directory of the cross-compilation tool and the result file of the target platform compilation.
Such as: image, rootfs, uboot, dtb and other compilation results;
after successful compilation, the script packaging results will be executed and copied to the bin/target folder.
5. The staging_dir directory is
used as a temporary installation directory for compilation. The content is as follows: The
version of the libyang library in OpenWRT-19.07 is low, and the version that FRR depends on is 1.0.184, so you need to install the PKG_VERSION:=1.0.184 libyang library, delete package/feeds Copy the Makefil file of libyang-1.0.184 to this directory for the contents under the /packages/libyang folder, and recompile the OpenWRT feeds package management tool to automatically download this version of the library file.
