Approximately required disc space for compiling OpenWrt:
|Stable Source||1.5 GB||3.5 GB|
|all feeds/pkgs||>30 GB|
Build-time is highly dependable on the number of Cores/Jobs and can be shrunk to less than 30 minutes (from 90 minutes). (make -j 4)
Yes, of course. If you find any bugs, please use our ticket system or send a report to email@example.com . You can send patches for the bugs as well.
/!\ NOTE: Changes to the buildroot system or the associated
Makefilescould break the compile process. Please do not submit bug reports against modified copies of buildroot. Thanks!
See Creating Packages.
The OpenWrt build bots provide a list of broken packages: http://buildbot.openwrt.org:8010/broken_packages/
There is a comparison of OpenWrt and upstream package versions available: https://home.comcast.net/~sdwalker/uscan/index.html
The mailing list: https://lists.openwrt.org/pipermail/openwrt-devel/ generates Patchwork entries: http://patchwork.openwrt.org/
- Use -j switch to enable parallel builds
- Use local mirror to avoid downloads (advanced build options)
- Files inside the buildroot are specific to host systems.
Build dependency: Please install GNU find # old files in staging_dir/host
- remove untracked files with the help of svn or git
- use make targets depending on what you don't want
make clean make dirclean make distclean make target/linux/clean * rm -rf tmp/ rm .config .config.old* Kernel Config change is not triggering rebuild, see: openwrt-devel
If you are running a buildroot inside a VM with many threads you might experience random build failures.
Setup: Host: i7 16GB RAM, VM on Harddisk, Win 7 64bit, VMWare Player Guest: Lubuntu 13.04 64bit 4GB RAM ext4 partition make -j 8
Errors: Build fails like
mv: cannot stat '.deps/dlog.Tpo': No such file or directory or ../libtool: line 46: -c: command not found libtool: Version mismatch error. This is libtool 2.4, but the libtool: definition of this LT_INIT comes from libtool 2.2.6. libtool: You should recreate aclocal.m4 with macros from libtool 2.4 libtool: and run autoconf again.cleaning up buildroot helps sometimes, reduce concurrency
