Currently, uClic++ 0.2.5 fails to compile when using a long filepath. For example, if the openwrt directory is in the path: /tmp/this_directory_name_is_very_long/more_long_paths/.../openwrt, then uclibc++ will cause a very obtuse error. Although the uclibc++ makefiles do print a "File name too long" error, it's not the final error that's printed, so it's a bit confusing: > /bin/sh: 1: > cannot create src/abi/libsupc/<SNIP>_libsupc++.a.dep: File name too long > <SNIP: some other makefile output here> > array_type_info.o: No such file or directory Although OpenWRT 22.03 and current master branch have removed uClib++, I thought I'd make a PR for OpenWRT 21.02, since I encountered it and there seems to be quite a few other people experiencing the same issue. It especially happens when using the SDK, (or when using an encrypted fs) since the pre-packaged SDKs have very long filenames. This patch is already in upstream [1], but has not yet been released.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.
Sunshine!
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev rsync which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
Related Repositories
The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
