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.
