27.1. build-userland
Build userland programs.
Build all with:
./build-userland
or build only those under e.g. userland/c with:
./build-userland userland/c
The executables are not automatically added to the Buildroot image, you must follow the command with a ./build-buildroot command as in:
./build-userland ./build-buildroot
Remember that certain executables have specific requirements, e.g.:
-
userland/arch/ programs only build if the target arch matches
-
userland/libs directory require the
--packageoption userland/libs directory
Default: build all examples that have their package dependencies met, e.g.:
-
an OpenBLAS example can only be built if the target root filesystem has the OpenBLAS libraries and headers installed, which you must inform with --package
