Instead of having BR2_GCC_CROSS_CXX and BR2_INSTALL_LIBSTDCPP, with BR2_GCC_CROSS_CXX not being visible (and therefore being useless), let's just keep BR2_INSTALL_LIBSTDCPP to enable C++ in the toolchain and install C++ libraries on the target. We also take that opportunity to make BR2_INSTALL_LIBSTDCPP an hidden option, which is selected by an option in Buildroot toolchain support or an option in External toolchain support, just as we did for other toolchain features. Some work definitely remains to be done : - The name BR2_INSTALL_LIBSTDCPP is ugly, but we keep it for the moment in order to avoid changing all packages. - We should clarify the other language-related options (Fortran, Java, Objective-C, etc.).

Setting this option will enable the "-mfpu=vfp" option.

If your ARM CPU has a Vector Floating Point Unit (VFP)

and the toolchain supports the option, then the

code can be optimized.

help
|

When using buildroot to build a deployable cross toolchain,
|
|
it is handy to include certain target apps with that toolchain
|
|
as a convenience.
|
|
Examples include ldd, gdbserver, and strace.
|
|
|
|
Answer Y if you want these apps (if built) copied into the
|
|
cross toolchain dir under <arch>-linux-uclibc/target_utils/.
