gdb arc-2016.09-rc1 is based on upstream 7.12 gdb version where we can still disable C++ build. For more information take a look at: https://sourceware.org/gdb/wiki/cxx-conversion We wanted to build gdb with C++ as it is used as default in 7.12 and is even a mandatory requirement since 2016/09. But unfortunately we missed one runtime failure that C++ build causes and so now we have to disable C++ build. When gdb arc-2016.09-rc1 is built as a C++ application it segfaults at runtime for ARC. We are going to fix the issue in 2017.03 ARC toolchain release. and before this we remove C++ dependency are adding temporary workaround to prevent runtime segfaults. The workaround is to disable building gdb as C++ application via passing --disable-build-with-cxx config option when building gdb for ARC.

GDB, the GNU Project debugger, allows you to see what is
|
|
going on `inside' another program while it executes -- or
|
|
what another program was doing at the moment it crashed.
|
|
|
|
This option allows to build gdbserver and/or the gdb
|
|
debugger for the target.
|
|
|
|
For embedded development, the most common solution is to
|
|
build only 'gdbserver' for the target, and use a cross-gdb
|
|
on the host. See BR2_PACKAGE_HOST_GDB in the Toolchain menu
|
|
to enable one. Notice that external toolchains often provide
|
|
their own pre-built cross-gdb and gdbserver binaries.
