GDB8 (or rather gnulib that is a part of it) provides a fallback mbstate_t definition - but GCC's C++ headers (which are used via stdint.h since GDB8 uses C++) provide another mbstate_t if libc does not have wide char support. These two definitions conflict with each other. Signed-off-by: Alexey Neyman <stilor@att.net>

In case you have trouble with dynamic loading of shared libraries,
|
|
you will find that a static gdbserver comes in handy.
|
|
|
|
However, it has been noticed at least on x86 that enabling this
|
|
option produces an invalid gdbserver binary. It is linked with
|
|
"-static -Wl,--dynamic-list=..." which
|
|
# (a) requests invalid program interpreter
|
|
# (b) crashes glibc/uClibc-ng and does not work with musl
|
|
# See https://sourceware.org/ml/libc-alpha/2017-03/msg00267.html
|
|
|
|
It is possible it would work with other architectures, hence it is
|
|
not completely removed. Use with care and report to the mailing list
|
|
if the resulting gdbserver works.

gdbserver >= 7.2 comes with an optional library to use tracepoints,
|
|
the In Process Agent (IPA) library, libinproctrace.so.
|
|
|
|
Say 'y' if you indend to use tracepoints when debugging your
|
|
programs with gdbserver.
|
|
|
|
Note: Currently, building this library is not possible when the
|
|
gdbserver is built statically. This is a limitation in
|
|
crosstool-NG, so do not bug upstream about it...
