gdbserver >= 7.2 comes with an optional library to use tracepoints,
|
|
the In Process Agent (IPA) library, libinproctrace.so. This library
|
|
uses some GNU extensions from the C library.
|
|
|
|
Say 'y' if you intend 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...

In case you have trouble with dynamic loading of shared libraries,
|
|
you will find that a static gdb comes in handy.
|
|
|
|
However, it has been noticed at least on x86 that enabling this
|
|
option produces an invalid gdb 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 binaries work.
