Building/linking with libstdc++ debug symbols?

[shabble]

When building a c++ application (targetting an STM32F746) using arm-none-eabi-gcc from the xpack 10.3.1-2.3.1, it links to the libstdc++.a archive inside the package, and runs correctly.

The problem arises when attaching gdb, when examining some std::stringstream instances, they are reported as <incomplete type> which is apparently (partly?) related to not having debug symbols for the stdc++ lib.

I haven't yet found a way to determine if the symbols are in the package (in the abovementioned .a archive, or elsewhere) somewhere and there's some way to activate them, or if I would need to rebuild the whole libstdc++ with different flags, and if so, how to actually do that 😄

Any suggestions/pointers?

Due to archive size constraints, the debug info is stripped from the released libraries.

I don't know of any simple trick to overcome this. You can try to bring the desired source files into your project and compile them together with the project.
