Thanks Xiang - that got me to the linking step! I'm getting this error: make[2]: Leaving directory '/nuttx/nuttx_patch/nuttx/boards/arm/stm32/common' LD: nuttx arm-none-eabi-ld: /tools/gcc-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/lib/thumb/v7-m/nofp//libsupc++.a(vterminate.o): in function `__gnu_cxx::__verbose_terminate_handler()': vterminate.cc:(.text._ZN9__gnu_cxx27__verbose_terminate_handlerEv+0xf4): undefined reference to `_impure_ptr' make[1]: *** [Makefile:172: nuttx] Error 1 make[1]: Leaving directory '/nuttx/nuttx_patch/nuttx/arch/arm/src' make: *** [tools/Makefile.unix:401: nuttx] Error 2
I tried the hack going around about using this to overwrite vterminate.cc for the uclib library: arm-none-eabi-ar -x libsupc++.a vterminate.o I was able to generate vterminate.o in that way but the "hack" mentions overwriting an existing vterminate.o. I can't find vterminate.o anywhere else in the project. Probably doesn't matter, but here's the part of a map generated with LDFLAGS where it references the _impure_ptr ... _exit /nuttx/nuttx_patch/nuttx/staging/libsched.a(exit.o) /nuttx/nuttx_patch/nuttx/staging/libsched.a(pthread_exit.o) _impure_ptr /tools/gcc-arm-none-eabi/bin/../lib/gcc/arm-none-eabi/9.2.1/../../../../arm-none-eabi/lib/thumb/v7-m/nofp//libsupc++.a(vterminate.o) _sbss /nuttx/nuttx_patch/nuttx/staging/libarch.a(stm32_start.o) ...
