It still complains about _aeabi_unwind_cpp_pr1. If I use only -lgcc, the linker complains about both "_aeabi_unwind_cpp_pr1" "__cxa_end_cleanup" as well as "memset". I added the -lc option to get rid of the "memset" undefined reference error. I've written custom functions to override the standard gcc functions like strcmp, strcpy, free, malloc etc. The env the binary will run in will not have the standard libraries available. > > __cxa_end_cleanup is normally defined lib libsupc++.

When I add this option, it complains about many more standard symbols: strlen, free, malloc, __aeabi_unwind_cpp_pr0, __cxa_pure_virtual etc. JJ
