| Subject: [PATCH] fix issues with gdb 8.0 |
| |
| GDB 8.0 is compiled and linked with g++, but the |
| linking of static targets (f.e. coldfire) fails, |
| without declaring the functions in thread_db.h |
| extern C. |
| |
| The compilation of gdb errors out with: |
| thread-db.o: In function `thread_db_init()': |
| thread-db.c:(.text+0x5b6): undefined reference to `td_ta_new(ps_prochandle*, td_thragent**)' |
| thread-db.c:(.text+0x61e): undefined reference to `td_thr_get_info(td_thrhandle const*, td_thrinfo*)' |
| thread-db.c:(.text+0x632): undefined reference to `td_symbol_list()' |
| .. |
