Just saw that I should post these types of questions to the mailing list and cc David. If anyone can help, I'd really appreciate it. Thanks!

After downloading, compiling, and installing the libunwind library from git, I tried to compile tests/test-ptrace.c using the following command: cd tests gcc -I../include -lunwind-ptrace -lunwind-generic -lunwind -o test-ptrace test-ptrace.c The instructions here: http://www.nongnu.org/libunwind/man/libunwind- ptrace(3).html, indicates that's all it's to it. However, I'm getting the following compile error: /tmp/ccsrDTfR.o: In function `do_backtrace': test-ptrace.c:(.text+0x4b): undefined reference to `_Ux86_64_init_remote' test-ptrace.c:(.text+0xa3): undefined reference to `_Ux86_64_get_reg' test-ptrace.c:(.text+0xcd): undefined reference to `_Ux86_64_get_reg' test-ptrace.c:(.text+0x157): undefined reference to `_Ux86_64_get_proc_name' test-ptrace.c:(.text+0x215): undefined reference to `_Ux86_64_get_proc_info' test-ptrace.c:(.text+0x2ca): undefined reference to `_Ux86_64_step' test-ptrace.c:(.text+0x2f4): undefined reference to `_Ux86_64_get_reg' /tmp/ccsrDTfR.o: In function `main': test-ptrace.c:(.text+0x480): undefined reference to `_UPT_accessors' test-ptrace.c:(.text+0x485): undefined reference to `_Ux86_64_create_addr_space' test-ptrace.c:(.text+0x62b): undefined reference to `_Ux86_64_set_caching_policy' test-ptrace.c:(.text+0x7d5): undefined reference to `_UPT_create' test-ptrace.c:(.text+0xbf0): undefined reference to `_UPT_destroy' test-ptrace.c:(.text+0xbff): undefined reference to `_Ux86_64_destroy_addr_space' I've replaced `-lunwind-generic` with `-lunwind-x86_64` since I'm on this arch, and I'm still getting the same error message. Any ideas? Thanks! - Hai Huang
