How to get BACKTRACE (function + line number) on Solaris?

Question

I have done some code in C that happily send the full backtrace with function name and line number to a log file.

This was done using a mixture of backtrace, backtrace_symbols and dladdr and ADDR2LINE on LINUX. Also using the "execinfo.h" on Linux....

So essentially the following:

Backtrace: Line Locations:

signalErrorHandler
/home/lynton/Desktop/TestThreadLeak/TestThreadLeak/./main.c:211
??
??:0
*__GI_raise
/build/buildd/eglibc-2.12.1/signal/../nptl/sysdeps/unix/sysv/linux/raise.c:64
*__GI_abort
/build/buildd/eglibc-2.12.1/stdlib/abort.c:94
__libc_message
/build/buildd/eglibc-2.12.1/libio/../sysdeps/unix/sysv/linux/libc_fatal.c:168
malloc_printerr
/build/buildd/eglibc-2.12.1/malloc/malloc.c:6283
*__GI___libc_free
/build/buildd/eglibc-2.12.1/malloc/malloc.c:3739
threadMainLoop
/home/lynton/Desktop/TestThreadLeak/TestThreadLeak/./main.c:260
start_thread
/build/buildd/eglibc-2.12.1/nptl/pthread_create.c:304
??
/build/buildd/eglibc-2.12.1/misc/../sysdeps/unix/sysv/linux/x86_64/clone.S:114

Now that I have taken the code to Solaris I see it is not supported ;-(

I have tried the pstack approach on Solaris and get something like:

15871:  ./exit_test
-----------------  lwp# 1 / thread# 1  --------------------
 ffffffff7efdaf48 lwp_wait (2, ffffffff7ffffb9c)
 ffffffff7efd34ac _thrp_join (2, 0, 0, 1, 0, ffffffff7ffffb9c) + 38

 ffffffff7efbcc08 system (ffffffff7eaf9ff0, 1ad8, 1800, 0, ffffffff7f13c000, ffffffff7eaf8f18) + 394
 0000000100000fec signalErrorHandler (b, 0, ffffffff7eafbba0, 40000000, 0, 0) + 2bc
 ffffffff7efd6fdc __sighndlr (b, 0, ffffffff7eafbba0, 100000d30, 0, 0) + c
 ffffffff7efcab70 call_user_handler (ffffffff7f500a00, ffffffff7f500a00, ffffffff7eafbba0, 12, 0, 0) + 3e0
 ffffffff7efcad7c sigacthandler (0, 0, ffffffff7eafbba0, ffffffff7f500a00, 0, ffffffff7f13c000) + 68
 --- called from signal handler with signal 0 (SIGEXIT) ---
 ffffffff7ee0052c memcpy (ffffffff7ffffd28, 1fc000, 0, 0, 100001040, 0) + 30
 ffffffff7efd6eb0 _lwp_start (0, 0, 0, 0, 0, 0)

How can I use the above somehow to PROGRAMATICALLY get the LINE NUMBERS and function names as well? I have see something about "walkcontext" or "walkstack"....does anyone have any sample code for me to get line numbers etc?

Also, I have used ADDR2LINE on Linux and it works great.....can someone tell me how to use it on Solaris from the DUMP above? I cannot get it to work ;-(

Any advise will be hugely appreciated

Thanks
