This is a resubmission of an entry I made in January but had no replies so I am trying again...
I am debugging some C code under Interix using gdb and need to step into some source that is part of a shared object (.so) file. However, I cannot get to see the code as I get the following message:
(gdb) list my_test_func
7 /tmp/cczLMK6t.s: No such file or directory.
in /tmp/cczLMK6t.s
Rather than taking me to the .c file (which I have forced to be in my gdb source-file-search-path) it looks for some temporary assember file. I have had this problem for some time but have now got to the point where I would really like to get it sorted out. I can work around this by rebuilding the .so as an archive (.a) and rebuilding the application but this is not ideal.
Also <Ctrl>C does not seem to work in gdb when running from an xterm which is a bit of a nuisance.
Does anyone have any suggestions
Thanks

Just so you know, I'm not ignoring the posting.
I haven't heard of being able to step into a shared object with gdb on Interix.
The only workaround is as you noted.

Well, I have now found that this is certainly possible. All this time I have been running gdb as /opt/gcc.3.3/bin/gdb - I was too lazy to edit my login to set it in my search path....until now.
I thought that perhaps I should just try setting my path to include /opt/gcc.3.3/bin and hey-presto! I can now debug my shared object code. And Ctrl-C works when I invoke gcc from xterm too - another bug-bear.
So I am very happy that now I can debug away into all my 60 shared libs!
