Using symbols from

Using symbols from

[Venkatesh Srinivas]

Hi,

I'm using gdb to debug a program on a remote target via IP; the symbol
tables I have are not in a gdb-friendly format.

I have the output of the platform specific nm run against the binary;
is there any way I can teach gdb about the data from nm (at least the
entry addresses to my functions, location of some global variables?).

Thanks,

It's not something that I have tried, so take with a grain of salt.
The only way I can think of is to transform the symbol-table data
into another format that GDB understands (for instance, an ELF symbol
table). For instance, if you could do an objcopy from your format to
ELF, then you can load the symbols from that ELF object file using
add-symbol-file.

Alternatively, link a new "dummy" executable with the same symbols
assigned to matching addresses. This (I think) could be done fairly
easily using GNU-ld linker script.
