Re: exporting linker script symbols in statically linked binaries

I am not really clear as to why your code cannot know the names of 
symbols at compile time, but the short answer to your question is "no".

There are tricks that you can try.  You could put a magic number into 
the data section (eg 0x12345678) followed by linker directives to store 
the names of the symbols, and then have your code scan through the data 
section looking for this magic number and the names that follow it.

You could get the name of the executable via the argv[0] element and 
scan the file system for the corresponding file and then parse that.

You could do what David has suggested and write a script to parse the 
output of the linker's -Map option and dump the symbol names/addresses 
into a file which is then read by your program.

Cheers
