Hi all,
I tired to remove a local symbol in an .o file by the use of:
arm-elf-objcopy -N <symbol-name> infile.o outfile.o
This works fine as long as the symbol is global (not weak nor local).
Unfortunately objcopy provides just the conversion of symbols into weak or
local, but no option to convert into global.
Has anyone an idea how I can get rid of an unwanted symbol in an object
file, or how I can change it to be global?
Thanks a lot & Grüße
Wolfgang Haidinger

I don't know whether there is a way, but I do know that the place to
ask is not here, but at binutils@sourceware.org; see
