I figured there could be a few here who are somewhat gcc saavy. Maybe I'd be lucky enough to find someone who could help me learn this... offlist. Never hurts to ask? Anyway - sorry to bother.

[Slightly OT] Need help with GNU ld
Hi all, I'm sort of lost as to where I might even start with this, and since this group is so fluent (I'm guessing) with GCC, I'm hoping someone here can either answer or point me to where I can go look. (I'm looking on the gnu.org's gplusplus list and am not sure if that's a good source since it seems kind of dead) Anyway - here's my problem. I'm working on an embedded app that uses GCC for its compiler. I have 2 pieces of code that share common library functions from libc.a like memcpy and strlen Because the two pieces are a bootloader and the application, I would like the bootloader to be linked with a completely private set of functions which INCLUDEs the library calls they make. This would duplicate those libc.a calls like memcpy() and strlen() inside the bootloader portion. So my question is (and I might be looking in the wrong place to do this, but it seems like 'ld' would take care of it): How do I tell the ld that for bootloader.o, all library references like memcpy() should be inlined/included with that function. I've got all the functions in the bootloader corralled into the memory space I want, but the functions called in libc.a are shared. 'static' only works for the immediate function while any calls to a libc.a function get shared with the main application. I've already tried the forum for the micro-controller I'm using.. but apparently, it's new enough that I'm too far ahead on the curve for anyone else to help me. (even from the company) Thanks in advance and sorry for bugging all of you here.. if I hear crickets, I'll try and keep digging elsewhere. -Ben -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
