Hi nick, the gold doesn't help too;
after my reading the ld's code and debugging it, I find the reason of the latter problem: maybe it is due to the gcc's bug( about when using "-g3", some asm-inlined function may be placed in section ".debug_macinfo", but the maintainer doesn't think so), and I use another method of inlining asm code to avoid the latter problem; the first problem about ld is the output of error message "memory exhausted", after reviewing of the src code, I think I can resolve it by modification of the code.

(Essentially it would mean rewriting the linker with minimizing memory usage as the main aim). But ... this does suggest an alternative - have you tried using a different linker ? There are two that I know of that might work for you - the "gold" linker which is currently under development in the binutils project and the linker which comes with the elfutils project. (I am not really involved in the elfutils project so I cannot tell you any more about their linker). The gold linker can be built from the current binutils sources by specifying --enable-gold on the configure command line.

I don't think so. The problem is that you are dealing with a very big program and you are attempting to link it on a machine with only a limited amount of memory. Cheers Nick
