horrible link times with g++ 4.1.1 and -g

[Egon Kocjan]

Hello,

I am trying to build a ~100 KLOC c++ application with g++ 4.1.1 and 
debugging enabled (-g, no -O...). I also link statically some other 
libraries, like libxml, clucene, etc.., mostly c. The link time with -g 
is really horrible - it is in range of several minutes! I used 3.4.5 
previously, and link time was more like 10-20 seconds. Am I missing 
something obvious here?

Regards,
Egon Kocjan

The linker is not part of gcc.  Assuming you're using the GNU linker,
it's part of binutils, which has its own mailing list.

There have been some speedups in the linker code over the last few
years, so the first thing I'd do would be to try the latest version (or
better, CVS HEAD) and see if the problem is still there.  If so, post to
the binutils list with as many details as you can.
