Over time and because of different user requirements, I have ended up with 3 versions of gcc installed and, apparently, I use each with a specific version of binutils. Memories are vague, I either found a table indicating which version of binutils is needed by a given version of gcc or I found out the hard way while attempting to use gcc. Presently, I use binutils 2.24 with gcc 4.9.2 binutils 2.25 with gcc 5.3.0 binutils 2.26 with gcc 6.3.0 I am about to install gcc 10.3.0 *Question: which version of binutils should I use?* I can't seem to find a hint about that, anywhere. Thanks, Germán
