Unless I'm missing something, I'm surprised nobody has mentioned one |
29 |
potential problem. Unless you are careful, code you compile for an AMD |
30 |
may not run on an Intel. If you are just going to compile binary |
31 |
packages to move and install, this might be OK (assuming you don't trip |
32 |
over trying to run test during a build.) You should be able to come up |
33 |
with settings so compiled code will run on either architecture, but I |
34 |
have no idea what the side effects might be, such as larger and/or less |
35 |
efficient code. I almost wonder if this doesn't count as |
36 |
cross-compiling, even though it is not a totally incompatible |
37 |
architecture. Hopefully someone can either expand on this, or tell me |
38 |
why I'm barking up the wrong tree. |
