Hi, I am adding some code of my own **only** under net/bluetooth in some file there.
There is only exactly one module which is changed by my addition, This is net/bluetooth/bluetooth.ko Now, when I run 'make -j2 modules' it takes quite a time, even If I did one change in one line in a file under net/bluetooth. I assume that it has to do with stage 2 of the build, which says something about ... Building modules, stage 2. MODPOST 855 modules ... see below full log. Now my question is this: Is there a way to make things more efficent when building a module, on the assumption that I do not change anything anywhere except /net/bluetooth (in this case)? somehow telling the MODPOST that only one module is changes ? I remember I once saw (not sure) a suggestion to build only a specified moule like: make net/bluetooth But in this case the result is the same. any ideas? rgs Kevin myhost> make modules make[1]: Nothing to be done for `all'. make[1]: Nothing to be done for `relocs'.
