This can be solved by building a -current config(8) first. This is generally required. With luck config(8) will die before 4.0... However, it still builds on 3.x systems. : - gcc 2.7.2 can't compile a -current kernel. The problem is that : the asm constraints in i386/include/atomic.h aren't compatible : between 2.7.2 and ECGS. Neither Matt Dillon nor Alan Cox (they're : the two people I know have been working on those constraits) have : been able to come up with a solution. The work-arounds I can : think of are either build/install ECGS first, or replace the : -current i386/include/atomic.h with the one from -stable before : compiling the kernel. The latter produces a cleanly linked : kernel. I had some patches that tried to work around this, but there were too many problems with them. Easier to build egcs... : I can't quickly check whether the resultant kernel actually works, : and whether it is compatible enough with a -stable world to enable : you to build and install a -current world. Somewhere I have ifdefs to atomic.h. It basically replaced it with the -stable version if GNU_C_MINOR was 7 or less. I know that it won't work for MP kernel. Alan Cox had some concerns with booting kernels using the old atomic.h, but I don't recall what they were.
