I'm having some problems building and running UML using vanilla 2.6.17-rc4 under x86-64 with glibc 2.4. First of all, it won't build because lack of definitions for some constants in arch/um/os-Linux/sys-x86_64/registers.c. After some digging, I found that these were defined in public setjmp headers in previous glibc's, but have been removed in 2.4. So I copied them from sysdeps/x86_64/jmpbuf-offsets.h, and building went on. Probably, the same happens under i386. Then, it built fine, but at the end several errors showed up: -----------------8<-----------------8<-----------------8<----------------- SYSMAP .tmp_System.map LINK linux Building modules, stage 2.
