This Buildroot .config uses Linux 3.10.7 for the headers. Support for a.out on ARM has been removed in acfdd4b, but this is scheduled for 3.11. 3.10 still had support for a.out. Currently the only archs that still have support for a.out in Linux are: um, m68k, x86 and alpha. Of those, only x86 is meaningfull to Buildroot. So, I think I won't even try to fix this, and simply depend on i386 || x86_64. As far as I am concerned, I use it in my qemu-on-target patchset, and I only expect to run this on x86_64 anyway. We could patch-away the single user of a.out: src/nlist.c . It seems it would be relatively easy to remove a.out support from nlist.c, since there is conditional code guarded by: #ifdef _NLIST_DO_AOUT blabla #endif which is defined by: #if !defined(__NO_A_OUT_SUPPORT) #define _NLIST_DO_AOUT #endif But nothing sets __NO_A_OUT_SUPPORT. The only thing that is properly guarded by _NLIST_DO_AOUT is the inclusion of a.out.h, but is easy to do. So, maybe we should pass __NO_A_OUT_SUPPORT in CPPFLAGS to ./configure Is it really important that this be buildable on !x86 at all? Regards, Yann E.
