i'm trying to build an 'uptodate' UML guest and see exactly this 'undefined reference to indirect_set_thread_area' (reported in November) with 2.6.15 and all the incrementals from the patch tarball for 2006-01-08 on user-mode-linux.sf.net.
the comment related to this patch says CONFIG_MODE_ TT 'off' ... but this email says try it 'on' and that just leads to: CC arch/um/os-Linux/tls.o arch/um/os-Linux/tls.c:48: error: syntax error before "get_thread_area" arch/um/os-Linux/tls.c:48: warning: type defaults to `int' in declaration of `_syscall1' arch/um/os-Linux/tls.c:48: warning: function declaration isn't a prototype arch/um/os-Linux/tls.c:48: warning: data definition has no type or storage class arch/um/os-Linux/tls.c:49: error: syntax error before "set_thread_area" arch/um/os-Linux/tls.c:49: warning: type defaults to `int' in declaration of `_syscall1' arch/um/os-Linux/tls.c:49: warning: function declaration isn't a prototype arch/um/os-Linux/tls.c:49: warning: data definition has no type or storage class arch/um/os-Linux/tls.c:51: warning: "struct user_desc" declared inside parameter list arch/um/os-Linux/tls.c:51: warning: its scope is only this definition or declaration, which is probably not what you want arch/um/os-Linux/tls.c: In function `do_set_thread_area_tt': arch/um/os-Linux/tls.c:55: warning: implicit declaration of function `set_thread_area' arch/um/os-Linux/tls.c: At top level: arch/um/os-Linux/tls.c:62: warning: "struct user_desc" declared inside parameter list arch/um/os-Linux/tls.c: In function `do_get_thread_area_tt': arch/um/os-Linux/tls.c:66: warning: implicit declaration of function `get_thread_area' make[1]: *** [arch/um/os-Linux/tls.o] Error 1 Blaisorblade wrote: > On Friday 18 November 2005 09:59, Rob Landley wrote: > >> On Friday 18 November 2005 01:58, Blaisorblade wrote: >> >>>> arch/um/sys-i386/built-in.o(.text+0x3b60): In function `load_TLS': >>>> : undefined reference to `indirect_set_thread_area' >>>> >>>> collect2: ld returned 1 exit status >>>> KSYM .tmp_kallsyms1.S >>>> nm: '.tmp_vmlinux1': No such file >>>> No valid symbol. >>>> make[2]: *** [.tmp_kallsyms1.S] Error 1 >>>> make[1]: *** [_all] Error 2 >>>> make: *** [all] Error 2 >>>> >>>> This is progress! >>>> >>> Disable TT mode or play with such things IIRC >>> >> Nope, tt mode already is disabled. >> > > Be creative - enable it then... yep, indirect_... is defined only when TT is > active, but is also used otherwise. > > >>> - actually there's a proper >>> fix along lines of "move #ifdef's inside sys-i386/tls.c to properly cater >>> to dependencies" if you want. >>> >>> This comes from the TLS patches btw... >>> > > >> I'll be banging on this more in a bit... >> > > >> Rob >> > >
