Package: dietlibc Version: 0.31-1.2 Severity: normal Tags: patch Hello,
this is a forward of the Ubuntu bug https://bugs.launchpad.net/ubuntu/+source/dietlibc/+bug/381215 While trying to build mksh in Ubuntu karmic (with gcc 4.4) it failed at the linking stage with "undefined reference to `__builtin_stdarg_start'". Here is a test-case (copied from the bug): tgl...@tglase:~$ gcc test.c tgl...@tglase:~$ ./a.out './a.out' called with 1 args tgl...@tglase:~$ rm a.out tgl...@tglase:~$ diet gcc test.c /usr/lib/diet/lib-i386/libc.a(vprintf.o): In function `vprintf': vprintf.c:(.text+0x20): warning: warning: the printf functions add several kilobytes of bloat. /tmp/cccpAo38.o: In function `printfoo': test.c:(.text+0x14): undefined reference to `__builtin_stdarg_start' collect2: ld returned 1 exit status tgl...@tglase:~$ cat test.c #include <stdarg.h> #include <stdio.h> #include <stdlib.h> void printfoo(const char *, ...); void printfoo(const char *fmt, ...) { va_list va; va_start(va, fmt); if (vprintf(fmt, va) < 0) abort(); va_end(va); } int main(int argc, char *argv[]) { printfoo("'%s' called with %d args\n", argv[0], argc); } And here the proposed patch for it: --- dietlibc-0.31.orig/debian/diff/0901-fix-stdarg-gcc44.diff +++ dietlibc-0.31/debian/diff/0901-fix-stdarg-gcc44.diff @@ -0,0 +1,15 @@ +diff -pruN dietlibc-0.31.orig/include/stdarg.h dietlibc-0.31/include/stdarg.h +--- dietlibc-0.31.orig/include/stdarg.h 2009-05-28 10:53:06.000000000 +0200 ++++ dietlibc-0.31/include/stdarg.h 2009-05-28 10:55:12.000000000 +0200 +@@ -9,7 +9,11 @@ __BEGIN_DECLS + #if (__GNUC__ > 2) || ((__GNUC__ == 2) && (__GNUC_MINOR__ >= 96)) + + typedef __builtin_va_list va_list; ++#if (__GNUC__ > 4) || ((__GNUC__ == 4) && (__GNUC_MINOR__ >= 4)) ++#define va_start(v,l) __builtin_va_start((v),l) ++#else + #define va_start(v,l) __builtin_stdarg_start((v),l) ++#endif + #define va_end __builtin_va_end + #define va_arg __builtin_va_arg + #define __va_copy(d,s) __builtin_va_copy((d),(s)) (skipped the changelog entry from http://launchpadlibrarian.net/27233139/dietlibc_0.31-1.2ubuntu2.debdiff) After applying this patch to dietlibc mksh built fine in my Ubuntu karmic pbuilder.
