Bug 96783 – linux-headers-2.6 causes build failure on ia64 with dosfstools

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Henrik Grubbström 2005-06-22 07:08:09 UTC]

Emerging of sys-fs/dosfstools-2.11 fails with:

>>> Source unpacked.
make -C mkdosfs all
make[1]: Entering directory
`/var/tmp/portage/dosfstools-2.11/work/dosfstools-2.11/mkdosfs'
gcc -O2 -fomit-frame-pointer -D_FILE_OFFSET_BITS=64 -Wall  -c mkdosfs.c -o mkdosfs.o
In file included from /usr/include/signal.h:333,
                 from mkdosfs.c:58:
/usr/include/bits/sigcontext.h:31: error: redefinition of `struct ia64_fpreg'
make[1]: *** [mkdosfs.o] Error 1
make[1]: Leaving directory
`/var/tmp/portage/dosfstools-2.11/work/dosfstools-2.11/mkdosfs'
make: *** [all] Error 2

which most likely is due to struct ia64_fpreg being defined in both <asm/fpu.h>:

struct ia64_fpreg {
        union {
                unsigned long bits[2];
                long double __dummy;    /* force 16-byte alignment */
        } u;
};

and in <bits/sigcontext.h> (included from <signal.h>):

struct ia64_fpreg
  {
    union
      {
        unsigned long bits[2];
      } u;
  } __attribute__ ((aligned (16)));

It looks like <asm/fpu.h> is aware of the definition in <bits/sigcontext.h>, but
not the other way around.

Reproducible: Always
Steps to Reproduce:
1. Attempt to emerge sys/dosfstools-2.11 on an IA64.
2. Watch it fail.

[Comment 1 SpanKY 2005-06-22 18:37:45 UTC]

does upgrading to linux-headers-2.6.11 fix this ?

[Comment 2 Henrik Grubbström 2005-06-23 01:41:22 UTC]

Yes, upgrading to linux-headers-2.6.11 (~ia64) seems to fix the problem.

[Comment 3 Tim Yamin (RETIRED) 2005-06-24 10:56:09 UTC]

2.6.11 stabled on IA64, thanks!
