Subject: [Boost-build] problems with boost on XFS (calls to file stat fail)

I have an rhel7 (release candidate 2) on an intel64 processor and I'm trying to build the boost library, for x86 (32-bit library).  The first step failed ( because jam0's call to stat failed because the filesystem is XFS.

Is this not an expected usage model?  I configured gcc to a compiler which produces 32-bit binaries before I started the bootstrap step.

Using the exact same steps, with the same compiler, but the boost package on an NFS filesystem, succeeds.

I've traced the difference to a call to the stat(2) function. Here's a simple reproducer:

cat test1.c
#include <sys/stat.h>
#include <stdio.h>
void file_query_posix( char * name)
    struct stat statbuf;
    int stat_return;

    stat_return = stat( name, &statbuf );
printf("stat returns %d for %s %s\n", stat_return, name);

int main(void)
-bash-4.2$ ls -ld .
drwxr-xr-x 9 mblower cmplr 4096 May 28 11:07 .
-bash-4.2$ ls -ld constants.c
-rw-r--r-- 1 mblower cmplr 7436 May 20  2013 constants.c
-bash-4.2$ ./a.out
stat returns -1 for .
stat returns -1 for constants.c

I see other definitions of _FILE_OFFSET_BITS elsewhere in the boost sources, but not under boost_1_55_0/tools
gcc -o bootstrap/jam0 command.c compile.c constants.c debug.c execcmd.c frames.c function.c glob.c hash.c hdrmacro.c headers.c jam.c jambase.c jamgram.c lists.c make.c make1.c object.c option.c output.c parse.c pathsys.c regexp.c rules.c scan.c search.c subst.c timestamp.c variable.c modules.c strings.c filesys.c builtins.c class.c cwd.c native.c md5.c w32_getreg.c modules/set.c modules/path.c modules/regex.c modules/property-set.c modules/sequence.c modules/order.c execunix.c fileunix.c pathunix.c

man 2 stat


              path or fd refers to a file whose size, inode number, or  number of  blocks  cannot  be  represented  in, respectively, the types off_t, ino_t, or blkcnt_t.
             This error can occur when, for example,  an  application  compiled  on  a  32-bit  platform without -D_FILE_OFFSET_BITS=64 calls stat() on a file whose size exceeds
              (1<<31)-1 bytes.

I tried rebuilding jam0 with -D_FILE_OFFSET_BITS=64 and then it worked. There doesn't seem to be a way to configure the build to pass the flag to gcc, and also the build igored the CFLAGS environment value

Thanks and regards, Melanie Blower
