Dear all,

I got some problems by compiling netCDF 3.6.0-p1 on a SuSE9.3 Linux box
(64 bit)
This is my compiler Version:

Reading specs from /usr/lib64/gcc-lib/x86_64-suse-linux/3.3.5/specs
Configured with: ../configure --enable-threads=posix --prefix=/usr
- --with-local-prefix=/usr/local --infodir=/usr/share/info
- --mandir=/usr/share/man --enable-languages=c,c++,f77,objc,java,ada
- --disable-checking --libdir=/usr/lib64 --enable-libgcj
- --with-slibdir=/lib64 --with-system-zlib --enable-shared
- --enable-__cxa_atexit x86_64-suse-linux
Thread model: posix
gcc version 3.3.5 20050117 (prerelease) (SUSE Linux)


The problem is that's fstat won't he found. This is used in posixio.c.


If I do comment out the call of fstat it seems to work right. That is
not the best solution but probably gives an idea what is wrong.

I was using the CFLAGS=-fPIC to create a shareable module.


 /*
 * What is the preferred I/O block size?
 */
static size_t
blksize(int fd)
{
 #if defined(HAVE_ST_BLKSIZE)
        struct stat sb;
/*
        if (fstat(fd, &sb) > -1)
        {
                if(sb.st_blksize >= 8192)
                        return (size_t) sb.st_blksize;
                return 8192;
        }
        /* else, silent in the face of error */
#endif
        return (size_t) 2 * pagesize();
}


/*
 * Sortof like ftruncate, except won't make the
 * file shorter.
 */
static int
fgrow(const int fd, const off_t len)
{
        struct stat sb;
/*
        if (fstat(fd, &sb) < 0)
                return errno; */



What else could I do?


cheers

Reimar
