can't build on linux system...

[Ed Hartnett]

Howdy all!

I am trying to build pnetcdf on a very plain linux system, but it is
not working.

I configure like this:

CC=mpicc ./configure --with-mpi=/shecky/local --prefix=/shecky/local_pnetcdf --disable-fortran

But when I build, I get an error:
/shecky/local/bin/mpicc -c -g -O2 -I.    attr.c
In file included from ncx.h:32,
                 from attr.c:14:
nctypes.h:12: error: conflicting types for ‘ptrdiff_t’
/usr/lib/gcc/x86_64-redhat-linux/4.3.0/include/stddef.h:152: error: previous declaration of ‘ptrdiff_t’ was here
make[3]: *** [attr.o] Error 1
make[3]: Leaving directory `/upc/share/ed/downloads/parallel-netcdf-1.0.2/src/lib'
make[2]: *** [all] Error 2
make[2]: Leaving directory `/upc/share/ed/downloads/parallel-netcdf-1.0.2/src'
make[1]: *** [subdir_target] Error 1
make[1]: Leaving directory `/upc/share/ed/downloads/parallel-netcdf-1.0.2'
make: *** [src/lib/all] Error 2

This is on platform: 

bash-3.2$ uname -a
Linux shecky.unidata.ucar.edu 2.6.26.3-29.fc9.x86_64 #1 SMP Wed Sep 3 03:16:37 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux

I note that the configure does not find ptrdiff_t. From the
config.log:

configure:8131: mpicc -c -g -O2  conftest.c >&5
conftest.c: In function 'main':
conftest.c:96: error: 'uchar' undeclared (first use in this function)
conftest.c:96: error: (Each undeclared identifier is reported only once
conftest.c:96: error: for each function it appears in.)
conftest.c:96: error: expected expression before ')' token
configure:8137: $? = 1

The mpicc compiler has this to say for itself:
bash-3.2$ mpicc --version
gcc (GCC) 4.3.0 20080428 (Red Hat 4.3.0-8)

Does any of this seem familiar to anyone? What am I doing wrong here?

Thanks!

Ed
