Hi,

I've tried to compile the netCDF3 distribution on a linux system:

I did the following steps:

- unpacking the archive
- configure 
- make
- make test

make test in directory nc_test occured an error:

Making `test' in directory /root/tmp/netcdf-3.1a/src/nc_test
make[2]: Entering directory `/root/tmp/netcdf-3.1a/src/nc_test'
cc -c  -I../libsrc   nc_test.c

    ../libsrc/libnetcdf.a -lm
/nc_test -c
make[2]: *** [test.nc] Floating point exception
make[2]: *** Deleting file `test.nc'

make[1]: *** [subdir_target] Error 1
make[1]: Leaving directory `/root/tmp/netcdf-3.1a/src'
make: *** [nc_test/test] Error 2


I tried to find out what the problem is. So I called make clean in the
nc_test directory and modified the Makefile adding the lines:
CC=gcc
CFLAGS= -g -Wall

result of make:
gcc -c -g -Wall -I../libsrc   nc_test.c
nc_test.c: In function `main':
nc_test.c:102: warning: implicit declaration of function `getopt'
nc_test.c:92: warning: unused variable `optopt'

gcc -o nc_test -g -Wall -I../libsrc    nc_test.o error.o test_get.o test_put.o 
test_read.o test_write.o util.o \
    ../libsrc/libnetcdf.a -lm
ld: Output file requires shared library `libc.so.4'
gcc: Internal compiler error: program ld got fatal signal 6
make: *** [nc_test] Error 1


Strange, I've got the libc.so.4 library. So I made another try. Again I modified
the Makefile: LIBS= -lm -lc
Now everything was compiled correctly (except of the warnings which can
be cleared by adding #include <unistd.h> in tests.h).

But calling nc_test -c results to an 'Floating Exception'.
With the gdb I could figure out the source code line which occurs the error:
In util.c, line 563:
563                     err = nc_put_att_double(ncid, i, ATT_NAME(i,j),
2: j = 3
1: i = -1
(gdb) n
Program received signal SIGFPE, Arithmetic exception.
0x9391a in ncx_put_int_double ()
(gdb) 



Okay. Can somebody help me? Is the problem on my side or is there an error
in the netCDF3 distribution?

Thanks for any hints.

   Tim
