Cross-compiling NetCDF - problems with make

[Dmitar Butrovski <butrovski@xxxxxxxxx>]

Hi everyone,
  
  I'm having difficulties compiling NetCDF 3.6.1 for AROS operating  system (http://freshmeat.net/projects/aros/). I'm running the AROS  development platform hosted on Linux Fedora Core 3. The following steps  describe what I have done and how far I managed to get to.
  
  (1) Configuring with the following settings:
  
  [insurgent@localhost src]$ CC='i386-aros-gcc -nix' FC='' F90='' CXX=''  CC_FOR_BUILD=gcc ./configure --target=i386-aros --host=i386-aros  --build=local
  
  (2) Initially, I got this this error message:
  
  checking for working ftruncate()... configure: error: cannot run test program while cross compiling
  
  (3) I figured from previous forum posts that I should perhaps skip this  test since running in cross-compiling environment, so I have inserted  the 'cross_compiling' flags into ./configure as shown in this snippet:
  
      echo "$as_me:$LINENO: checking for working
 ftruncate()" >&5
  echo $ECHO_N "checking for working ftruncate()... $ECHO_C" >&6
  cross_compiling=no
      if test "$cross_compiling" = yes; then
    { { echo "$as_me:$LINENO: error: cannot run test program while cross compiling
  See \`config.log' for more details." >&5
  echo "$as_me: error: cannot run test program while cross compiling
  See \`config.log' for more details." >&2;}
     { (exit 1); exit 1; }; }
  else
  cross_compiling=yes
    cat >conftest.$ac_ext <<_ACEOF
  /* confdefs.h.  */
  
  (4) Configuring again:
  
  [insurgent@localhost src]$ CC='i386-aros-gcc -nix' FC='' F90='' CXX=''  CC_FOR_BUILD=gcc ./configure --target=i386-aros --host=i386-aros  --build=local
  
  Works fine!
  
  (5) Now, trying to run make - it bails out with the following errors:
  
  [insurgent@localhost src]$ make
  make[1]: Entering
 directory `/home/insurgent/netcdf-3.6.1-beta3/src'

  make[1]: *** [subdir_target] Error 1
  make[1]: Leaving directory `/home/insurgent/netcdf-3.6.1-beta3/src'
  make: *** [libsrc/all]
 Error 2
  
  What these errors and warnings mean?
  What should I try next?
  
  Thanks,
