Dear netCDf-users,
there was another question concerning netCDF and Linux - and since
I'm using netCDF's on various platforms including Linux I thought
someone might be interested in the following...
First, I had no difficulties at all to compile netCDF 2.4 beta 6
on Linux (Slackware 3.0 with ELF), and the binaries pass all tests
provided with the distribution.
Then, to include Fortran support, it is sufficient to add a symbolic link
linux.m4 -> f2c.m4
in the `src/fortran' subdirectory before starting the compiling. A script
named `f77' should be available that drives f2c (there is one in the
standard Slackware). As far as I remember the `f2c.m4' file was provided
by myself a year ago or so, and it still works without problems. I actually
worked with an older version (2.3.2) for a long time on both Linux and
Solaris (with f2c instead of a real Fortran compiler), and I never
experienced any problems with the fortran interface.
A note concerning g77: Currently, g77 does not support the byte type, so
I have not yet written an m4-file for this compiler; however, since it
uses the same naming conventions as f2c, they probably will not differ
too much. I might look into this as soon as g77 supports byte and
integer*2...
Finally, Linux now uses the ELF library format (which is available with
Slackware 3.0), providing a simple way to build and use shared libraries.
This reduces the disk space needed by binaries; especially large sets of
programs like GMT will benefit from their availability. I therefore build
a set of ELF shared libraries and patched the Makefiles (or better the
`Makefile.in' and `master.mk.in' files in the distribution of netCDF 2.4b6)
in order to build shared and static libraries. I'll append the diffs at the
end of this mail.
To apply these:
- Untar the netCDF 2.4 beta 6 source code tree from the tar-file;
- apply the patches _without_ cd'ing into the netCDF tree with
patch < file_with_diffs ;
- cd to netcdf-2.4-beta6/src/fortran and add the necessary link
for the fortran interface with the command
ln -s f2c.m4 linux.m4 ;
- run `configure' in the netcdf-2.4-beta6/src subdirectory;
- run `make' and `make test' and `make install'.
Some (now really final) remarks:
c++: I don't know too much about c++, so I just can state that all tests
during `make test' are passed succesfully;
IEEE: For some reason, configure does not detect the correct options to
enable IEEE arithmetic under Linux. It can be enabled using the
`-lieee' option at linktime (i.e., by linking with the `libieee.a'
library). This (and the compilation with 486 optimizations) can be
enforced by calling configure with
CCFLAGS='-m486 -lieee' configure
which will, however, give rise to a warning message during the
compilation of each individual source code file (which can be ignored).
For those who do not like to compile their own version I have prepared
a tar file containing the libraries (static and shared), the ncdump and
ncgen progs, include files and documentation (man pages and info files)
which can easily be installed with Slackware's `installpkg'. They have been
build with `-m486', and they support IEEE arithmatic. Currently, they can
be obtained via anonymous ftp from
strat06.met.fu-berlin.de (160.45.75.6)
^
|
a `zero'
in the pub/netcdf directory. Along with the binary distribution you'll
find the appended diffs, a copy of this mail and another package with
a few contributed programs (nccat, gennet, ncrename, and ncks) which are
linked against the shared libraries.
I do not know how much interest there is in Linux binaries, but I could
continue to provide binary versions of the current netCDF release in static
and shared versions. If enough people think this would be useful, I would
be really thankful if someone could provide an anonymous ftp server;
strat06 is just my (slow) working PC at the university, and it is switched
off sometimes...
I would be happy to receive comments and tips for the patches to make them
more stable and useful.
Regards from Berlin,
Chris Marquardt (marq@xxxxxxxxxxxxxxxxxxxxxxxx)
