Byte InsightInstalling the FAN Library onto Ubuntu (or not as the case may be).
Setting up the FAN Library for Ubuntu takes some work. I started by trying to install the Python Scientific Library but this didn’t seem to give the packages I wanted.
sudo apt-get install pyton-scientific
So I then looked at doing it from source.
1) Get the Source files from UNiDAta
wget ftp://ftp.unidata.ucar.edu/pub/netcdf/contrib/fan.tar.Z
2) Uncompress them from their delivery package and cd into the src folder.
uncompress fan.tar.Z
tar -xvf fan.tar
cd fan-2.0.3/src
3) Now if you take a moment to read the README and INSTAL files you will realise that you need to install the udunits binaries and development libraries.
sudo apt-get install libudunits2-dev
sudo apt-get install udunits-bin
4) As well as install ingthe netcdf binaries and development libraries
sudo apt-get install libnetcdf-bin
sudo apt-get install netcdf-bin
5) Now you can try and configure the FAN package but before you do there will be things that need configuring such as:
CPP_NETCDF Compiler reference for netCDF header-file, e.g. “-I/usr/local/netcdf/include”. Ubuntu10(ish) /usr/include
CPP_UDUNITS Compiler reference for UDUNITS header-file, e.g. “-I/usr/local/udunits/include”. Ubuntu10(ish) /usr/lib
LD_NETCDF Linker reference for netCDF library, e.g. “-L/usr/local/netcdf/lib -lnetcdf”.
LD_UDUNITS Linker reference for UDUNITS library, e.g. “-L/usr/local/udunits/lib -ludunits”.
And then you can try this
./configure
6) Next try building the install packages
make install
Now at this point I started getting some errors so how did I fix/not fix them. The first error was something to do with MAX_NC_OPEN but I was able to follow this link which appeared to fix the issue. Open the nc header file
pico fanlib/nc.h
and then add this code under the #include entry.
#define MAX_NC_OPEN 32
Rather than just use 32 you can use the script providing on the link above to find out what number your machine can cope with. When I compiled the script and ran it.
gcc sysconf_test.c -o sysconf_test
./sysconf_test
the output was:
daviesc@big-blue:~/software/fan-2.0.3/src$ ./sysconf_text
sysconf _SC_OPEN_MAX says you can use the following:
#define MAX_NC_OPEN 1024
which was perfect so I updated nc.h again. The next error I had was
nasParse.y:30:1: error: initializer element is not constant
which I think was related to my haphazard approach to the Configure section so I went back to step 5 to add some more detail.
Hi chris,
I followed your instructions to install the package in my computer. I am running a linux mint maya 13, MATE-64 bits edition. Here is the complete profile of my distribution: Linux version 3.2.0-23-generic (buildd@crested) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu4) ) #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012.
Everything good until the last error message (nasParse.y:30:1: error: initializer element is not constant) after which I have tried everything with no success. Do you have a hint on how to solve the problem? I was also asked for the location of the xdr library during the configuration process. I would be very grateul if you could help me with this. Many thanks in advance.
Best regards,
