CDO

A little follow up:

1. I fixed the problem I reported before, by adding:

export CPPFLAGS="-I/usr/include/udunits2"

to my configure script wrapper.

**

2. So, I've got encouraged to build CDI along with CDO,
and to enable ruby and python therein.

Now my configure line is:

../configure \
--prefix=${MYINSTALLDIR} \
--with-hdf5=yes \
--with-udunits2=yes \
--with-netcdf=yes \
--with-jasper=yes \
--with-grib_api=yes \
--with-libxml2=yes \
--enable-cdi-lib=yes \
--enable-python=yes \
--enable-ruby=yes \
2>&1 | tee configure.log

**

3. However, the Python.h include was not found during configure.
Nevertheless, extending the CPPFLAGS to:

export CPPFLAGS="-I/usr/include/udunits2 -I/usr/include/python2.6"

made it pass the configure and make steps.

Maybe there is a better fix for finding these include files using automake?

**

4. Unfortunately I hit an error during "make check",
which I report as asked:

5. Is the error above a bug in the test only, or would it be a bug in the main code?

In any case, I did "make install", trusting it is an error in the test program only.

6. Finally, I tried to install the pdf and info documentation with:

make install-pdf
make install-info

but there was no effect.

unless you really want a separate CDI installation, you you should skip the $--enable-cdi-lib=yes@ option. CDI is build and statically linked to the CDO binary during the build process. Only if you need the CDI library as an addition to be used by other applications, it makes sense to use this options. Do you need this?

ruby/python bindings for CDI are experimental. They just provide a basic read-interface to CDI-compatible file input (ruby example, python example). Both do not provide the full functionality of CDI. I only tested things against python2.7.

btw I prefer giving the directories to look for libraries instead of yes.

I can check this, but it indicates a problem related to the python script - not CDO. If you need the ruby/python bindings to CDO, use pip for python and gem for ruby

test only.

In any case, I did "make install", trusting it is an error in the test program only.

Just check

 cdo -V

6. Finally, I tried to install the pdf and info documentation with:

make install-pdf
make install-info

but there was no effect.

these are not implemented - CDO has no man-page, because:

• documentation is built-in: cdo -h
• the pdf-docu comes with the source code (cdo.pdf)

Thanks for this information! The check for the udunits2 include file will be improved in the next CDO release.
