Hi<br><br>In my case one of the problems was with the linking of libwrfvar.a with libwrfio_nf.a. Therefore, I added "-L$(WRF_SRC_DIRECTORY)/external/io_netcdf -lwrfio_nf \" inbetween the links that are provided under "LIB_BUNDLED" in configure.wrf to overcome the "undefined reference due to ext_ncd_........." type of errors. I was successful in overcoming the error due to this as I realized there is no problem in the installation of my netcdf library. However, I am still facing a problem as follows:<br>

<br>By using this idea I could compile WRF-Var 3.0 without CRTM or RTTOV (used for radiance data assimilation). Since, I am intending to assimlate satellite radiance, therefore I am trying to overcome the above problem for compiling WRF-Var 3.1.1 with CRTM or RTTOV. However, if the problem of yours is same as mine (i.e. undefined reference due to ext_ncd_.........) and you are not intending to use CRTM/ RTTOV then you should be able to compile using this idea as I used. I would be happy to get any suggestions from any users or from wrfhelp.<br>

<b><span style="font-weight: bold;">Objet :</span></b> [Wrf-users] bufr library required for WRF-Var V3.0 or not?<br></font><br><div>Hi</div>
<div> </div>
<div>I am trying to install WRF-Var 3.0 using PGI+gcc compilers in a single processor linux server. I am not able to do it completely. The da_wrfvar.exe is not forming even though other utilities are forming! I discovered the bufr library is linked when the da_wrfvar.f is being compiled to form da_wrfvar.exe! Since other utilities use blas as well as lapack and they are forming it seems the bufr is the culprit! I am thinking I may try to compile without bufr. Is it fine to compile it without bufr library?</div>
<div> </div>
<div>or please let me know how I should compile bufr library so that "undefined reference....." kind of errors would not come.</div>
<div> </div>
<div>Earlier I used to think netcdf is the culprit! However with the netcdf I have compiled and installed WRF modeling system V3.0! So, I feel it is not the culprit. Therefore, my thinking goes to bufr library. It is my humble request to the users to help me in overcoming this problem as I am new to the WRF-Var part!</div>
