Hello CMAS Forum, I was trying to compile WRF-CMAQ (CMAQv5.4 with WRFv4.4) with the script `./bldit_cctm.csh intel |& tee bldit_cctm_twoway.log`. I followed suggestions in the [WRF-CMAQ tutorial](https://github.com/USEPA/CMAQ/blob/main/DOCS/Users_Guide/Tutorials/CMAQ_UG_tutorial_WRF-CMAQ_Benchmark.md) with the intel compiler. The script created bldmake\_intel.exe, tc.exe, ndown.exe, and real.exe. Unfortunately, the script couldn’t create the wrf.exe. The log file shows: > make[1]: [Makefile:17: em\_wrf] Error 1 (ignored) > make[1]: Leaving directory ‘/home/alejandro/CMAQv54\_WRF/CCTM/scripts/BLD\_WRFv4.4\_CCTM\_v54\_intel/main’ Do you have any best suggestions to fix it? After that error, I tested to compile WRFv4.4 inside the BLD\_WRFv4.4\_CCTM\_v54\_intel directory using ./configure, and it worked. However, I don’t know if with this additional step I can use the WRF-CMAQ correctly. I appreciate your help and suggestions, Alejandro D. Peralta aperalta@usp.br ---

Hi Alejandro, Do you have the “bldit\_cctm\_twoway.log” saved during compilation? If so could you please post it here. Looking within that log file will tell you exactly where the model is failing to compile. Thanks! ---

Hi fsidi, I successfully solved that error when I reinstalled the I/O API 3.2 version 20200828. After that, I ran my script available in ([WRFCMAQ/install\_WRFCMAQ.sh at main · adelgadop/WRFCMAQ · GitHub](https://github.com/adelgadop/WRFCMAQ/blob/main/install_WRFCMAQ.sh)) to install WRF-CMAQ. The problem now is when I tried to install again I/O API 3.2 using the script available in my GitHub ([WRFCMAQ/install\_IOAPI\_libs\_WRF\_CMAQ.sh at main · adelgadop/WRFCMAQ · GitHub](https://github.com/adelgadop/WRFCMAQ/blob/main/install_IOAPI_libs_WRF_CMAQ.sh)) for another user. So, we had errors during the m3tools installation (please see make.log.txt attached). It is a headache for me. I don’t know if there is a problem with the netCDF installation. Best regards!

Most of what you’re seeing is warnings which do not affect the functionality. For the undefined-reference errors: this netCDF library was not built according to the recommendations; you will need additional libraries in the link=flags for anything built with it. See [https://www.cmascenter.org/ioapi/documentation/all\_versions/html/AVAIL.html#ncf4](https://www.cmascenter.org/ioapi/documentation/all_versions/html/AVAIL.html#ncf4): > NetCDF Version 4.x have lots of additional build options, that will require a complex set of additional libraries in your Makefiles and all other model-building systems. It is recommended that you disable these options by adding the command-line flags below to your netCDF configure command: > > `--disable-netcdf4 --disable-dap` > or (depending upon netCDF version; don’t you love consistency and compatibility !?? ) > `--disable-netcdf-4 --disable-dap` ---

Thanks so much, Carlie. Yes, It was the netCDF !!! I used another netCDF that I installed with the two flags that you suggested. The version of this netCDF is 4.1.3; with that, the I/O API 3.2 could be installed. After that, I successfully installed the WRF-CMAQ (the last version). Best regards, Alejandro
