# Compile WRF
## module load GCC ==(5%)==
- Check `module list`
- 

## Install HDF5 + NetCDF ==(15%)==
- Check `which ncdump`

- Report (Why use this flag?)
- enable-parallel : to build a parallel hdf5
- enable-share: 啟用共享,方便啟用其他內置庫
- enable-hl : enables high level library support
- prefix : 配置安裝的路徑
-
## Get WRF.exe ==(0%)==
- Check `tail -15 build_wrf.log`
- 
- 我嘗試了一星期修改configure.wrf但還是出現undefined reference, 以下是我改的內容
- 1. 因error ： undifined "ip" 把CFLAGS -ip -> -p
- sed -i '/^CFLAGS_LOCAL/s/.*/CFLAGS_LOCAL = -w -O3 -ip -DRSL0_ONLY/' configure.wrf

- 2. 用which cpp取代/scinet/niagara/software/2019b/core/bin/cpp

- sed -i 's#/lib/cpp#/scinet/niagara/software/2019b/core/bin/cpp#' configure.wrf

但還是卡在build 階段 ：（
