How to build NCL and NCAR Graphics from source code

先放一下如何优雅的使用conda安装NCL

Installing NCL with “conda”
参考：使用conda安装ncl：

# install
conda create -n ncl_stable -c conda-forge ncl
source activate ncl_stable
# test
ncl -V
ncl $NCARG_ROOT/lib/ncarg/nclex/gsun/gsun02n.ncl
ncl $NCARG_ROOT/lib/ncarg/nclex/nug/NUG_multi_timeseries.ncl

如果是MacOS，可能会遇到X11系列Error。解决方法是下载XQuartz。

如果服务器恰好没有连网：

还没有完全成功，前期的安装package遇到的问题已经解决，没有办法在linux上安装X11，所以不能用example进行验证
因为想要整洁的环境，所以package全部安装在anaconda3目录下面，如果没有anaconda3可以安装在$HOME/local下面
参考：在Linux上手动安装NCL

在$HOME目录下mkdir package_install
将package上传到package_install

non-optional external softwares:

JPEG:

wget http://www.ijg.org/files/jpegsr9b.zip #先在本地用wget，再上传到服务器
tar -xvf jpegsrc.v9a.tar.gz
cd jpeg-9a 
./configure --disable-shared --prefix=$HOME/anaconda3
make all install

zlib必须要使用1.2.11及以后的版本:

wget https://zlib.net/zlib-1.2.11.tar.gz 
tar -xvf zlib-1.2.11.tar.gz
cd zlib-1.2.11
./configure --prefix=$HOME/anaconda3 --static
make all install

cairo:

# PNG
wget http://prdownloads.sourceforge.net/libpng/libpng-1.6.36.tar.gz
tar -xvf libpng-1.6.36.tar.gz 
cd libpng-1.6.36/
./configure --with-pic --disable-shared --prefix=$HOME/anaconda3 --with-zlib-prefix=$HOME/anaconda3 CPPFLAGS=-I$HOME/anaconda3/include #一定要链接到自己安装的路径
make
make check # should be 33/33 pass
make install

#pkg-config
wget http://pkgconfig.freedesktop.org/releases/pkg-config-0.29.tar.gz
tar -xvf pkg-config-0.29.tar.gz 
cd pkg-config-0.29/
./configure --prefix=$HOME/anaconda3

#FreeType
wget https://sourceforge.net/projects/freetype/files/freetype2/2.9.1/freetype-2.9.1.tar.gz
tar -xvf freetype-2.9.1.tar.gz 
cd freetype-2.9.1/
./configure --prefix=$HOME/anaconda3 --disable-shared

#pixman
wget https://www.cairographics.org/releases/LATEST-pixman-0.38.0
tar -xvf pixman-0.38.0.tar.gz
cd pixman-0.38.0/
./configure --prefix=$HOME/anaconda3
make all install

#cairo
wget http://cairographics.org/releases/cairo-1.16.0.tar.xz
tar -xvf cairo-1.16.0.tar.xz
cd cairo-1.16.0/
/configure --prefix=$HOME/anaconda3 --enable-quartz-font=no --enable-quartz=no --enable-shared=no --enable-static=yes --with-zlib-prefix=$HOME/anaconda3 CPPFLAGS=-I$HOME/anaconda3/include
make all install

pixman/cairo的安装会遇到一些Error：

$PATH/anaconda3/lib/libpng16.a(pngrutil.o): In function png_inflate_claim: $PATH/package_install/libpng-1.6.36/pngrutil.c:429: undefined reference to inflateValidate
or something like undefined reference to inflateValidate@ZLIB_1.2.9
解决方法：检查zlib版本是否为1.2.11及以上，不然会出现错误1；在编译png的时候是否加上--with-zlib-prefix=$HOME/anaconda3 CPPFLAGS=-I$HOME/anaconda3/include，否则会和原本安装在系统中的zlib路径混淆，造成版本错误。

NetCDF：

【记录】在Anaconda（linux）中安装netCDF4库
偷懒了，用了以前安装的netCDF4库，安装路径同样也在anaconda3下面，不知道这个会不会有影响。

HDF-4:

wget https://support.hdfgroup.org/ftp/HDF/HDF_Current/src/hdf-4.2.14.tar
gzip -d hdf-4.2.13.tar.gz 
tar -xvzf hdf-4.2.13.tar
cd hdf-4.2.13/
/configure --prefix=$HOME/anaconda3 --with-zlib=$HOME/anaconda3 --with-jpeg=$HOME/anaconda3 --disable-netcdf
make all install

Build NCL with Source Code

这个方法没有成功的build出ncl，所以选择的是先用source code编译一遍，再把bin替换成precompiled的bin

#download ncl_ncarg-6.6.2.tar.gz
tar -zxvf ncl_ncarg-6.6.2.tar.gz
export NCARG=/home/usr_name/package_install/ncl_ncarg-6.6.2
cd $NCARG/config
make -f Makefile.ini
./ymake -config `pwd` #检查ymake里的第一行sch的路径。如果没有sch会报错：bash: ./ymake: /bin/csh: bad interpreter: No such file or directory。

如果更改了ymake中csh的路径，同样要改的还有ldrel, ymkmf, ymake-install, callconv。

 grep SYSTEM_INCLUDE Makefile
 # SYSTEM_INCLUDE          = "LINUX"
 cd $NCARG
 ./Configure  -v
 # Parent installation directory : /usr/local/ncarg
 # Enter Return (default), new directory, or q(quit) > $HOME/package_install/ncl_install
 # Enter local include search path(s) : /usr/X11R6/include
 # Enter Return (default), new directories, or q(quit) > $HOME/package_install/ncl_install $HOME/anaconda3/include/freetype2
 cd $NCARG
 make Everything  >&  make-output  &
 tail  -f  make-output
 export NCARG_ROOT=$安装ncl的时候选择的路径
 export PATH=$NCARG_ROOT/bin:$PATH
 export MANPATH=$NCARG_ROOT/man:$MANPATH
 # check
 ncl -V (目前安装到这一步，6.6.2）

跑example的时候仍然会报错：
这是因为没有X11，选择使用 wks = gsn_open_wks("png","maponly") ; send graphics to PNG file 就不会报错了
