求助：WRF安装前Test #4: 和 NetCDF出现错误

laiber

华为云服务器  CentOS 7.6 64bit with ARM
按照官网教程来的，到System Environment Tests 的Test #4出现问题，网上找了很久没查到解决方法

[root@ecs-kc1-large-2-linux-20200408152217 TESTS]# gcc -c -m64 TEST_4_fortran+c_c.c
gcc: error: unrecognized command line option ‘-m64’
[root@ecs-kc1-large-2-linux-20200408152217 TESTS]# gfortran -m64 TEST_4_fortran+c_f.o TEST_4_fortran+c_c.o
gfortran: error: TEST_4_fortran+c_f.o: No such file or directory
gfortran: error: TEST_4_fortran+c_c.o: No such file or directory
gfortran: error: unrecognized command line option ‘-m64’


然后没有解决之后准备直接安装NetCDF，到./configure这一步出现如下问题
[root@ecs-kc1-large-2-linux-20200408152217 netcdf-4.1.3]# ./configure --prefix=$DIR/netcdf --disable-dap \--disable-netcdf-4 --disable-shared
configure: netCDF 4.1.3

跪求指教^_^

-m64 是Linux系统的命令吧。你用的教程是 针对CentOS系统的吗

ARM的锅居多，因为不同平台编译器的使用存在区别的，X86-64的命令直接搬到ARM平台翻车很正常的
编译器说明如下
These `-m’ switches are supported in addition to the above on AMD x86-64 processors in 64-bit environments.
-m32
-m64
-mx32
Generate code for a 32-bit or 64-bit environment.

The -m32 option sets int, long and pointer to 32 bits and generates code that runs on any i386 system.
The -m64 option sets int to 32bits and long and pointer to 64 bits and generates code for AMD’s x86-64 architecture.
The -mx32 option sets int, long and pointer to 32 bits and generates code for AMD’s x86-64 architecture.
For darwin only the -m64 option turns off the -fno-pic and -mdynamic-no-pic options.
TESTS的内容去掉-m64就能过，但是configure肯定翻车，因为脚本本身就不支持你的系统LINUX-ARM，所以看看新的脚本有没有支持，要么换成X86-64的云机器再试，其他的就不要想了

谢谢，用X86-64机器已解决
