1. 下载gfortran (Download the GFortran binary)

gcc-4.3.tar.xz

2. 解压缩到 /(Go into directory under which you want to put GFortran)

#/opt/gcc-4.3
# xz -d gcc-4.3.tar.xz
# tar xvf gcc-4.3.tar

(Unpack the package using tar xvfz gcc-trunk-x86_64.tar.gz, which unpacks it into the directory gcc-trunk. )

3. 设置环境变量

# vim .profile
（在文件的最后添加两行！）
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/gcc-4.3/lib64
export PATH=$PATH:/opt/gcc-4.3/bin

# source .profile

* fortran 编译器位于 /opt/gcc-4.3/bin/gfortran
执行过程需要的库文件位于 /opt/gcc-4.3/lib64

4. 检验
# vim exma.f90

program ABC
A=9.0
B=45
write(*,*) A*B
stop
end

# gfortran exma.f90 -o l123
# ./l123
