如何安装gfortran编译器
发布时间:-05-29 22:32:04来源:红联作者:kiger
大家好，我是linux的新手，因论文需要编译一些*.f90的源代码，这两天刚把debian linux装好，网上说要装gfortran的编译器才行，于是我用"sudo apt-get install gfortran"安装了gfortran编译器， 路径为"/usr/bin/"，我用gfortran --version检测了一下，信息如下：
GNU Fortran (Debian 4.3.2-1.1) 4.3.2

gfortran似乎是安装好了，随后，我尝试着用它来编译一个名为Pecube.f90的代码，其实是一连串代码，得到以下错误：
caokai@debian:~/Pecube/source$ gfortran Pecube.f90 -o Pecube

不知是何原因，希望高手指点，谢谢！
