我有 Ubuntu 10.04 和 gcc 版本 4.4.3
我一直在尝试安装这个名为 SUPER_LU 的库，其中有一些代码是用 Fortran 编写的。在顶级目录中键入“make”会给我以下错误
gaurish108@gaurish108-laptop:~/Desktop/Research Meetings/PETSC and SUper LU/SuperLU_4.0$ make
( cd INSTALL; make )
make[1]: Entering directory `/home/gaurish108/Desktop/Research Meetings/PETSC and SUper LU/SuperLU_4.0/INSTALL'
g77 -o testdlamch dlamch.o lsame.o dlamchtst.o
***make[1]: g77: Command not found***
make[1]: *** [testdlamch] Error 127
make[1]: Leaving directory `/home/gaurish108/Desktop/Research Meetings/PETSC and SUper LU/SuperLU_4.0/INSTALL'
make: *** [install] Error 2
过去我尝试下载一些数学库时也发生过这种情况？一直认为 g77 cam 与 gcc 捆绑在一起。当我尝试单独安装 g77 时sudo apt-get install g77，这就是我得到的
gaurish108@gaurish108-laptop:~/Desktop/Research Meetings/PETSC and SUper LU/SuperLU_4.0$ sudo apt-get install g77[sudo] password for gaurish108:

我应该怎么办？
