其中涉及到的错误是在w3fi74.f中的第422行

1.   ICOMP   = ISHFT(ICOMP,3)
   

复制代码

w3fi72.f和putgb.f出错是因为调用w3fi74.f出错了，所以主要原因应该也在w3fi74上吧。


查阅过资料，可能是数组下标的问题，但是这个我还看不出。用gdb调试过，也调试不出来。怀疑有可能是w3lib在编译安装时的问题，给出w3lib的Makefile：

1. # OPTIONS FOR GFORTRAN
   
2. F77     = gfortran
   
3. FFLAGS  = -g -O
   
4. CFLAGS  = -O -DLINUX
   
5. CC      = gcc
   
6. ARFLAGS =

请问你怎么把错误行号跳出来

这个我是自己就跳出来了。你可以在执行命令里加 -g。
