Question

用gcc编译c程序出现 fatal error: graphics.h: No such file or directory compilation terminated.

Answer 1

graphics.h is including a c++ header sstream, you can't use it when compiling with a c compiler, switch your code to c++, that can be done by simply changing the file extension to .cpp for example or .cc and gcc will automatically use g++ when compiling the file.
大致的意思是，graphics.h 这个文件属于c++里面的，应该使用g++来编译，或者是gcc-c++来编译，而你现在是c程序，不支持这个头文件。你再检查下？
