Solution to program errors using math library functions compiled with gcc in Linux-Linux general technology-Linux programming and kernel information. For more information, see the following. Symptoms:
When the math library function is used in the c program and compiled into obj, an error similar to the following occurs when the execution file is generated:
/Tmp/ccalvMPY. o: In function 'main ':

, it is very clear to see. Runtime does not have a constructor (stating that the object cannot be created), but there is a non-static method in the method summary, which has a static getruntime () method. This shows that the runtime class is designed using a single-case design pattern.Import Java.io.ioexception;public class Main {public static void main (string[] args) throws IOException, Interruptedexcep tion {Runtime r = runtime.getruntime ();//Return a process//execute: Run xxxx.exe, call a
