Generate a simple MAKEFILE file (Python implementation)

Write several tests in LinuxProgram, You need to enter the G ++ command in one line for compilation. when the test is often changedCodeIn this case, it is not as easy as making. The advantage of using makefile is unnecessary. Here I wrote a script to automatically search for the. c file under the current directory (excluding subdirectories) to generate the makefile.
The code here has limited functions (applicable when a single file is an independent test code). You can make some modifications to your needs.

The running effect is as follows (example ):

 1 #./Genmakefile. py
2 Cc = gcc
 3 Cflags =-g-O2-wall
 4  
 5 ALL:
 6 Make pfun1
 7 Make pfun2
 8  
 9 Pfun1 : Pfun1 . O
 10 $ (CC)-O pfun1 pfun1.o
 11  
 12 Pfun2 : Pfun2 . O
 13 $ (CC)-O pfun2 pfun2.o
 14  
 15  
 16 Clean:
 17 Rm-F pfun1
 18 Rm-F pfun2
 19 Rm-f *. o
 20  
 21 . C. O:
 22 $ (CC) $ (cflags)-c-o $ *. o $ <

Run the script and run make.

Appendix:

The above script is inconvenient to use, and then the modification code is as follows:

Rename genmakefile. py to genmakefile and copy it to/usr/local/bin. Then, execute the following command in the required directory:

Genmakefile.
