Using makefile, LD_PRELOAD to executable file

I have two files, “abc.c” and “run”

and I want to make a executable binary file which perform below two intstructions

gcc -m32 -O2 -Wall -DRUNTIME -shared -fPIC -o a.so abc.c -ldl
LD_PRELOAD="a.so" ./run

I tried to use makefile in linux, but failed.

Can I use makefile to make executable binary file ?

Answer

Ideally, makefile should be used for compilation. For automating the shell commands, you can use a shell script.

Maybe, in your case, you can write a shell script, which will call the make -f <SomeMakeFile> command first to compile and generate the library (.so) and then run the target binary with alogwith the LD_PRELOAD instruction.
