How to run run LMbench on mac

Question

I followed these instructions . Download lmbench3.tar.gz from lmbench3 and unzip LMbench to create a tree like this:

lmbench/
    Results/
    doc/
    scripts/
    src/

And go to the directory lmbenchand entermake results see

But the result is incorrect:

 7 warnings generated.

How to solve it?

Answer 1

You can change the statement

return;

at

return 0;

on line 94 lib_sched.c

Then this file should compile without this error.
