perf calls execvp to run the command.. make sure
the program is within the PATH variable location
you can where perf searches by:
[jolsa@krava perf]$ strace -fo out ./perf stat krava
Workload failed: No such file or directory
[jolsa@krava perf]$ cat out | grep exec
5308 execve("./perf", ["./perf", "stat", "krava"], [/* 36 vars */]) = 0
5309 execve("/home/jolsa/libexec/perf-core/krava", ["krava"], [/* 37 vars */])
= -1 ENOENT (No such file or directory)
5309 execve("/home/jolsa/kernel.org/linux-perf/tools/perf/./krava", ["krava"],
[/* 37 vars */]) = -1 ENOENT (No such file or directory)
5309 execve("/usr/lib64/qt-3.3/bin/krava", ["krava"], [/* 37 vars */]) = -1
ENOENT (No such file or directory)
5309 execve("/usr/local/bin/krava", ["krava"], [/* 37 vars */]) = -1 ENOENT
(No such file or directory)
5309 execve("/bin/krava", ["krava"], [/* 37 vars */]) = -1 ENOENT (No such
file or directory)
