Compile / link it:

$ gcc -fPIC -O2 -c k.c
$ ld -G k.o -o k.so


Works for me , I am in factory though.


# gcc -shared -rdynamic -march=native -Wall -fPIC $(rpm --eval
%optflags) k.c -o k.so

LD_PRELOAD="./k.so" ls --color=always -l .

cat x --> 74

Hmm, you compiled+linked in one step.
This works here, too:

gcc -shared -fPIC -O2 k.c -o k.so

Can you confirm the failure when compiling + linking
is done in 2 separate steps?

Thank you & have a nice day,
Berny
