I have recently installed AFL and then its qemu mode, for which I required following packages.
'sudo apt-get install libtool automake bison libglib2.0-dev zlib1g-dev'
With these packages installed qemu installation worked fine. But after its installation whenever I tried to run binary with it, it generated AFL FORK SERVER HANDSHAKE FAILED error. I run my binary independently and it generated this error
cannot execute binary file: Exec format error.
I searched and found out this error is because of conflicting architectures which isn't in my case as I have build and run on same machine. Compiling with libtool also hasnot been a success libtool --mode=compile gcc -c one.c -o testlib.o.
I am also unable to execute any binary I create as default permissions are -rw-rw-r--, so I have to change their mods after creating them. This was not happening before above packages and installations. I even un-installed libtool but no success.
Any suggestions?
This has nothing to do with the libtool installation. I was making a silly mistake by using gcc -c test.c -o test.o which was not performing linking, see this. All I did is use command gcc test.c -o test.o and everything worked fine.
