Hello, Anas.

The problem is in tutorial 4 step 2 right?

coreutils-6.11$ mkdir obj-llvm
coreutils-6.11$ cd obj-llvm
obj-llvm$ ../configure --disable-nls CFLAGS="-g"
... verify that configure worked ...
obj-llvm$ make CC=/full/path/to/klee/scripts/klee-gcc
obj-llvm$ make -C src arch hostname CC=/full/path/to/klee/scripts/klee-gcc
... verify that make worked ...



Did configure finished with no error?
Possibly you cannot install obj-llvm, because its configure finished with 
error....
According to error some python2.7 folder does not exists.
Try to install python2.7 then too if configure passed successfully.

Hi Urmas,
Thanks for the reply.
I am actually referring to the 4th tutorial, the core-utils one.
I want to run klee on gzip 1.6. This is an open source soft, and one needs to 
do configure and make to generate the binaries, similar to what is done in 
core-utils tutorial, but the same commands are not working. Maybe you can throw 
some light on that.


Thanks-Anas

Hello, Anas.

The thing is that according to the tutorial you should use llvm-gcc to compile 
KLEE instrumented program.
http://klee.llvm.org/Tutorial-1.html


llvm-gcc --emit-llvm -c -g get_sign.c
  

I had installed llvm-gcc using terminal command line, "apt-get install 
llvm-gcc" and this worked fine for me.

If default version does not compile instrumented code, then you can try to 
download and install previous version, http://llvm.org/releases/download.html .

Hi Everyone,
I am new to this area. I am trying to run KLEE on gzip 1.6, but am unable to 
gerate the llvm bitcode.


 I used the  make CC=/full/path/to/klee/scripts/klee-gcc  command as described 
in the tutorial. But it is giving this error

Any suggestion on how i can generate the bit code
Thanks-Anas
