[llvm-dev] LLVMSymbolizer: error reading file: No such file or directory

[Alberto Barbaro via llvm-dev]

Hi all,
I'm trying to use klee-uclibc and lli ( I want to use --force-interpreter )
together but I have a small problem. In the present case I'm trying to
execute the following program:

#include<stdio.h>
#include<stdlib.h>

int main () {
   FILE *fp;
   char buffer[1];

   fp = fopen("/bin/ls", "rb");

   fread(buffer, 1, 1, fp);
   fclose(fp);

   printf("Read %d\n", buffer[0]);

   return(0);
}
I compile it using the following bash script:

#!/bin/bash

clang -emit-llvm -c fread.c
llvm-link fread.bc ../lib/fread.os ../lib/fread_unlocked.os
../lib/_stdio.os ../lib/errno.os -o fread-new.bc

Of course the os files were generated compiling klee-uclibc as described on
their web page.

Unfrotunately the output is the following:

✗ lli --force-interpreter examples/fread-new.bc
Unknown constant pointer type!

Any idea on how to fix it please?
