/usr/bin/ld: cannot find /usr/lib64/libasan.so.0.0.0 on redhat

Question

I am normally using valgrind for my c/c++ programs but people have been recommending address sanitizer, so I wanted to test it out, but im having problems linking against it on a redhat system.

I got the following code:

$ cat heap-use-after-free.cpp

int main(int argc, char **argv) {
  int *array = new int[100];
  delete [] array;
  return array[argc];  // BOOM
}

compiling like:

$ g++ -O -g -fsanitize=address heap-use-after-free.cpp

/usr/bin/ld: cannot find /usr/lib64/libasan.so.0.0.0
collect2: error: ld returned 1 exit status

On a redhat where I have installed libasan

sudo yum install libasan

/usr/lib64/libasan.so.1.0.0

Can someone point me in the right direction.

Thanks

It looks like it's looking for an earlier version of the library than you have. Try doing this and see what it says:

sudo yum install /usr/lib64/libasan.so.0.0.0

Also, are you sure that your version of the gcc-c++ package is up-to-date?

The version of the libasan package I have in a CentOS 7 container that works is this: libasan-4.8.5-36.el7_6.2.x86_64.
