Description Jim Radford 2002-02-07 17:36:16 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.8) Gecko/20020205

Description of problem:
my readline application uses the library symbol completion_matches.  This
function is exported in 4.1 (and all previous versions), but not in 4.2.  In 4.2
it has been renamed to rl_completion_matches.  This breaks binary compatibility.
 Specifically my application, when compiled with 4.2 (redhat 7.2) will run with
4.1 (redhat 7.1) until I try and complete when I get
a relocation error.

I would expect the library version to be increased to reflect this change.

How reproducible:
Always

Steps to Reproduce:
#include <stdio.h>
#include <readline/readline.h>
int main(int c, char **v) {
  completion_matches("test",rl_filename_completion_function);
}
compile this on a 7.2 machine and run it on a 7.1 machine.
gcc -o tmp tmp.c -lreadline -ltermcap


Actual Results:  ./tt: relocation error: ./tt: undefined symbol:
rl_filename_completion_function

That's why we're shipping the readline41 compat package. Use that.
