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