The solution is to recompile everything but there is a workaround if you can't do that. This problem first cropped up in RedHat9. Apparently there was a change in the libc. Try to find a copy of the libc from a RedHat8 system. On my systems I created a /usr/local/oldlib with a copy of the RedHat8 libc: % ls -la /usr/local/oldlib -rwxr-xr-x 1 root root 1292588 Oct 21 2003 libc-2.3.2.so % sum /usr/local/oldlib/libc-2.3.2.so 14708 1263 You can then do something like this: % gcc -o program program.c -L/usr/local/oldlib -lc-2.3.2 -limslwhatever Other undefined symbols that can possibly be cured with the same technique are _isAlphNum, __ctype_tolower, and __ctype_toupper. Good luck! Mark Hittinger bugs@xxxxxx
