Dear Help, I'm attempting to compile and link my application code using gcc on an AIX platform with the option -bbigtoc, and I get the following response (missing bigtoc-gcc-3.3.2; see below) that I've cut and pasted below. My sysadmin performed the install of gcc for me. Would you please respond with any suggestion you might have so that my sysadmin to locate and install the offending utility. Thanks in advance.
