I've been trying to get the compiler installed and functioning, but I keep running into library problems. After installing it and trying to run configure for a product, the configure failed with collect2: library libm not found. With the help of Google, I then installed the bos.adt.libm package from the AIX installation media. This rang a bell in my head from several years ago with older gcc compiler versions needing some libraries or packages installed from the AIX media, but I cannot find a list of the required requisites anywhere. The next time it failed, collect2 reported issues with /lib/syscalls.exp; I resolved this by installing bos.adt.syscalls from the AIX media. Now it fails with undefined symbols, such as crypt_r, getpass_auto, max_pw_passlen, and max_history_size, among others. In this case, Google isn't helping me much and I haven't been able to identify a package that needs to be installed. Does anyone have a list of known AIX packages required to support gcc, gcc+, and the like? Thanks in advance to anyone that can help..
