Installing PAM radius server on AIX

i was trying to install radius server on our test server running AIX7.3 on it. i have perform following things: 1. Extract the tar file to /tmp where i have downloaded pam_radius-1.4.0.tar.gz. 2. Modify the pam_radius-1.4.0/src/pam_radius_auth.h On line 80, add #define __sun, just before #ifndef CONST 3. Configure and compile the changes > #./configure > # make on executing make command it gives me following error # make cc -Wall -fPIC -c src/pam_radius_auth.c -o pam_radius_auth.o cc: not found make: 1254-004 The error code from the last command is 1. on doing #make CC=gcc it gives me following error and i have no idea how to solve it. Better if anybody explain me error and have some latest Docs on installing r4adius on AIX7.3 # make CC=gcc gcc -Wall -fPIC -c src/pam_radius_auth.c -o pam_radius_auth.o src/pam_radius_auth.c: In function 'rad_converse': src/pam_radius_auth.c:1028:40: warning: passing argument 3 of 'pam_get_item' from incompatible pointer type [-Wincompatible-pointer-types] 1028 | retval = pam_get_item(pamh, PAM_CONV, (CONST void **) &conv);
