I downloaded gcc-cplusplus-4.0.0-1.aix5.2.ppc.rpm from IBM AIX Toolbox Download Page - Alphabetical Listing
but:
-bash-3.00# rpm -ivh gcc-cplusplus-4.0.0-1.aix5.2.ppc.rpm
error: gcc-cplusplus-4.0.0-1.aix5.2.ppc.rpm cannot be installed
I can't understand wht kind of error is it... Can be a dependency problem?
-bash-3.00# rpm -qa|grep libstdc
libstdc++-4.0.0-1
libstdc++-devel-4.0.0-1
Moreover I have libc.a and libiconv.a in /usr/lib (and /usr/lib is in $PATH).
