I have new AIX 5.3L system. Since I could not install openssh-4.3p2 without the C compiler, I downloaded this rpm from IBM. However, when I run rpm -ihv of this rpm, system return with error without any other information. Tried other option of rpm, same error. So Can I install this C compiler for AIX5.3. Half year ago, i installed the gcc-3.3.2-5.aix5.3.ppc.rpm and worked.

Unfortunately, after several dozen hours, I too have been unable to install gcc-4.0.0-1.aix5.3.ppc.rpm for successful g++ use.

Over the last month several people have reported problems that prevented them installing gcc-4 on aix-5.3 from the binary above. Some have reported
partial success with compiling and linking c-only programs.

If you find a solution to installing g++-4 on aix-5.3,
please publish it on this forum in the
"g++-4.0.0 for aix5.3L and stdc++"
topic.

So far, I know the following have been unsuccessfully tried.
o installing from gcc-4.0.0-1.aix5.1.ppc.rpm
o using -isystem, -I, -L, CPATH to override search paths
o altering the gcc spec file

The following met with limited success (i.e. some programs functioned intermittently).
o using the gcc-3 spec file as gcc-4 spec file
o building on aix-5.1 and executing on aix-5.3

I haven't had contact with anyone who tried building gcc-4 from source on aix-5.3.
An ambiguous reference at http://www.gnu.org/software/gcc implies that a bug in aix-5.3's libc.a prevents compilation from source.

Regretfully reporting,

I used the gcc-4.0.0.1 for 5.3 pacakge on the DVD of the "AIX toolbox for Linux Applications for Power System" GNU software 07/2006, comes with the system and it compiled. There are gcc-4.0.0.1 for 5.2 and 5.1 on the same DVD. I also compiled the gcc-C++, but it depends on libgcc++, libstdc++-devel and libstdc++. Now I can compile the openssh and rsync.
