AIX build fails

[Pete]

I am trying to build protocol buffers on several platforms and I'm
having a problem with building on AIX. I run configure with only the
--prefix option, and have defined these variables:
export CFLAGS="-maix64"
export CPPFLAGS="-maix64"
export LDFLAGS="-maix64"
export OBJECT_MODE=64

Configure runs well, but make fails when linking. Here I have all but
the last few lines:

Can anybody help here?

Thanks,

I figured out the issues here:
The build issue was solved by making sure:
-L/opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/4.2.4/ppc64
Came before:
-L/opt/freeware/lib/gcc/powerpc-ibm-aix5.3.0.0/../..

After fixing this, I had an issue while running the protoc binaries
during the test:

This was fixed by making sure the "-Wl,-brtl" option came before "–
lprotobuf" while linking libprotoc.so.

After those changes, make, make install, and make check all pass.
