R mixed with AIX-like Iconv CookBook.

1. 32bit Cooking
    gzip -dc libiconv-1.12.tar.gz|tar xf -
    mv libiconv-1.12 libiconv-1.12.32
    unset OBJECT_MODE
    pushd libiconv-1.12.32
    ./configure  CC="gcc-4.2"
    make
    popd

2. 64bit Cooking
    gzip -dc libiconv-1.12.tar.gz|tar xf -
    mv libiconv-1.12 libiconv-1.12.64
    export OBJECT_MODE=64
    pushd libiconv-1.12.64
    ./configure  CC="gcc-4.2 -maix64"
    make
    make install       # make merge iconv of the system in the install task of default
    popd

3. merge 32bit shared file in archive for 64bit 
    ar -X32 r /usr/local/lib/libiconv.a libiconv-1.12.32/lib/.libs/libiconv.so.2

4. marge 32bit system iconv object in archive for 64bit
    mkdir /tmp/iconv.32
    pushd /tmp/iconv.32
    iconv32=`ar -X32 t /usr/lib/libiconv.a`
    ar -X32 x /usr/lib/libiconv.a
    ar -X32 r /usr/local/lib/libiconv.a ${iconv32}
    rm -f ${iconv32}
    popd
    rmdir /tmp/iconv.32

5. check libiconv
    $ ar -X32 t /usr/local/lib/libiconv.a
    libiconv.so.2
    shr4.o
    shr.o
    $ ar -X64 t /usr/local1/lib/libiconv.a
    libiconv.so.2
    shr4_64.o

6. use gnu iconvlib configuration

   ./configure    --prefix=/usr/local/R-2.7.1 \
                  --enable-R-shlib \
		  --enable-BLAS-shlib \
		  --with-tcl-config=/usr/local/lib/tclConfig.sh \
		  --with-tk-config=/usr/local/lib/tkConfig.sh \
		  CC="gcc-4.2 -maix64 -pthread" \
		  F77="gfortran-4.2 -maix64 -pthread" \
		  FC="gfortran-4.2 -maix64 -pthread" \
		  CXX="g++-4.2 -maix64 -pthread" \
		  CFLAGS="-O2 -g -mcpu=power4" \
		  FFLAGS="-O2 -g -mcpu=power4" \
		  FCFLAGS="-O2 -g -mcpu=power4" \
		  CXXFLAGS="-O2 -g -mcpu=power4" \
		  LDFLAGS="-L/usr/local/lib" \
		  CPPFLAGS="-I/usr/local/incluse"

    # You must appoint the search pass of iconv in CPPFLAGS and LDFLAGS by all means.

    Please enjoy chaos of AIX!!

Chaos.1
    openmp of gfortran for AIX is different from the standard in aligning it.

Chaos.2
    tools::checkFF of gcc for R is unstable.

Chaos.3
    To Be Continued.....
