Building OpenJDK in Ubuntu 8.04

I tried building OpenJDK in Ubuntu 8.04 on x86 machine. I have come across with some issues which have work-around. After installing all the necessary applications for building JDK and setting environment, building failed with the following error.

<error>
/home/rajendra/jdk7/jdk7/hotspot/src/os/linux/vm/jvm_linux.cpp:179: 
          warning: deprecated conversion from string constant to ‘char*’
make[5]: *** [jvm_linux.o] Error 1
make[5]: Leaving directory 
`/home/rajendra/jdk7/jdk7/build/hotspot/outputdir/linux_i486_compiler2/product'
make[4]: *** [the_vm] Error 2
</error>

It seems new compilers enables -Write-strings by default, work-around for this issue is to hack the make file hotspot/build/linux/makefiles/gcc.make and add the flag 'CFLAGS += -Wno-write-strings'. This solves the gcc failure.

After adding the flag build continued for some time and crashed with the following error.

<error>
/home/rajendra/jdk7/jdk7/build
/gensrc/java/nio/charset/CharsetEncoder.java:142: cannot find symbol
symbol  : class $replType$
location: class java.nio.charset.CharsetEncoder
  private $replType$ replacement;
</error>

Alan bateman has given work-around for this issue which worked for me. Alan suggested me to switch to bash or delete the /bin/sh and create a link "ln -s bash sh". I am happy this work-around solved my issue. After few minutes building again failed with the following error.

<error>
/usr/bin/ld: cannot find -lXtst
collect2: ld returned 1 exit status
make[3]: *** [/home/rajendra/jdk7/jdk7/build/lib/i386/xawt/libmawt.so] Error 1
make[3]: Leaving directory `/home/rajendra/jdk7/jdk7/jdk/make/sun/xawt'
make[2]: *** [all] Error
</error>

For which I don't know the solution. If you have work-around or solution for the above issue please let me know.
