[luxInteg]

Greetings,

I am attempting to compile openJDK-7  on a computer whth these:-
--cpu amd64 2cores
--OS cblfs 64-bit linux gcc-4.5.2 kernel-2.6.35.7 jdk-6u24, ant-1.8.1, 
make-3.82,unzip-5.55,zip-3.0


here are the environmental  veriables I have set:-
------------------------

export PATH=/usr/bin:/opt/jdk/bin:/opt/ant/bin:${PATH}
export ALT_BOOTDIR=/opt/jdk
#export ALT_CACERTS_FILE
export ALT_DEVTOOLS_PATH=/usr/bin
export BUILD_NUMBER=b29{ or 38}
export ARCH_DATA_MODEL=64
------------------------
#######  the build ends like this

       Apparently, your bootstrap JDK is version

I have tried the following  all with the same results:-
--versions: openjdk-7-ea-src-b138-14_apr_2011  AND  openjdk-7-ea-src-
b129-10_feb_2011
--with the environmental varialbe LC_ALL="C"
--with environmental variables CC, CXX,  CFLAGS,CXXFLAGS,LDFLAGS and CPPFLAGS 
set
--withOUT environmental variables CC, CXX,  CFLAGS,CXXFLAGS,LDFLAGS and 
CPPFLAGS set

advice would be appreciated

yours sincerely
