Error in processing. System NOT successfully generated.

My directory structure is /tools/altera/quartus5 and nios2 is in /tools/altera/kits

Operating system is redhat 7.3

Path variables given in bash_profile are given below

PATH=$PATH:/tools/altera/quartus5/bin

export QUARTUS_ROOTDIR=/tools/altera/quartus5

export SOPC_BUILDER_PATH=/tools/altera/kits/nios2

export niosbin=/tools/altera/kits/nios2/bin

export niosgnu=/tools/altera/kits/nios2/bin/nios-gnupro/bin

Can any one help me to reolve this problem.

Thanking You in advance
