jyoti@jyoti-Compaq-Presario-CQ45-NoteBook-PC:~/lapack/lapack-3.4.2$ make
( cd INSTALL; make; ./testlsame; ./testslamch; ./testdlamch; \
./testsecond; ./testdsecnd; ./testieee; ./testversion )
make: /sbin/sh: Command not found
make: *** [lapack_install] Error 127

thank u..

The default way for a lapack install : sudo apt-get install liblapack-dev

A manual build, A.: Please read the file 'README' :
Old method : "Configuration have to be set in the make.inc file."
The proof way : "LAPACK includes also the CMAKE build."

A manual build, B.:
1) Please start from scratch with a new unpacked lapack-3.4.2.tgz
2) sudo apt-get install cmake gfortran
3) cd lapack-3.4.2/
4) mkdir build
5) cd build/
6) cmake ../
7) make
8) sudo make install

Questions ? You will have to specify Ubuntu version, like Ubuntu 12.04-amd64.

Do not expect everything to work from a manual install.
( You can probably delete the manual build with 'sudo make uninstall' ).
This is the proof solution : sudo apt-get install liblapack-dev
