Install TAO

Prerequirement:
PETSC must be installed

edit : include/tao_sys.h
search for the line: extern int PetscLogInfo(void *,const char*,...);
change to: extern int PetscLogInfo(void *,const char[],...);
This is because the prototype in tao_sys.h is different from that in
petsclog.h of PETSC

Run the following commands

export TAO_DIR=`pwd`
export BOPT=O_c++
export PETSC_ARCH=cygwin-intel
make all
make tao_testexamples >& examples.log

check for errors in examples.log
