[petsc-users] C++ compilation error

[Balay, Satish]

Do you get this error with any petsc example – say src/ksp/ksp/examples /tutorials/ex2 ?

Also, copy paste the complete output from make – when building example or your Test code.

Thank you for the response Satish, but I am still encountering the same issue.

Following is my makefile:


PETSC_DIR=/usr/local/pacerepov1/petsc/3.8.3/mvapich2-2.1/intel-15.0/opt/lib/petsc/

include ${PETSC_DIR}/conf/variables
include ${PETSC_DIR}/conf/rules
include ${PETSC_DIR}/conf/test

hello: hello.o  chkopts
        -${CLINKER} -o hello hello.o  ${PETSC_LIB}
        ${RM} hello.o

It is in the format of petsc examples. I am not sure why I am still getting the error.

Presumably PETSc is buit with intel compilers - but somehow gcc/g++ is
getting used via your makefile.

Do you get this error when you use PETSc example with a petsc
makefile? Perhaps you need to format your makefile using petsc
makefile format. For ex: check
src/tao/leastsquares/examples/tutorials/makefile
