Yes I am intended to use ifort with gcc. <br>
<br>
I changed ifort versions to one that does not include tbb.<br>
<br>
However, PETSc is still includingÂ
-L/usr/lib/gcc/x86_64-redhat-linux/4.1.2 in petscvariables,
attached you will find an updated petscvariables file.<br>
<br>
ifort is not including any gcc, neither there is reference to this
directory in $PATH or $LD_LIBRARY_PATH, why is PETSc still
including it?<br>
<br>
Thanks for your help,<br>
<br>

Its likely the gcc-4.1 stuff is coming from ifort.
Did you intend to use ifort with gcc? [instead of gfortran?]

I am building PETSc from the git repository and it is strange that once PETSc
is installed the petscvariables (PETSC_WITH_EXTERNAL_LIB) file shows a
different gcc library path that the one from the compiler used and the one
defined in LD_LIBRARY_PATH. This is causing me troubles when using PETSc with
other library that requires libstdc++
Here is the command used to build PETSc:
./configure --prefix=$DEV_lib_dir/petsc_git-debug
--PETSC_DIR=/home/hector/dwnld_prog/petsc --PETSC_ARCH=linux-intel-debug
--CC=mpicc --FC=mpifort --CXX=mpicxx --with-openmp=1 --with-valgrind=1
--with-valgri
nd-dir=/home/hector/installed --with-parmetis-dir=$DEV_lib_dir/parmetis/
--with-metis-dir=$DEV_lib_dir/parmetis/ --with-zoltan-dir=$DEV_lib_dir/zoltan/
--with-hypre-dir=$DEV_lib_dir/hypre --download-ptscotch
--with-blas-lapack-lib=\[${MKLR
OOT}/lib/intel64/libmkl_intel_lp64.a,${MKLROOT}/lib/intel64/libmkl_core.a,${MKLROOT}/lib/intel64/libmkl_intel_thread.a\]
--with-scalapack-include=${MKLROOT}/include
--with-scalapack-lib=\[${MKLROOT}/lib/intel64/libmkl_scalapack_lp64.a,${MK
LROOT}/lib/intel64/libmkl_blacs_intelmpi_lp64.a\] --with-shared-libraries=0
--FC_LINKER_FLAGS="-qopenmp -qopenmp-link static" --FFLAGS="-qopenmp
-qopenmp-link static" --LIBS="-Wl,--start-group
${MKLROOT}/lib/intel64/libmkl_intel_lp64.a ${M
KLROOT}/lib/intel64/libmkl_core.a ${MKLROOT}/lib/intel64/libmkl_intel_thread.a
-Wl,--end-group -liomp5 -ldl -lpthread -lm"
Here is LD_LIBRARY_PATH:
echo $LD_LIBRARY_PATH
/home/hector/installed/gcc-6.1/lib64:/home/hector/installed/gcc-5.1/lib64://home/hector/installed/lib:/home/hector/installed/libraries_intel/openmpi/lib:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/compiler/lib/intel64:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/compiler/lib/intel64_lin:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/mpi/intel64/lib:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/mpi/mic/lib:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/ipp/lib/intel64:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/compiler/lib/intel64:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/mkl/lib/intel64:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/tbb/lib/intel64/gcc4.1:/share/apps/intel3/debugger_2016/libipt/intel64/lib:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/daal/lib/intel64_lin:/share/apps/intel3/compilers_and_libraries_2016.2.181/linux/daal/../tbb/li

Attached you will find the resulting petscvariables file. There in the
definition of PETSC_WITH_EXTERNAL_LIB it is not included the gcc-6.1 directory
and instead gcc4.1 directory is included.
What could be the problem? Thank you for your help.
Best regards,
Hector
