First clarification, NO issues happened. I am just curious about the duplicated libraries while I compile PFLOTRAN with PETSc. PETSc version: 3. 16. 2 Configure Options: --configModules=PETSc. Configure --optionsModule=config. compilerOptions --with-make-np=4

<br>
You can send configure.log for your build to petsc-maint<br>
<br>
Generally duplicates should not cause grief. [as one needs them to overcome circular dependencies].<br>
<br>
What issues are you seeing? [send relevant logs]<br>
<br>
If the duplicates are coming form "compiler library" detection part of configure - you can skip this part by listing the correct "compiler libraries"<br>
<br>
for ex: with gcc/gfortran:<br>
<br>
LIBS="-lgfortran -lstdc++"<br>
<br>
However -lgfortran could be required for gcc - but a duplicate for gfortran.<br>
