[petsc-dev] Build Fails And Warnings In KSP

[Jacob Faibussowitsch]

Hello All,

Seems a recent change introduced the following errors (I have tried make clean, make allfortranstubs, and then rebuild):


     CLINKER master-arch-darwin-c-debug/lib/libpetsc.3.014.2.dylib
duplicate symbol '_kspconvergedrateview_' in:
    master-arch-darwin-c-debug/obj/ksp/ksp/interface/ftn-auto/itfuncf.o
    master-arch-darwin-c-debug/obj/ksp/ksp/interface/ftn-custom/zitfuncf.o
ld: 1 duplicate symbol for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

**************************ERROR*************************************

********************************************************************
gmake[1]: *** [makefile:40: all] Error 1
gmake: *** [GNUmakefile:9: all] Error 2


And warnings (although they appear harmless):


src/ksp/ksp/interface/itfunc.c:2283:39: warning: passing 'PetscReal **' (aka 'double **') to parameter of type 'const PetscReal **' (aka 'const double **') discards qualifiers in nested pointer types [-Wincompatible-pointer-types-discards-qualifiers]
    ierr = KSPGetResidualHistory(ksp, &hist, &n);CHKERRQ(ierr);
