This error is strange. The issue does not come up in petsc build - but in petsc4py build.
I see the petsc4py build is with: >>>>>> + CFLAGS=' -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic' mpicc -pthread -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -O3 -fPIC -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -DPETSC_DIR=/usr -I/usr/include/openmpi-x86_64 -I/usr/include/openmpi-x86_64/hypre -I/usr/lib64/gfortran/modules/openmpi/petsc -I/usr/include/openmpi-x86_64/petsc -I/usr/include -Isrc/include -I/usr/lib64/python3.6/site-packages/numpy/core/include -I/usr/include/python3.6m -c src/PETSc.c -o build/temp.linux-x86_64-3.6/src/PETSc.o <<< I've attempted a petsc+petsc4py build using both the following on fedora-31 [with petsc-3.12/maint] - and there were no errors >>> CFLAGS=' -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic' CFLAGS='-fexceptions -fPIC -fstack-protector-strong -g -grecord-gcc-switches -m64 -mtune=generic -O2 -O3 --param=ssp-buffer-size=4 -pipe -pthread -Wall -Wp,-D_FORTIFY_SOURCE=2' <<<<< gcc (GCC) 9.2.1 20190827 (Red Hat 9.2.1-1) petscconf.h has: #define PETSC_DEPRECATED_ENUM(why) __attribute((deprecated)) #define PETSC_DEPRECATED_FUNCTION(why) __attribute((deprecated)) #define PETSC_DEPRECATED_MACRO(why) _Pragma(why) #define PETSC_DEPRECATED_TYPEDEF(why) __attribute((deprecated)) Satish On Sun, 22 Dec 2019, Smith, Barry F. wrote: > > Please send configure.log and /usr/include/openmpi-x86_64/petsc/petscconf.h > > In theory our configure checks if deprecated can be used for Enums but > perhaps our test is not complete. > > Barry > > > > On Dec 22, 2019, at 12:01 PM, Antonio Trande <anto.tra...@gmail.com> wrote: > > > > Hi all. > > > > I don't know of these are errors related to petsc4py or to PETSc, i'm > > writing a mail to this mailing list too. > > Issue reported to petsc4py folks: > > https://bitbucket.org/petsc/petsc4py/issues/133/compiling-petsc4py-3110-against-petsc-3113 > > > > > > In file included from /usr/include/openmpi-x86_64/petsc/petscsys.h:14:0, > > from /usr/include/openmpi-x86_64/petsc/petscbag.h:4, > > from /usr/include/openmpi-x86_64/petsc/petsc.h:5, > > from src/petsc4py.PETSc.c:591, > > from src/PETSc.c:4: > > /usr/include/openmpi-x86_64/petsc/petscconf.h:85:36: error: expected ',' > > or '}' before '__attribute' > > #define PETSC_DEPRECATED_ENUM(why) __attribute((deprecated)) > > ^ > > /usr/include/openmpi-x86_64/petsc/petscksp.h:430:76: note: in expansion > > of macro 'PETSC_DEPRECATED_ENUM' > > #define KSP_DIVERGED_PCSETUP_FAILED_DEPRECATED > > KSP_DIVERGED_PCSETUP_FAILED PETSC_DEPRECATED_ENUM("Use > > KSP_DIVERGED_PC_FAILED (since v3.11)") > > > > ^ > > /usr/include/openmpi-x86_64/petsc/petscksp.h:452:15: note: in expansion > > of macro 'KSP_DIVERGED_PCSETUP_FAILED_DEPRECATED' > > KSP_DIVERGED_PCSETUP_FAILED_DEPRECATED = -11, > > ^ > > In file included from src/PETSc.c:4:0: > > src/petsc4py.PETSc.c: In function '__pyx_f_8petsc4py_5PETSc_KSP_Converged': > > src/petsc4py.PETSc.c:35723:22: error: 'KSP_CONVERGED_ITERATING' > > undeclared (first use in this function) > > (__pyx_v_r[0]) = KSP_CONVERGED_ITERATING;
