You'll need the PETSC_EXTERN in include/petsc/private/dmpleximpl.h and remove the duplicate prototype listing from src/ts/utils/dmplexts.c

Thanks, the first error that I got was undefined again: arch-ci-linux-cuda-single-cxx/obj/ts/utils/dmplexts.o: In function `DMPlexLandIFunction': 2264 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2264>/home/petsc/builds/KFnbdjNX/0/petsc/petsc/src/ts/utils/dmplexts.c:266: undefined reference to `DMPlexLandFormLandau_Internal' 2265 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2265>arch-ci-linux-cuda-single-cxx/obj/ts/utils/dmplexts.o: In function `DMPlexLandIJacobian': 2266 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2266>/home/petsc/builds/KFnbdjNX/0/petsc/petsc/src/ts/utils/dmplexts.c:305: undefined reference to `DMPlexLandFormLandau_Internal' 2267 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2267>/usr/bin/ld: arch-ci-linux-cuda-single-cxx/lib/libpetscts.so.3.013.3: hidden symbol `DMPlexLandFormLandau_Internal' isn't defined 2268 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2268>/usr/bin/ld: final link failed: Bad value 2269 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2269>collect2: error: ld returned 1 exit status 2270 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2270>gmakefile:149: recipe for target 'arch-ci-linux-cuda-single-cxx/lib/libpetscts.so.3.013.3' failed 2271 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2271>make[3]: *** [arch-ci-linux-cuda-single-cxx/lib/libpetscts.so.3.013.3] Error 1 2272 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2272>make[3]: *** Waiting for unfinished jobs.... 2273 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2273> FC arch-ci-linux-cuda-single-cxx/obj/tao/f90-mod/petsctaomod.o 2274 <https://gitlab.com/petsc/petsc/-/jobs/636864970#L2274>/home/petsc/builds/KFnbdjNX/0/petsc/petsc/lib/petsc/conf/rules:49: recipe for target 'libs' failed https://gitlab.com/petsc/petsc/-/jobs/636864970 I'll try extern

I tried to add code to DMPlexts.c and am getting this error:

https://gitlab.com/petsc/petsc/-/jobs/636828148

dmplexts.c:(.text+0x1a0f): undefined reference to `DMPlexLandFormLandau_Internal' 1648 <https://gitlab.com/petsc/petsc/-/jobs/636828148#L1648>

with this code:

PETSC_INTERN PetscErrorCode DMPlexLandFormLandau_Internal(Vec a_X, Mat JacP, const PetscInt dim, void *a_ctx); /*@ DMPlexLandIFunction @*/ PetscErrorCode DMPlexLandIFunction(TS ts,PetscReal time_dummy,Vec X,Vec X_t,Vec F,void *actx) { ..... ierr = DMPlexLandFormLandau_Internal(X,ctx->J,dim,(void*)ctx);CHKERRQ(ierr);

I tried with EXTERN also. Any ideas? Thanks, Mark
