From PETSc 3.5 to 3.6 my Fortran code stopped compiling, even with the
updated FindPETSc.cmake. I figured out it was because the Fortran
headers moved from $PETSC_DIR/include/finclude to
$PETSC_DIR/include/petsc/finclude. Therefore any F90 code with a
statement like

#include <finclude/petscsys.h>

would need to be changed to

#include <petsc/finclude/petscsys.h>

in the source files which is a bit of work (hypothetically more for
people with bigger codes than mine) and breaks the source from working
with PETSc <=3.5. I attached a minimal example of a code that breaks
from the 3.5 to 3.6 PETSc update. Note: I found a work around by
changing the attached CMakeLists.txt by editing the line

include_directories(${PETSC_INCLUDES})

to become

include_directories("${PETSC_INCLUDES}/petsc" "${PETSC_INCLUDES}")

which works for both 3.5 and 3.6 without editing my F90 source files
by simply exhaustively putting all the options of where finclude might
be in the include path. While I am fine with this, I thought I'd post
something to draw attention to the issue if you want to change it. For
example, defining a PETSC_Fortran_INCLUDES variable in FindPETSc.cmake
that automatically points to the fincludes directory regardless of the
PETSc version would avoid the need for the above trick (though it does
work).

Here is the example: main.F90

PROGRAM main
#include <finclude/petscsys.h>
PetscInt :: i
END PROGRAM

and CMakeLists.txt

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "${CMAKE_SOURCE_DIR}/cmake/Modules/") # Where I have my FindPETSc.cmake

cmake_minimum_required` (VERSION 2.8.8)
project (HELLO)
enable_language (Fortran)

find_package(PETSc REQUIRED)
include_directories(${PETSC_INCLUDES})

find_package(MPI REQUIRED)
add_definitions(${MPI_Fortran_COMPILE_FLAGS})
include_directories(${MPI_Fortran_INCLUDE_PATH})
link_directories(${MPI_Fortran_LIBRARIES})

add_executable(main.x main.F90)
target_link_libraries(main.x ${PETSC_LIBRARIES}  ${MPI_Fortran_LIBRARIES})

Pleas let me know if you can offer any advice on resolving the following problem:

I set up a small repository to learn how to use FindNetCDF. The repository has just two Fortran source files, only one of which depends on NetCDF as specified in a single use netcdf statement. An abbreviated transcript of my results using my repository's add-cmake-file branch follows:

$ git clone --recursive https://github.com/sourceryinstitute/learning-cmake-find.git
$ cd learning-cmake-find
$ git checkout add-cmake-file
$ mkdir build
$ cd build 
$ FC=gfortran cmake ..

I'm trying to use the CMake module to find the PETSc installation that I built on Ubuntu 19.04. I am setting both environment and CMake variables for PETSC_DIR and PETSC_ARCH but I still get the following error message:

-- PETSC_DIR: /petsc
-- PETSC_ARCH: mpi-real-double
CMake Error at /usr/share/cmake-3.13/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  PETSc could not be found.  Be sure to set PETSC_DIR and PETSC_ARCH.
  (missing: PETSC_INCLUDES PETSC_LIBRARIES PETSC_EXECUTABLE_RUNS) (found
  version "3.11.1")

Any ideas?

Hello, I have copied the FindPETSc.cmake to /usr/share/cmake-3.7/Modules (where all the other .cmake files are). However, when I run cmake the following message is shown:

" By not providing "FindPETSC.cmake" in CMAKE_MODULE_PATH this project has
asked CMake to find a package configuration file provided by "PETSC", but
CMake did not find one. "

This is how FindPETSc.cmake is called in my top level CMakeLists:
find_package(PETSC)
if(PETSC_FOUND)
include_directories(${PETSC_INCLUDE_DIR})
add_definitions( "-DHAS_PETSC" )
endif()

Could you please provide more information?

Thank you.

I tried to use the installed petsc (3.1) and one I compiled from source (3.6) but I can't get them to work. In both cases I get

-- Recognized PETSc install with single library for all packages
-- Performing Test MULTIPASS_TEST_1_petsc_works_minimal

-- Performing Test MULTIPASS_TEST_4_petsc_works_all
-- Performing Test MULTIPASS_TEST_4_petsc_works_all - Failed
-- PETSc could not be used, maybe the install is broken.

I am able to compile and run the examples in the petsc source.

On a machine like Summit at ORNL, executables built for the compute nodes need to be invoked via jsrun. I can get the tests that ship with PETSc to work by specifying --with-mpiexec=jsrun -a 1 -c 1 -g 1 at configure time. I'm wondering if it might be a good idea to have the tests that are run by the FindPETSc.cmake module use the MPIEXEC that is specified in the PETSc configuration. This should allow the FindPETSc module to work on Summit, instead of having to force PETSC_EXECUTABLE_RUNS to ON.

I haven't written any CMake code in ten years and I don't remember how to do anything, so I don't know how hard it is to get CMake to grab the right things from the PETSc configuration or whether there might be some good reason to not want to do this.

Update: I'm messing with FindPETSc.cmake because a project I'm working on uses that. I now see that @jedbrown's cmake-modules README states that we should probably be using FindPkgConfig instead. I have not used this and don't know if it makes the above issue moot, or if it will run into the same issue. (Does it need to run anything?)

hi -

I am compiling a software (gridpack) which depends on petsc. spack install petsc installs fine, but doesn't seem to have PETSC_ARCH set. The following messages suggests it is expecting another file: "${PETSC_DIR}/${PETSC_ARCH}/conf/PETScConfig.cmake")

that I am not sure of its origin ... is there anything I am missing here?

Thanks

I have a petsc build on OSX with PETSC_ARCH=gcc-9.2.0^openmpi-3.1.1. The '^' character in the folder name seems to cause a call to echo in ${petsc_config_makefile} return bad data. Investigating a little more, it seems the behavior of 'echo' is notoriously non-portable, especially when used with flags and variables that contain dashes.

Problem in FindPETSc.cmake Line 159:
\t-@echo -n ${${VARIABLE}}

Proposed solution:
\t-@printf '%s' ${${VARIABLE}}

The proposed solution solves my build error, I just wasn't sure if it would cause any issues with other build configurations.

Dear,
When using ccmake to install bitpit, I get the following error:

CMake Error at
/usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137

However, I have set all environmental variables (PETSC_DIR, PETSC_ARCH, PETSC_INCLUDES, PETSC_LIBRARIES and PETSC_EXECUTABLE_RUNS). Does anybody know how to solve this?
Note: my os is ubuntu 18.04

FindPETSc does not respect MPI include paths and therefore fails to compile the tests on systems with scoped mpi installs such as OpenMPI on Ubuntu 16.04 (/usr/include/openmpi/mpi.h)

It should include MPI_INCLUDE_DIRS, or similar here.

A possible solution is to adapt FindPETSc to call FindMPI internally.

I use it like

find_package(PETSc 3.6 REQUIRED)
include_directories(${PETSC_INCLUDES})

add_library(mylib ${sourcesAllNoMain})
target_link_libraries(mylib PUBLIC ${PETSC_LIBRARIES})

Is there something I should or can do about that? I compiled petsc from source using the git maint branch.

Best Thanks!

The fix of 2e65c1c to allow an absent PETSC_ARCH does not seem to work. From a bit of debugging it looks like that foreach (arch ${_petsc_arches}) skips over empty strings. Thus it does not try to the empty version of PETSC_ARCH.

As fix I have tried adding

  if (NOT PETSC_ARCH)
    message (STATUS "Trying without PETSC_ARCH")
    find_path (petscconf petscconf.h
      HINTS ${PETSC_DIR}
      PATH_SUFFIXES include bmake
      NO_DEFAULT_PATH)
    if (petscconf)
      message (STATUS "Install without PETSC_ARCH found")
      set (PETSC_ARCH "" CACHE STRING "PETSc build architecture")
      set (PETSC_ARCH "")
    endif (petscconf)
  endif (NOT PETSC_ARCH)
  set (petscconf "NOTFOUND" CACHE INTERNAL "Scratch variable" FORCE)

after the foreach loop that tries to detect the PETSC_ARCH.

This fortunately fixes the problems on my system, though with my minimal knowledge of CMake I am far from sure if this is a/the correct solution to the problem. I have already noticed two things:

• The line set (PETSC_ARCH "") is needed, otherwise PETSC_ARCH will remain at NOT_FOUND
• Every time I run cmake again it will try to rediscover the PETSC_ARCH. I guess this happens due to that the check if discovery is needed (if (PETSC_DIR AND NOT PETSC_ARCH) on line 100) will be always be false on a system where PETSC_ARCH is empty.

P.S.
The system is a standard Arch Linux, where PETSc is installed using the AUR. Thus it is located in /opt/petsc/linux-c-opt/, with PETSC_DIR=/opt/petsc/linux-c-opt/ and no PETSC_ARCH set.

Hello,

I have

find_package(PETSc 3.6 REQUIRED)
add_definitions(-DPETSC_MAJOR=${PETSC_VERSION_MAJOR} -DPETSC_MINOR=${PETSC_VERSION_MINOR})
message("PETSC VERSION: " ${PETSC_VERSION} )
message("PETSC VERSION: " ${PETSC_VERSION_MAJOR} " . " ${PETSC_VERSION_MINOR} )

To use some conditional compiling based on the PETSc version. (if there is a better way, let me know please!)

It works fine when cmake is ran on an empty directory:

The define is also set correctly. But when I run the same command a second time

% cmake ../..
-- Build configuration: Debug

PETSC VERSION:
PETSC VERSION:  .

The values are empty. Also the defines for the following make are set to empty values.

Not really sure, if that is a problem of my config, or cmake or the module...

Thanks!

I included your FindPETSc.cmake and dependencies and made it work.

However, when specifiying a required version, the module does not fail when the version requirement is not met. I use the git maint branch, i.e. my version is 3.8.1. according to petscversion.h.

find_package (PETSc 3.20 REQUIRED) gives output:

The FindBoost.cmake, that is shipped with CMake, fails if the required version is not met. I think this package should do so, too.

Having
project(preCICE LANGUAGES CXX C) at the top of my CMakeLists.txt, find_package(PETSc 3.6 REQUIRED) works fine.

However, when I omit the C language, it fails. I am not entirely sure, if this is a bug, but since PETSc is used without problems inside this C++ only project, imho it should not need the C language flag.

Thanks!

Hello,
FindPETSc.cmake does not work on Ubuntu 16.04.
This is because the directory structure of /usr/lib/petscdir/3.6.2 does not correspond to a usual one (e.g. as on Ubuntu 14.04). The directory /usr/lib/petscdir/3.6.2 only contains a single directory, with the architecture as its name (e.g. linux-gnu-c-opt). It does not contain bin, conf, include, lib.

Sorry, my mistake

From precice/precice#878

Hello,

I am not sure if the environment is misconfigured or rather an edge case that should be fixed in FindPETSC.

Thanks!

Hi, I am trying to use cmake to compile our fortran project (don't ask why, I was to told to...), I am new to
cmake and I struggled days just to make mpi work..., now and I got the error as

" CMake Error at cmake-modules/FindPETSC.cmake:171 (resolve_includes):
Unknown CMake command "resolve_includes".
Call Stack (most recent call first):
CMakeLists.txt:117 (find_package)"

I add a directory cmake-modules to put the files CorrectWindowsPaths.cmake, FindPETSc.cmake, FindPackageMultipass.cmake and ResolveCompilerPaths.cmake which I have gotten from you.
and the following is my CMakeLists.txt on top level:

cmake_minimum_required (VERSION 2.6)
project (XXXX)
enable_language (Fortran CXX C)
find_package(MPI)
set(CMAKE_Fortran_COMPILE_FLAGS "${CMAKE_Fortran_COMPILE_FLAGS} ${MPI_Fortran_COMPILE_FLAGS}")
set(CMAKE_Fortran_LINK_FLAGS "${CMAKE_Fortran_LINK_FLAGS} ${MPI_Fortran_LINK_FLAGS}")
include_directories(SYSTEM ${MPI_Fortran_INCLUDE_PATH})
list (APPEND CMAKE_MODULE_PATH "./cmake-modules")
set (PETSC_DIR "/home/tjz/work/petsc-intel")
set (PETSC_ARCH "linux-gnu-gcc")
find_package(PETSC REQUIRED)
if(PETSC_FOUND)
message(STATUS "Found Petsc: ${PETSC_FOUND}" )
endif(PETSC_FOUND)

Could you please give me some help on solving this error, thank you very much!
