Re: [petsc-users] CMake error in PETSc

2019-12-09 Thread Yingjie Wu

Thank you for your response, Barry
It works for me! I made some minor changes.

I found that there was no petsc.pc in my pkgconfig folder, but PETSc.pc.

So I rewrote it to:

execute_process ( COMMAND pkg-config PETSc .

And the program can run and will not report an DSO error.


Thanks again for your help.

Re: [petsc-users] CMake error in PETSc

2019-12-09 Thread Smith, Barry F.


   The problem is that your Cmake file knows nothing about the MPI compilers 
that are required and hence just selects some random compilers it found in the 
path which do not support MPI.

   I have attached a new CMakeList.txt for you to try.

   I uses the environmental variables PETSC_DIR and PETSC_ARCH to find the 
configuration file AND use the compilers from the configuration file. It works 
for me, please let me know if you have trouble.

Re: [petsc-users] CMake error in PETSc

2019-12-08 Thread Smith, Barry F.


   There is something missing in the cmake process that is causing needed 
libraries not to be linked.

   Please email your program and your CMake stuff (files you use) so we can 
reproduce the problem and find a fix.

Re: [petsc-users] CMake error in PETSc

2019-12-08 Thread Yingjie Wu

Hi,
Thank you for your response.
This problem has not been solved. I've been reporting errors in the process
of 'make'. The test example I used comes from: /snes /example
/tutorials/ex3.c by modifying the suffix of ex3, there will be different
error messages as following. I checked a lot of DSO problems on the
Internet and installed a lot of libraries, but the error still haven't been
solved. I was wondering if I was missing any prefix during the configure of
PETSc(I use the simplest recommended installation), but there was no
problem when the program was compiled with the 'makefile' which is
recommended. Because I need some extra libraries, I have to use cmake.

Re: [petsc-users] CMake error in PETSc

It sounds like your C++ compiler is name mangling the symbol, but the
library has no mangling.
Why are you using C++.

2019-12-06 Thread Yingjie Wu

Hi,
Thank you for your email.

The error in the previous program was indeed due to the missing
"SNESSetFromOptions".
I use the /snes/example/tutorial/ex1.cpp as test case. However, I found
that some of the statements in the program were not compiled and deleted
the statements containing "MPI_Comm_size", but I don't know how to solve
this problem.

Either

  export LD_LIBRARY_PATH=$PETSC_DIR/$PETSC_ARCH/lib

or set RPATH in CMake:

  https://gitlab.kitware.com/cmake/community/wikis/doc/cmake/RPATH-handling

CMake's FindPkgConfig punts on this front (and it's sadly complicated,
but they broke their own conventions to get here).  It's been 10 years
and they've had no interest in fixing some of the problems that my
modules were created to handle.  I stopped using CMake by choice long
ago so I'd prefer to gently steer people toward something
(FindPkgConfig) that I'm not on the hook to maintain.

You can configure PETSc with --prefix=/your/standard/path, then make install.

I don't have your ex1.cpp, but presumably you didn't SNESSetFromOptions?

Re: [petsc-users] CMake error in PETSc

2019-12-05 Thread Yingjie Wu

I'm so sorry that I've ignored your previous advices.

I added a global variable that seems works:


export
LD_LIBRARY_PATH=/home/lerui/petcs-3.12.2/arch-linux2-c-debug/lib:$LD_LIBRARY_PATH


How should I make petsc in a standard position?This eliminates the need to
set global variables.

It seems that some of the options before running fit become unavailable:


mpiexec -n 1 ./example01cmke -snes_view


Options-snes _ view are not used and how should I solve this problem?


Thank you for your response.

Hi,

I installed the latest version of petsc, and compiled the example using
cmke as described above. Compilation can be done, but there is a new
problem while the program is running, as if the program could not find the
shared library libpetsc.so.3.12. How can I solve this problem? The details
are as follows:

Is your PETSc fully built/installed, or just configured?

I just tested with this simplified file

cmake_minimum_required(VERSION 2.8.11)
project(example01cmke)

add_executable(example01cmke ex1.cpp)

find_package(PkgConfig REQUIRED)
pkg_search_module(PETSC REQUIRED PETSc)

Note that you may need to set RPATH (in CMake) or export a suitable
LD_LIBRARY_PATH if your PETSc is in a non-standard location.

Hi,
I tried to use PKG to find the library file of PETSc, but there were some
errors. Because I am not very familiar with cmake, I refer to different PKG
tutorials. My CMakeList.txt is as follows. I don't know how to solve this
error message, please give me some suggestions.

3.10 should be sufficient (though we recommend upgrading).

Correct, no scripts.

Re: [petsc-users] CMake error in PETSc

2019-12-04 Thread Yingjie Wu

Thank you for your response.

I have two questions about using FindPkgConfig:


   1. Is there any requirement for petsc version using FindPkgConfig? I'm
   using an older version 3.10.1.
   2. Does the use of FindPkgConfig only require the following commands and
   does not require any scripts?

find_package(PkgConfig REQUIRED)

pkg_search_module (PETSC REQUIRED PETSc)

target_link_libraries(testapp ${PETSC_LIBRARIES})

target_link_includes(testapp ${PETSC_INCLUDE_DIRS})

Since I just came into contact with cmake, I really need some help.


Thanks,

Yingjie

This needs to be spelled PETSC_INCLUDES, as stated in FindPETSc.cmake.

These days, I usually recommend that people use

https://cmake.org/cmake/help/latest/module/FindPkgConfig.html

instead of my FindPETSc.cmake because its simpler and doesn't require
the script (which was developed before we added pkg-config support to
PETSc).

Hi,
I feel very sorry because I sent the wrong site.  I fork the module:

[petsc-users] CMake error in PETSc

2019-12-04 Thread Yingjie Wu

Dear Petsc developers
Hi,
Because I use some external library files, I want to compile the PETSc
program with CMake. I follow the library search program
https://github.com/CoolProp/CoolProp/blob/b493de51a44078e4f5bbb8712e89305fd91f8b85/CMakeLists.txt
recommended
on GitHub. And wrote a cmakelist.txt:

cmake_minimum_required(VERSION 2.8.11)
project(example01cmke)
add_executable(example01cmke ex1.cpp)
set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake/modules)
find_package(PETSc)
include_directories(${PETSC_INCLUDE_DIR})
target_link_libraries(example01cmke ${PETSC_LIBRARIES})
