Does this project support building on Windows with msys2/gcc?

Hi, I comes from this wxWidgets forum discussion: Showing a VTK view as a wxPanel - wxWidgets Discussion Forum

Basically, I see in msys2, the vtk library is supplied: Package: mingw-w64-x86_64-vtk - MSYS2 Packages

Also, the wxWidgets library is also supplied: Base Package: mingw-w64-wxwidgets3.2 - MSYS2 Packages

Thanks.

Ready builds on Linux fine with gcc, so it might work on msys2. Did you try it?

Hi, Tim, thanks for the reply. I haven't tried it. In-fact, I'm not a cmake expert, it maybe hard for me to build this project. It looks like msys2 also supplied the opencl related library.

Cmake makes things very easy indeed when it all works as intended, definitely worth a try! Granted there can be more complexity when it doesn't work but I think it even helps a bit there too in most cases, I guess have a crack eh? Hopefully you'll be pleasantly surprised :)

Here is my steps: I have clone the repo in my folder: E:\code\ready, and I have mkdir build, and cd build.

In the msys2's mingw64.exe shell, I just type:

# cmake ../

In-fact, I have vtk installed, see below:

# pacman -Ss vtk
...
    Parallel Data Analysis and Visualization Application based on VTK. (mingw-w64)
mingw64/mingw-w64-x86_64-vtk 9.2.6-12 [installed]
...

It looks like some library is not found, so I try to install some libraries.

Here is the command I used, once I found a missing library, I just install it, luckily, msys2 supplies most of the libraries.

pacman -S mingw-w64-x86_64-cli11

pacman -S mingw-w64-x86_64-postgresql

pacman -S mingw-w64-x86_64-pdal

pacman -S mingw-w64-x86_64-cgns

pacman -S mingw-w64-x86_64-adios2

After that, I got the result below:

Do I need to install QT? It looks like I need wxWidgets. So, I need to disable QT?

I looked at the source file F:/msys2/mingw64/lib/cmake/vtk/VTK-vtk-module-find-packages.cmake:1543 (find_package):

if (_vtk_module_find_package_enabled)
  set(_vtk_module_find_package_required)

    set(_vtk_module_find_package_required REQUIRED)
  endif ()

    ${_vtk_module_find_package_required}

    OPTIONAL_COMPONENTS )
  if (NOT Qt6_FOUND AND _vtk_module_find_package_fail_if_not_found)
    if (NOT ${CMAKE_FIND_PACKAGE_NAME}_FIND_QUIETLY)
      message(STATUS
        "Could not find the ${CMAKE_FIND_PACKAGE_NAME} package due to a "
        "missing dependency: Qt6")
    endif ()
    set("${CMAKE_FIND_PACKAGE_NAME}_GUISupportQtQuick_FOUND" 0)
    list(APPEND "${CMAKE_FIND_PACKAGE_NAME}_GUISupportQtQuick_NOT_FOUND_MESSAGE"
      "Failed to find the Qt6 package.")
  endif ()
endif ()

I'm not sure that some libraries are needed or not.

When I looked at this page: Package: mingw-w64-x86_64-vtk - MSYS2 Packages

It mentioned that QT is only an optional library, but it looks like when the F:\msys2\mingw64\lib\cmake\vtk\VTK-vtk-module-find-packages.cmake is called from the file F:\msys2\mingw64\lib\cmake\vtk\vtk-config.cmake, there is a line:

include("${CMAKE_CURRENT_LIST_DIR}/${CMAKE_FIND_PACKAGE_NAME}-vtk-module-find-packages.cmake")

with this line, many packages will be searched by cmake, if it can't find on in VTK-vtk-module-find-packages.cmake, it just failed.

I'm not sure how to "disable" or "skip" the "QT" check in this file.

I just comment out the line 152 in the file F:\msys2\mingw64\lib\cmake\vtk\vtk-config.cmake

# include("${CMAKE_CURRENT_LIST_DIR}/${CMAKE_FIND_PACKAGE_NAME}-vtk-module-find-packages.cmake")

So, I don't see such error report, since vtk does not try to find every component.

But I still got errors:

# cmake ../

  CMakeLists.txt:466 (find_package)

-- Configuring incomplete, errors occurred!

When I looked at the ready's own cmakefile.txt, I see that it has its own FindOpenCL.cmake.

For me, I'm using the latest msys2's gcc(mingw64), and it does have a FindOpenCL.cmake. Also, I has such libraries installed in msys2

pacman -S mingw-w64-x86_64-opencl-headers
pacman -S mingw-w64-x86_64-opencl-icd

So, maybe some of the devs can help to try it, I just stalled here. Thanks.

To tweak the opencl related issue, I just comment out the line 462 of the E:\code\ready\CMakeLists.txt, this means that I don't need to use ready's own FindOpenCL script.

When I enable this line, I just need to install QT or QTQuick, which I think I don't need to build this project, otherwise I got cmake error.

Any ideas?

Hi Ollydbg, Wow, nice work getting through all of that! You definitely made progress!

I'm sorry to have led you down what now seems to be a rather difficult path (I've been down a similar way a few times myself, but in a Gentoo Linux context and there's no portage "ebuild" for Ready yet (auto-build-and-install script for Gentoo) that would make it generally very easy to build.. that reminds me I wanted to talk to some Gentoo peeps about making one!).

I'm afraid I don't have a windows environment to try building it in myself, otherwise I'd definitely have a go.

I wondered whether Qt might mainly be there because VTK needs it.. yes Ready seems to use VTK with the wxWidgets bindings so you'd think it wouldn't be needed but maybe it still needs Qt to be there for some reason? I do see that some of Ready's help-documentation-generator seems like it might use qhelpgenerator so it is probably worth getting it installed anyway I'd say (even tho it's large!).

I'd love to hear what brings you to Ready (what a bloody amazingly cool project eh?), and particularly what makes you want to build it yourself? Not trying to discourage you at all - definitely a noble goal for sure but there are prebuilt windows binaries available IIUC? (indeed if/when you do get it working it'd be great to add some notes about building Ready with mysys2/mingw to the BUILD.txt in Ready for future builders : )

Fingers crossed for the next bit! Have an ace one, Dan

I think my goal to try the project Ready is very simple. I'm a wxWidgets fan, and I would like to try a 3D library such as VTK to running in the wxWidgets' framework. I'm not a QT fan.

So, I come from the wx forum, and I see some one is discussing the combination of wxWidgets and VTK.

Also, I'm a msys2 user, and install software and packages are very easy by using the pacman command under msys2.

There are a lot of users who using msys2/gcc, so it is great if we can build Ready under msys2/gcc.
