CMake HDF5 definition error during building FreeCAD on Win 7 using msys2 MinGW 64

[Yasser]

Hello,
I'm using msys2 (MinGW 64) on Windows 7 sp1 to compile and build FreeCAD 0.20 Beta1
i downloaded the source code then started to build
but,
i faced two errors till now one i solved (i will talk about it later) and the other not yet
As described in the picture
hdf5 library needs to be defined to cmake but how ??
i guess the library of hdf5 exists in MinGW/bin ??
>>>>>>>>>>>>>>>>>>>>> here is the error

Code: Select all

CMake Error at cMake/FreeCAD_Helpers/SetupSalomeSMESH.cmake:79 (find_package):
  Could not find a package configuration file provided by "HDF5" with any of
  the following names:

    HDF5Config.cmake
    hdf5-config.cmake

  Add the installation prefix of "HDF5" to CMAKE_PREFIX_PATH or set
  "HDF5_DIR" to a directory containing one of the above files.  If "HDF5"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  CMakeLists.txt:58 (SetupSalomeSMESH)

I'm not familiar with Windows compilation but wehre did you get the libraries from? I think @chennes had some experience with mingw compilation

I did install the libraries as mentioned in freecad msys2 installation page by command "pacman -S" then the module name!!
there are a full list of libraries and its dependencies.
the link of the page:

and is hdf5 installed? Try installing mingw-w64-x86_64-hdf5

and is hdf5 installed? Try installing mingw-w64-x86_64-hdf5

It's already installed when i installed msys2
the problem is that cmake can't see the hdf5 directory
the hdf5 exist in the libpack
so i added this line to CMakeList.txt

Code: Select all

list(APPEND CMAKE_PREFIX_PATH "${CMAKE_CURRENT_SOURCE_DIR}/LibPack") 

and that solved the problem temporarily but other issues comes!!
thank you for your concerning.

so i added this line to CMakeList.txt

Awesome! Can you update the wiki page then?

[adrianinsaval]

Is the libpack meant to be used for mingw compilation? I thought that was for msvc

Before any updates, Would you install msys2 with mingw 64 on windows and let us walk through this jungle together

True, i couldn't configure the hdf5 in MinGW_64 so i tried the LibPack, this is why i said "Temporarily", just to find out next issues.
i choosed msys2 MinGW 64 to compile freecad because that will save time when compiling at Linux later.

[Yasser]

This is the final modification result without using LibPack
hdf5 configuration file exist in this directory so i added it to the path list
and the cmake goes flawless in cmake ../freecad without errors or warnings
if i succeeded in building freecad i'll post full detail about how it's done for the beginners.
next step cmake --build ./ is full of trouble

Code: Select all

list(APPEND CMAKE_PREFIX_PATH "C:/msys64/mingw64/lib/cmake")
