Also could you provide CMakeCache.txt and CMakeFiles/CMakeError.log to see what gone wrong...
There's no url to the contents of the libacks, per sey.On Windows it's not necessary to have a compiled NETGEN. From the the libpack we use nglib. I believe there is a .dll in\bin, plus /netgen + /lib and + /include sub-directories. I'll try to make this understandable and post back.

It's true only if package provides version information somehow, e.g. via pkg-config
Ok, on debian based systems, you can query version information for each officially installed package with dpkg:

Code: Select all

dpkg -l | grep <package-name>
A complete commandline to get the version of developer library of i.e. libavcodec looks like:

Code: Select all

dpkg -l | grep libavcodec-dev | head -1 | awk '{ print $3; }'
... by the way: netgen provides version informations in CMakeLists.txt in root directory

Code: Select all

if(NOT CMAKE_BUILD_TYPE)
    set(CMAKE_BUILD_TYPE "RelWithDebInfo" CACHE STRING INTERNAL)
endif(NOT CMAKE_BUILD_TYPE)

cmake_minimum_required(VERSION 2.8.9)
project(Netgen)
set(NETGEN_VERSION_MAJOR 6)
set(NETGEN_VERSION_MINOR 1)
set(NETGEN_VERSION "${NETGEN_VERSION_MAJOR}.${NETGEN_VERSION_MINOR}-dev")
set(PACKAGE_VERSION "${NETGEN_VERSION}")
... so version information could be obtained with grep

Sad to say - netgens executable is a poor one. It does not support the standard version query like "netgen --version"

sgrogan, thanks for your input... It will be helpfull...

Ok, There is one pretty easy to fix:

Code: Select all

It just requires zlib... don't know if it will require link to the dll, but yet another find_package() should fix this issue... But I suppose it will break on the the second one issue like two other tests.

But I don't really know what to do with this one:

can somebody point me out whay should I include/define to make the /MDd happy? may be it will be enough to just define _AFXDLL? may it be empty?
I suppose /MDd should be there itself because there are other tests built well with it...

Code: Select all

//Path to a library.
NETGEN_LIBRARY_mesh:FILEPATH=NETGEN_LIBRARY_mesh-NOTFOUND

//Path to a library.
NETGEN_LIBRARY_occ:FILEPATH=NETGEN_LIBRARY_occ-NOTFOUND
Are there any *{occ,mesh}.{lib,dll} in your netgen distribution? Is it version 5+?

According to the build script it should be 5.1
https://github.com/peterl94/clbundler-f ... /netgen.py

In
LibPack/bin/ there is nglib.dll

In
Libpack/include/netgen/csg
Libpack/include/netgen/meshing
Libpack/include/netgen/occ
etc.
These directories contain only header files (.hpp)

In
Libpack/lib/ there is nglib.lib

Sorry, that I haven't replied for a while...
I can't fix the test code compilation on MSVC, so I've just disabled it... that should be enough to make it work... please check...

django013 wrote:... by the way: netgen provides version informations in CMakeLists.txt in root directory
first, it's only for version six, which is not released yet (at least there is no stable release), 5.x still uses autotools, secondly the CMakeLists.txt is not being installed to the system... so unless upstream will provide it's own FindNETGEN module it's useless...

even if it were, we couldn't lay on that this executable is installed on the building system due to freecad doesn't depends upon netgen itself, but only on the nglib...

Thanks, for testing...
I'll wait for some time if there will be some positive or negative feedbacks from mingw or mac users... And if there won't be any I'll pull-requst...

Could you postpone this until Friday next week or so?

I can't (was: can) wait to start building FreeCAD rpm packages from the master branch for fedora witn netgen switched on 8-)

Edit: Thanks wmayer for catching the typo!
