cmake port

[wmayer]

Hi Jürgen,

today I tried the cmake branch under Ubuntu. The configuration step stopped at the check for zlib. The error message is:
-- Found Xerces-C: /usr/lib/libxerces-c.so
CMake Error at CMakeLists.txt:71 (find_package):
Could not find module FindZlib.cmake or a configuration file for package
Zlib.

Adjust CMAKE_MODULE_PATH to find FindZlib.cmake or set Zlib_DIR to the
directory containing a CMake configuration file for Zlib. The file will
have one of the following names:

ZlibConfig.cmake
zlib-config.cmake



-- Configuring incomplete, errors occurred!
make: *** [cmake_check_build_system] Fehler 1


On my system there is neither a file ZLibConfig.cmake, nor zlib-config.cmake nor a FindZLib.cmake. And FindZlib.cmake is the only file that I found in the web but putting it into the cmake folder doesn't fix the problem? However, when commenting out the line find_package(Zlib REQUIRED) I don't get an error any more. Any ideas?

Second: Under Linux I need two defines for all project files: -DHAVE_STD_IOSTREAM and -DUSE_STD_IOSTREAM. For autoconf this can be done in configure.ac which creates then the file config.h where these defines are there. What is the way in cmake to do so? Can I let cmake create the config.h with the needed defines or is it possible to make global defines?


At least, after fixing one or two things I am able to build the Base and App modules.

I have solved the problems. Package names are case-sensitive so that Zlib must be rewritten to ZLIB. For the further defines I've found a way similar to autotools where a config.h can be created providing these defines. This works quite well. So, at the moment the cmake port of FreeCAD compiles completely FreeCADBase and FreeCADApp.

Hi,

What's the preferred build system for Freecad at the moment (and in the Future)? Are the CMake scripts in a usable state for building yet?

Hi,
the prefered Build system on Linux is still Autotools maintained be Werner.
But I think he also get good results with cMake allready.

On Windows the standard is still Visual Studio (Express). But I will soon switch to cMake.
