The Xcode for mac is generated.
But there is some error when compiling :

STEPFile.h "STEPFile.h:198:64: Use 'template' keyword to treat 'To' as a dependent template name"

That is weird. Can you post the verbose compile console output (gcc -I./ -L./ STEPFileReader.cpp -o STEPFileReader.o bla bla) that SCons and CMake use to compile STEPFileReader.cpp so we can compare them? It would make it easier to fix the error if I could understand what CMake do different from SCons.

I don't have errors with Assimp when building with Scons, but maybe we don't use the same version, did you update the Assimp lib ?

Maybe missing the flags "ASSIMP_BUILD_BOOST_WORKAROUND ASSIMP_BUILD_NO_OWN_ZLIB" ?

The code is identical to SVN revision 220, I haven't updated anything. The flags ASSIMP_BUILD_BOOST_WORKAROUND and ASSIMP_BUILD_NO_OWN_ZLIB is being defined in 3rdparty/assimp/CMakeLists.txt.

Additionally (but not related to the previous error), I didn't see the flag :
"M_PACKAGE_WRITABLE" for maratisEditor (not needed for the player)

Yup. That was an ommision by me. It is fixed now.

I'm also not sure the runpath search path is defined (depending on the dylib installation path) but should be "@rpath"
or "@executable_path/../Frameworks @loader_path/../Frameworks"

I've gone through and tried to fix all rpaths. Don't know if I did them right.

With the ios option it stops before generating the xcode project :

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
OPENGL_LIBRARY
    linked by target "MaratisApp" in directory /Users/anaelseghezzi/Desktop/Maratis-ios/M/Additional/iOS

Ok, that is the build system not finding OpenGLES, should probably add a separate OPENGLES_LIBRARY variable instead of reusing the OpenGL one so that the error become more obvious. I have now added better checks.

It's a bit frustrating for me not to have access to a Mac so I can catch all these stupid mistakes myself... wink

I just went to the wiki just now, you changed that Dahnielson? If so, it looks nice!

I think all the pages need a bit of reformatting. I haven't added anything in a while, trying to get stuff to work first.

Good to have you here also.

Yes, I reorganized and styled it a bit to make it clearer. I started to add some templates so that common stuff can be styled much easier at one place and making writing good looking wiki pages much simpler.

Re: CMake build system

Hi !

I should look again to be sure, but I didn't find the flags "ASSIMP_BUILD_BOOST_WORKAROUND ASSIMP_BUILD_NO_OWN_ZLIB" anywhere in the xcode project, or I missed it or it didn't get generated ?

Re: CMake build system

Btw, I realized that I tried to include the CMake toolchain files the wrong way (when I played around with an Android build). Updated the instructions for iOS:

iOS
---

To generate an Xcode project for building Maratis for iOS, peform the following
steps to create a build directory outside of the source tree:

  mkdir Build
  cd Build
  cmake -G XCode -DCMAKE_TOOLCHAIN_FILE=../Maratis/CMake/Toolchains/iOS.cmake \
     ../Maratis

Assuming the Maratis source directory resides in the same top directory. The
build require that the Xcode generator is used or it will protest with a fatal
error and quit

Have you tried create a new build directory to run cmake completely fresh in? Yes, I know it's a solution similar to "Have you tried to turn your computer on and off?" wink

If that doesn't work, can you try replacing

ADD_DEFINITIONS(
  -DASSIMP_BUILD_BOOST_WORKAROUND
  -DASSIMP_BUILD_NO_OWN_ZLIB
)

with

SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -DASSIMP_BUILD_BOOST_WORKAROUND -DASSIMP_BUILD_NO_OWN_ZLIB")
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DASSIMP_BUILD_BOOST_WORKAROUND -DASSIMP_BUILD_NO_OWN_ZLIB")

and see if the flags are picked up?

Re: CMake build system

Actually, I checked the xcode again and the flag is there, so it's not that.

I checked the settings and tried different fixes but I don't understand what is the problem,
it might be an issue with the Clang compiler or with c++11 standard, but if I switch to gcc there is some different errors,
or it's a dependency problem.

Assimp code is not very attractive, specially to debug.

I will check deeper, but I need to go to Paris for some work, till Saturday,
so I'll come back to you later when I'm back home.

Re: CMake build system

Hi,

I fixed some compilation errors related to CLANG and OSX Maverick : https://code.google.com/p/maratis/source/detail?r=223
for the current Maratis svn version and for your cmake version.

Now with cmake/xcode, when compiling I just have some errors with DevIL,
first I found that the header search paths where apparently missing, but sill something is wrong.

Re: CMake build system

Hi,

I managed to build your version on linux,
the file "config_types.h" was missing in libogg, but it was easy to correct manually.

But after calling make install the application is not finding libMCore.so, there is probably a problem with the rpaths.

Re: CMake build system

ok it works by adding "$ORIGIN/" to CMAKE_INSTALL_RPATH : 

SET(CMAKE_INSTALL_RPATH "@loader_path/.;$ORIGIN/")"
