Compiling OpenCascade6.3.0 on Mac OS Snow Leopard Macbook Pro. How I did it

Hi, here is a short review what went wrong for me and how I solved
it. I have installed the "linux" tools from macports.

configured after doingexport CPPFLAGS=-I/opt/local/includegot error messages when compiling Draw_Window.cxx....

...

There was a problem with include statements for the preprocessor so the
order of where to find X11/Xlib.h was not good so the wrong one was taken

should have been: /opt/local/include/X11/Xlib.h

was

/System/Library/Frameworks/Tcl.framework/Versions/8.5/Headers/X11/Xlib.h

changed makefile in ./ros/adm/make/TKDraw, added -I/opt/local/include/
to DEFAULT_INCLUDES

after that it compiled until TKViewerTest, ...

g++ -DHAVE_CONFIG_H -I. -I. -I../../.. -I/System/Library/Frameworks/Tcl.framewor

../../../src/Viewer2dTest/Viewer2dTest_ViewerCommands.cxx:870: error: ‘XCheckMaskEvent’ was not declared in this scope

...

Same problem same solution...

Couldn't run DRAWEXE

...

Solution:
make uninstall
make distclean
export CXXFLAGS=-I/Developer/SDKs/MacOSX10.6.sdk/usr/X11R6/include
export LDFLAGS="-L/Developer/SDKs/MacOSX10.6.sdk/usr/X11R6/lib -lX11"
configure --x-include=/Developer/SDKs/MacOSX10.6.sdk/usr/X11R6/include/ --x-libraries=/Developer/SDKs/MacOSX10.6.sdk/usr/X11R6/lib
make
make install

end then modify make files in

./amd/make/TKDraw/

and

./amd/make/TKViewerTest/

and it compiles and DRAWEXEC starts!!!

all that is left now is to see if it was worth the trouble I went
through (I had to look at the pre processor output to catch the
mistake with the include files;)

cheers
