Building with Xcode

This file describes steps to build OCCT libraries from complete source package on Mac OS X with Xcode.

If you are building OCCT from bare sources (as in Git repository), or do some changes affecting CDL files, you need to use WOK to re-generate header files and build scripts / projects. See Using WOK for instructions.

Before building OCCT, you need to install required third-party libraries; see paragraph 1 of Building OCCT from sources for details.

1. Add paths to the mandatory 3rd-party products (Tcl/Tk and FreeType) in file custom.sh located in <OCCT_ROOT_DIR>. For this:

   1.1. Add paths to the includes in variable "CSF_OPT_INC";

   1.2. Add paths to the binary libraries in variable "CSF_OPT_LIB64";

   All paths should be separated by ":" symbol.

2. Add paths to the optional 3rd-party libraries (TBB, gl2ps and FreeImage) in the aforementioned environment variables "CSF_OPT_INC" and "CSF_OPT_LIB64" from file custom.sh.

   If you want to build OCCT without the optional libraries perform the following steps:

   2.1 Disable unnecessary library in custom.sh by setting the corresponding variable HAVE_<LIBRARY_NAME> to "false".

   export HAVE_GL2PS=false

   2.2 Remove this library from Project navigator in Xcode for each project that uses it: choose the required project, right click on the unnecessary library and select "Delete" button.

3. Open Terminal application.

4. Enter <OCCT_ROOT_DIR>:

   cd <OCCT_ROOT_DIR>

5. To start Xcode, run the command /xcode.sh

6. To build a certain toolkit, select it in "Scheme" drop-down list in Xcode toolbar, press "Product" in the menu and click "Build" button.

   To build the entire OCCT, create a new empty project (select "File -> New -> Project -> "Empty project" in the menu. Input the project name, e.g. "OCCT", click "Next" and "Create" buttons). Drag and drop the "OCCT" folder in the created "OCCT" project in the Project navigator. Select "File -> New -> Target -> Aggregate" in the menu. Enter the project name (e.g. "OCCT") and click "Finish". The "Build Phases" tab will open. Click "+" button to add the necessary toolkits to the target project. It is possible to select all toolkits by pressing "Command+A" combination.

To start DRAWEXE, which has been built with Xcode on Mac OS X, perform the following steps:

1. Open Terminal application

2. Enter <OCCT_ROOT_DIR>:

   cd <OCCT_ROOT_DIR>

3. Run script

   ./draw_cbp.sh xcd [d]

   Option "d" is used if OCCT has been built in Debug mode.
