1 Building with Xcode {#occt_dev_guides__building_xcode}
4 This file describes steps to build OCCT libraries from a complete source package
5 on Mac OS X with **Xcode**.
7 If you build OCCT from bare sources (as in Git repository) or do some
8 changes affecting CDL files, you need to use WOK to re-generate header files
9 and build scripts / projects. See \ref occt_dev_guides__building_wok for instructions.
11 Before building OCCT, you need to install the required third-party libraries; see
12 paragraph 1 of \ref occt_dev_guides__building for details.
14 1. Add paths to the mandatory 3rd-party products (**Tcl/Tk** and **FreeType**)
15 in file *custom.sh* located in <i>\<OCCT_ROOT_DIR\> </i>. For this:
17 1.1. Add paths to the includes in variable *CSF_OPT_INC*;
19 1.2. Add paths to the binary libraries in variable *CSF_OPT_LIB64*;
21 All paths should be separated by ":" symbol.
23 2. Add paths to the optional 3rd-party libraries (**TBB, gl2ps** and **FreeImage**)
24 in the aforementioned environment variables *CSF_OPT_INC* and *CSF_OPT_LIB64* from file *custom.sh*.
26 If you want to build OCCT without the optional libraries perform the following steps:
28 2.1 Disable unnecessary library in *custom.sh* by setting the corresponding
29 variable <i>HAVE_<LIBRARY_NAME></i> to *false*.
31 export HAVE_GL2PS=false
33 2.2 Remove this library from Project navigator in Xcode for each project that
34 uses it: choose the required project, right click on the unnecessary
35 library and select **Delete** button.
37 3. Open Terminal application.
39 4. Enter <i>\<OCCT_ROOT_DIR\></i>:
43 5. To start **Xcode**, run command <i>/xcode.sh</i>
45 6. To build a certain toolkit, select it in **Scheme** drop-down list in Xcode
46 toolbar, press **Product** in the menu and click **Build** button.
48 To build the entire OCCT, create a new empty project (select **File ->
49 New -> Project -> "Empty project** in the menu. Input the project name,
50 e.g. *OCCT*, click **Next** and **Create** buttons). Drag and drop the *OCCT*
51 folder in the created *OCCT* project in the Project navigator. Select
52 **File -> New -> Target -> Aggregate** in the menu. Enter the project name
53 (e.g. <i>OCCT</i>) and click **Finish**. The **Build Phases** tab will open.
54 Click "+" button to add the necessary toolkits to the target project.
55 It is possible to select all toolkits by pressing **Command+A** combination.
57 To start *DRAWEXE*, which has been built with Xcode on Mac OS X, perform the following steps:
59 1.Open Terminal application
61 2.Enter <i>\<OCCT_ROOT_DIR\></i>:
70 Option *d* is used if OCCT has been built in **Debug** mode.
