Please note that last integration to Git master has introduced porting of OCCT on last version of FTGL, 2.1.3rc5. This is a version included with most modern Linux distributions, and this change enables OCCT building with native FTGL on these systems.
Since FTGL is packaged in different way in 2.1.2 and 2.1.3, update of OCCT build tools (WOK, automake scripts on Linux, MS projects on Windows) is required. Please download updated WOK (Windows and Linux only) from Resources page, and rebuild.
For Windows users, we have prepared binary archives of FTGL 2.1.3rc5 and updated FreeType library (version 2.4.10 built as dynamic library) which you can find here.
Building OCCT with previously supported versions of FTGL 2.1.2 and FreeType 2.3.7 should still be possible. On Linux, this should be supported properly by automake scripts. On Windows, use of FTGL 2.1.2 requires that FreeType is rebuilt as dynamic library (which in turn requires rebuild of FTGL); in addition, pre-processor macro HAVE_FTGL_UPPERCASE must be defined during compilation of TKOpenGL. For building OCCT by MS Visual Studio, this macro can be added to variable CSF_DEFINES in env.bat (generated by WOK). For building by WOK, this macro should be defined in WOK EDL files.
Please feel free to comment on this change in this forum thread.
