[vtk-developers] bug 8513, updating freetype; need Windows dev to help

[Bill Lorensen]

Sean,

Sorry, I looked at the wrong VTK version. Here are the comments:

/*

VTK_FREETYPE_CHANGE this file is new for VTK.

This header file mangles all symbols exported from the freetype library.
It is included in all files while building the freetype library.  Due to
namespace pollution, no freetype headers should be included in .h files in
VTK.

The following command was used to obtain the symbol list:

nm libvtkfreetype.a |grep " [TRD] "

This is the way to recreate the whole list:

nm bin/libvtkfreetype.a |grep " [TRD] " | awk '{ print "#define "$3"
vtk_freetype_"$3 }'

In fact, you must do this on all supported platforms and merge the results,
since some symbols may be present on only some platforms.

Then alphabetise the list so that future diffs/merges work better.

Note that _fini and _init should be excluded because they are not functions
implemented by the library but are rather created by the linker and
used when the shared library is loaded/unloaded from an executable.

*/

I'm still surprised you need to do this on all platforms. But I have
not looked at freetype's internals.

Bill
