Hi Is it possible to compile ftgles on raspberry I have try the normal build but the header include seems is not compatible with RPi one's thanks

Here's what I did to make it work.

In ftgles/src/Makefile.am there are some files missing. Add to the line with ftglyph_sources =

    FTGlyph/FTPixmapGlyph.cpp \
    FTGlyph/FTPixmapGlyphImpl.h \
    FTGlyph/FTPolygonGlyph.cpp \
    FTGlyph/FTPolygonGlyphImpl.h \

Add to the line ftfont_sources =

    FTFont/FTPixmapFont.cpp \
    FTFont/FTPixmapFontImpl.h \
    FTFont/FTPolygonFont.cpp \
    FTFont/FTPolygonFontImpl.h \

We need to include OpenGLES headers:

$ ./configure --includedir=/opt/vc/include --prefix=/usr/local --with-gnu-ld --without-x --with-ft-prefix=/usr

This will actually install the ftgles headers under /opt/vc/include/FTGL (which is not what I wanted, but move them afterwards).

$ make -j 4

There will be some compiler errors because file OpenGLES/ES1/gl.h can not be found. Edit the source file and change it to GLES/gl.h

This will build and work for OpenGLES 1. I did not try OpenGLES 2.
