Why do I get this error msg: texture-font.c:(.text+0x10d): undefined reference to `FT_Init_FreeType'

[l...@sr-research.com]

Hi,

    I build libfreetype-gl.a on 64bit ubuntu, by doing:
   

$cmake -Dfreetype-gl_BUILD_DEMOS=OFF -DFREETYPE-GLXX_BUILD_DEMO=OFF -DINTERNAL_FREETYPE=OFF -DINTERNAL_GLEW=OFF -DGLUT_INCLUDE_DIR=~/li/bin

then make

When I use libfreetype-gl.a in my project, I get error saying:

libftgl64.a(texture-font.c.o): In function `texture_font_load_face':
texture-font.c:(.text+0x10d): undefined reference to `FT_Init_FreeType'

texture-font.c:(.text+0x18b): undefined reference to `FT_New_Face'
texture-font.c:(.text+0x1f9): undefined reference to `FT_Done_FreeType'
texture-font.c:(.text+0x217): undefined reference to `FT_Select_Charmap'
texture-font.c:(.text+0x285): undefined reference to `FT_Done_Face'
texture-font.c:(.text+0x294): undefined reference to `FT_Done_FreeType'
texture-font.c:(.text+0x2e4): undefined reference to `FT_Set_Char_Size'
texture-font.c:(.text+0x352): undefined reference to `FT_Done_Face'
...

Does anyone know why I get these error messages and how to fix it? Thanks a lot!

Most probably the freetype library is missing.
Did you check the last version at https://github.com/rougier/freetype-gl ?

If so, can you open an issue on github ?

Hi, 

    Thank you very much for your reply. I think it is probably my side problem because I made a 32bit dynamic version before and it works.

    for freetype library, is it included in libfreetype-gl or I should link it seperately say, add -lfreetype? Thanks. 

     By the way, do you know how to build dynamic library instead of a static freetype-gl? Thanks a lot!

It very much depend on your system I think. You can have a look at the new CMakefile to check if there is an option. If not, just open an issue on github, I'm pretty sure someone already solved the problem.
