Victor,



    Hello and welcome to the PLIB community.  I wish you a good a
productive time here.



    The basic problem is that your program is written in C (the ".c"
extension means that GCC will use the C compiler on it) while PLIB is
written in C++.  To give one example, if you will look in the file
"sg.h" (in the "src/sg" directory) on lines 436 and 457 you will find
two definitions of the function "sgScaleVec3".  They have different
argument lists; C++ is able to distinguish between them based on the
argument lists, but C is not.



    Unfortunately there isn't much to do about it beyond redoing your
program in C++.  You may not need to redo the entire program (depending
on its size), but any part that uses a PLIB library will need to be in
C++.  You could write a wrapper function in a separate file with a
".cxx" or ".cpp" or ".cc" extension and preface your function
definitions with the string



        extern "C"



which will tell the C++ compiler that these functions will be called
from C language functions.



        - John

  Hello

  

I would like to use plib fnt to use some text, in a 3D spectral
analysis of the sound that works fine already (openGL in a SDL window).

  

The problem is : when I add the include file #include
<plib/fnt.h>,i get a huge error message that i've attached in
a file (it is so big that I don't even have the beginning in my
terminal).

  

I'm on ubuntu Maverick 10.10 64 bits; plib hab been installed from the
official packages (i've installed the libplib-dev package also);

  

I compile my program with that command : 

  

  gcc -o Spectrum `pkg-config gstreamer-0.10 --cflags --libs`
`pkg-config gtk+-2.0 --cflags --libs` `sdl-config --cflags --libs`
-lGLU -lGL -lglut -lplibfnt -lplibsg  -lglut -L/usr/X11/lib -lX11
-lXext -lXmu -lm `pkg-config jack --cflags --libs` myProgram.c

  

Before I add the fnt header,the compilation is succesfull with this
command; it's only after adding the fnt.h that problems arrive; i
understand that it is not necessary to include the sg header for it is
called by the fnt (anyway i've trid that also).

  

Could please anyone give me a clue?

  

Thank you

  

Victor
