Hi,

A link problem has been introduced recently with the addition of fonts.
On my linux i get the following error :

Quote:

..../upp.out/MyApps/CtrlCore/GCC.Blitz.Gui.Shared.Sse2/DrawT extX11.o: In function `_GLOBAL__sub_I__ZN3Upp13gtk_antialiasE':
DrawTextX11.cpp:(.text.startup._GLOBAL__sub_I__ZN3Upp13gtk_a ntialiasE+0x86): undefined reference to `Upp::GetFontInfoSysXft'
DrawTextX11.cpp:(.text.startup._GLOBAL__sub_I__ZN3Upp13gtk_a ntialiasE+0x90): undefined reference to `Upp::GetGlyphInfoSysXft'

When looking at the code all seems right : the variables are instanciated :

Quote:

uppsrc/Draw/FontFc.cpp(144):CommonFontInfo (*GetFontInfoSysXft)(Font font);

And extern is used to tell these vars are available in another section.

The following question comes to my mind : "extern xxx;" is a C syntax, is it allowed in C++ ????

Are you sure you have Draw package in the project?

Hi mirek,

Unfortunantly yes Sad

I wish it was so simple.

There is probably a conditionnal include problem.
I'll look into it now

Here is what I get when I compile Draw01 tutorial

OK I found what is wrong,

the flag CUSTOM_FONTSYS is present in the main.conf.h

BUT .....

If I remove it, it just comes back again.
TheIDE just adds it automatically again and again

This flag was being added by the plugin/FT_fontsys package (I had added it to my project last WE just to try and completelly forgot about it !!!)

==> the conclusion is : plugin/FT_fontsys does not work on linux

That is sort of weird, as I am compiling it several times a day, working on SDL/OpenGL backend... but will check it.

I've just done a simple test:
Added plugin/FT_fontsys to Draw01 tutorial, did a complete rebuild and got the following errors:

collect2: error: ld returned 1 exit status

I verified that the main.conf.h file for Draw01 contained : #define CUSTOM_FONTSYS

==> I'm back to my original question: is "extern xxxx" really accepted in C++ ??? or is my GCC doing me some nasty tricks ???

My GCC is the following :

OK, now I understand the problem: FT_FontSys replaces font handling in Draw, but CtrlCore with GTK or X11 backend requests some specific routines linking it to Xft. Which means you cannot use FT_FontSys with GTK nor X11 backend...
