SDL_ttf sometimes can't be rendered to image

Hi, in my application I used SDL_ttf with FreeSansBold.ttf from KDE (I
think). The funny thing is sometimes SDL_ttf can't render and make a
string surface. But if I restarted (sometimes numerous time) the
application again, it can make a surface. I used "TTF_RenderText_Solid" to
render the string. How can this be? Can anybody help me here? Thanks.

Fare thee well,
Bawenang R. P. P.

Which platform are you using?
Seems to work fine on Windows with SDL 1.2.11 and SDL_ttf 2.0.8.

I found a similar problem on Windows which I could reproduce using the
showfont test program:
http://www.libsdl.org/cgi/viewvc.cgi/trunk/SDL_ttf/showfont.c?revision=2429

If I used the -solid switch, then it would only work if the string
contained no spaces:

Ok:
showfont.exe -solid c:\WINDOWS\Fonts\arial.ttf 32 "Hello!"
Font is generally 36 big, and string is 36 big

Broken:
showfont.exe -solid c:\WINDOWS\Fonts\arial.ttf 32 "Hello World!"
Couldn't render text:

It turned out to be related to the version of freetype used. All ok with
freetype-2.1.10, above problem with freetype-2.2.1,

regards,
John.

Re: SDL_ttf sometimes can't be rendered to image

How do I know what type the freetype was?

Good question.

On Windows:
===========================================================================
it's tricky because freetype is statically linked into the
'SDL_ttf.dll'. A quick look didn't reveal any obvious freetype-related
strings.
===========================================================================

On Gentoo:
===========================================================================
$ emerge -p freetype

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U ] media-libs/freetype-2.1.10-r2 [2.1.10]

which shows my installed [version]. I need to do an Update there.

$ locate SDL_ttf.so
/usr/lib/libSDL_ttf.so

which shows where it is located.

$ ldd /usr/lib/libSDL_ttf.so
        linux-gate.so.1 =>  (0xffffe000)
        libfreetype.so.6 => /usr/lib/libfreetype.so.6 (0xb7f16000)

It is built against v2.1.10 if I remember correctly.

And the "space"-bug is fixed in their CVS according to this thread;

   http://www.mail-archive.com/freetype <at> nongnu.org/msg00802.html

So an alternate solution is to try the very latest cvs-snapshots and see if the problems are solved.
