t4kcommon's Introduction

Tux4Kids - Open source education software for children

About Tux4Kids

Tux4Kids is an international group of volunteers developing high-quality software for kids, with the goal of combining fun and learning into an irresistable package.

Our software is free: you can download it for use at home or onto hundreds of computers in a school. We support all major platforms, including Windows, Macintosh, and Linux/Unix. Our programs are used by people around the globe, and they have been translated into dozens of different languages. As open-source software, these programs can be freely extended or customized, and they are supported by active communities of volunteer developers.

Whether you're a parent, a teacher, or a kid, give Tux4Kids software a try!

Main Projects

Tux Paint

Tux Paint is a drawing program for children as young as 3 years old, containing Tux the Linux penguin, many goofy sound effects, and a large assortment of prepackaged imagery and special effect tools.

Tux, of Math Command

Tux, of Math Command lets kids hone their arithmetic skills while they defend penguins from incoming comets, or offers them a chance to explore the asteroid belt with only their factoring abilities to bring them through safely!

Tux Typing

In Tux Typing, Tux the penguin is hungry, and loves to eat fish. But Tux can only catch the fish if you type the right letters in time! Can you help Tux?

Other projects

There are also a number of in-progress projects that can be found on our GitHub project page.

t4kcommon's Issues

New release required

Dear Devs, I am maintaining an Operating system named Accessible-Coconut which is accessible for visually impaired persons. We have many fans from various countries, But they also need this kind of accessible games in their normal Debian based systems. So we need to debianize new Tuxtype, Tuxmath and T4K-Common followed by a release. Please do the needful.

Is that intended? Is it a compiler version thingy?

A number of libraries are not linked - unresolved symbols

The following libraries should be added into CMake files: SDL_net, cairo, libiconv, librsvg and others.

Building without SDLPango doesn't seem to work

I've been trying (and failing) to build t4kcommon without SDLPango.

Here's what I tried (trying to follow INSTALL when possible):

Make ended with the following errors:

/usr/bin/ld: ./.libs/libt4k_common.so: undefined reference toTTF_OpenFont'
/usr/bin/ld: ./.libs/libt4k_common.so: undefined reference to TTF_CloseFont' /usr/bin/ld: ./.libs/libt4k_common.so: undefined reference to TTF_RenderUTF8_Blended'
/usr/bin/ld: ./.libs/libt4k_common.so: undefined reference to TTF_SizeUTF8' /usr/bin/ld: ./.libs/libt4k_common.so: undefined reference to TTF_GlyphMetrics'
/usr/bin/ld: ./.libs/libt4k_common.so: undefined reference to TTF_FontAscent' /usr/bin/ld: ./.libs/libt4k_common.so: undefined reference to TTF_Init'
/usr/bin/ld: ./.libs/libt4k_common.so: undefined reference to TTF_Quit'

build failure with a newer PNG library (version 1.5.0 and up according to the docs)

info_ptr is no longer defined globally. The following may fix the compile error occuring in src/t4k_loaders.c:

-               info_ptr->width = surf->w;
-               info_ptr->height = surf->h;
-               info_ptr->bit_depth = 8;
-               info_ptr->color_type = PNG_COLOR_TYPE_RGB_ALPHA;
-               info_ptr->interlace_type = 1;
-               info_ptr->valid = 0;    /* will be updated by various png_set_FOO() functions */
+               png_set_IHDR(png_ptr, info_ptr,
+                                        surf->w,

No texts in TuxMath and TuxType Arch Linux

Hi,

TuxMath does not render texts in menus nor in game. It seems a problem with SDL.

I've submitted a fix to address it here:

frealgagu/archlinux.t4kcommon#1

I am no expert in SDL: the only thing I've done is return white_letters instead of bg in T4K_BlackOutline:

t4kcommon/src/t4k_sdl.c

Lines 1444 to 1454 in f36ec17

    
           SDL_BlitSurface(white_letters, NULL, bg, &dstrect); 
        
           SDL_FreeSurface(white_letters); 
        
           /* --- Convert to the screen format for quicker blits --- */ 
        
           SDL_SetColorKey(bg, SDL_SRCCOLORKEY|SDL_RLEACCEL, color_key); 
        
           out = SDL_DisplayFormatAlpha(bg); 
        
           SDL_FreeSurface(bg); 
        
           DEBUGMSG(debug_sdl, "\nLeaving T4K_BlackOutline(): \n"); 
        
           return out;

Best!!

linebreak CMakeLists on Mac

Compile definitions in src/linebreak/CMakeLists.txt seems to be without value. The following fixes makefile generation:

-set_directory_properties(PROPERTIES COMPILE_DEFINITIONS
+set_directory_properties(PROPERTIES #COMPILE_DEFINITIONS
        LOCALEDIR='\"${LOCALE_DIR}\"'           
        LOCALE_ALIAS_PATH='\"${LOCALE_DIR}\"'
        LIBDIR='\"${TOP_SRC_DIR}\"'

libspeechd.h: no such file or directory

Trying to build on Arch Linux, I get an error stating that libspeechd.h cannot be found. I have speech-dispatcher installed, and libspeechd.h is located at /usr/include/speech-dispatcher/libspeechd.h. However, even adding the exact location to my CFLAGS, the file still cannot be found, so t4kcommon fails to build. This seems to affect T least Tuxtype as well.

This despite the fact that the configure script has determined how to link with libiconv:

checking for iconv... yes
checking for working iconv... yes
checking how to link with libiconv... -liconv

Yet it has not actually added -liconv to the link flags. If I manually add -liconv to LDFLAGS when configuring then it does link successfully but the build system should do that itself.
