In Topic: SDL2 vector graphics image loader

Also because the second example does not display the image there is no need for the glfw linking along with gl. glfw is just a window manager.

Yeah, I know, I've just been lazy hitting 'up' and changing 1s to 2s in gcc command =)

Glad everything worked.

Well this is the answer for your problem with compiling examples.

 

 

 

Go to http://www.glfw.org/, download source package.

 

Then go to console and type the following:

unzip glfw-3.1.1.zip
cd glfw-3.1.1/
mkdir curbuild && cd curbuild
cmake -G "Unix Makefiles" -DBUILD_SHARED_LIBS=ON ../
make -j3 
sudo make install

this will place your glfw headers and .so files in appropriate folders under the /usr/local ( you don't have to manually move anything ).

 

Then some part of magic takes effect.

It happened so, that nanosvg has some kind of unhealthy build system inside ( premake4 + pre-made makefiles + damaged ( ??? ) Makefile generated from premake4 ).

To build example do the following.

 

Download nanosvg as .zip from the official github page.

In your console:

 


unzip nanosvg-master.zip
cd nanosvg-master/example
cp ../src/nanosvg* .
gcc -O2 example1.c -L/usr/local/lib -lGL -lglfw -lm -Wl,-rpath=/usr/local/lib -o example1
gcc -O2 example2.c -L/usr/local/lib -lGL -lglfw -lm -Wl,-rpath=/usr/local/lib -o example2

After performing these actions I was able to launch both examples. Good luck to you, and if you need any further explanations ( i.e. makefiles, command line invocations ) feel free to ask.

 

P.S.

I don't know if GLEW is really needed here, cause I have one installed in /usr/local, but it seems that GLFW and nanosvg have no dependencies on GLEW, and I was able to compile, link and run without linking against libGLEW.so.

 

btw, my current system is Linux Mint 17.

Linux host 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2

I have Debian 8 x64 at home, if you need, I can test this there too.

I'm trying to build examples and getting the same errors.

I'll report my progress as I'll solve something.

Hi there.

This topic contains a good bit of information about your question.

In shorts: you must obtain some kind of parser/rasterizer library ( such as nanosvg ), integrate it into your project, then use it to load & rasterize SVG image & then pass the results as a pixel data to your SDL_Surface. Then you are free to go with the creation of SDL_Texture or whatever.

Neither SDL1.2 nor SDL2 have direct support for SVG.

 

P.S.

SVG format is a way far from being dead.

You can open them with anything that supports ZIP compression to see whats inside, you'll see the .dll for windows, .so for Linux and .dylib for OSX, x86 and x86_64 versions.

Wow, didn't know that, thanks.
