I ran into the same problem. I use the development version of Nim. I found that I could run the example if I used 1.4.8 instead.

In fact I meant to investigate if this is a bug in the development version or not.

It may have something to do with symbol resolution. There is the tuple in sdl2 named Color and then there is a constructor in color named Color.

Also, I had some issues linking SDL2 on my macOS system. I have a rather old system so your mileage may vary. I ended downloading the frameworks and attaching them with:

for dmg in SDL2*.dmg; do hdiutil attach $dmg; done

I then created a config.nims file containing this:

--define:SDL_Static
{.passL: "-rpath /Volumes/SDL2".}
{.passL: "-rpath /Volumes/SDL2_image".}
{.passL: "-rpath /Volumes/SDL2_ttf".}
{.passL: "-rpath /Volumes/SDL2_mixer".}
{.passL: "-F /Volumes/SDL2".}
{.passL: "-F /Volumes/SDL2_image".}
{.passL: "-F /Volumes/SDL2_ttf".}
{.passL: "-F /Volumes/SDL2_mixer".}
{.passL: "-framework SDL2".}
{.passL: "-framework SDL2_image".}
{.passL: "-framework SDL2_ttf".}
{.passL: "-framework SDL2_mixer".}

This will fix the compilation error:

I'm getting same issue on Bohdi Linux (Ubuntu 20.0)

I will try the patch first.

[nixfreak]

diff --git a/src/nodesnim/core/font.nim b/src/nodesnim/core/font.nim

I really confused are you saying create two directories a and b ? also do you mean git-diff ?

[quantimnot]

that was a diff created with git diff

[nixfreak]

Same issue using nightly also

Ok switched to 1.4.8 and it compiled just fine.

After changing to stable 1.4.8 every compiles fine now.
