No package 'sdl2' found

[ck86]

Tried to build the melt docker container but it fails due to missing sdl2 package.

Here are the last output lines:

checking for FFTW3... yes
checking for SDL2... no
configure: error: Package requirements (sdl2) were not met:

No package 'sdl2' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables SDL2_CFLAGS
and SDL2_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

Could "fix" it by installing libsdl2-dev, but now I am getting the following errors:

Thank you @bmatherly. Now I am getting this:

Any idea about this error? Should I provide more information?

[ddennedy]

Fun with C++ compiler errors! It looks like Movit is no longer compatible with the g++ 4.8 STL that this OS version includes. You can try FROM ubuntu:16.04 instead of 14:04.

If you have no plans to use OpenGL-based Movit with melt, then you can disable it by adding
RUN echo "ENABLE_MOVIT=0" >> /tmp/build-melt.conf

I will look into these this weekend when I have more time.

[ddennedy]

I updated the both the Dockerfile and build script to work with latest code and dependencies.

thanks @ddennedy :)
