Libbpg-0.9.7 kann nicht für BPG (Better Portable Graphics) unter Ubuntu 14.04 kompiliert werden

Obs .: Meine Vermutung ist, dass ich nicht etwas im Makefile setze oder die Arbeitspakete SDL-devel und SDL_image-devel verwende, die zuvor installiert werden sollen. Eigentlich installiere ich "libsdl2-image-2.0-0" und "libsdl2-image-dev" aus den Repositorys ... Die Readme-Datei besagt jedoch, dass diese nur für den BPGviewer benötigt werden:

(# Compile bpgview (SDL and SDL_image libraries needed) #USE_BPGVIEW=y)

OBS.1: Ich habe gerade folgendes gefunden: https://unix.stackexchange.com/questions/181735/how-to-install-bpg-better-portable-graphics-on-linux-mint-17

libbpg hängt von Version 1.6 der PNG-Bibliothek ab, die mit apt-get unter Linux Mint 17 nicht installiert werden kann. Diese Bibliothek ist nicht mit libpng12 kompatibel und muss vom Quellcode aus installiert werden (ich habe Version 1.6.16 verwendet).

Nun, ich versuche, libbpg-0.9.7 nach der Readme-Datei zu vereinfachen:

2) Compilation and Installation Notes -------------------------------------  2.1) Linux ----------  - Edit the Makefile to change the compile options (the default compile options should be OK). Type 'make' to compile and 'make install' to install the compiled binaries.  - Use 'make -j N' where N is the number of CPU cores to compile faster.  - The following packages must be installed: SDL-devel SDL_image-devel yasm. It is recommended to use yasm version >= 1.3.0 to have a faster compilation. 

So:

sudo apt-get install --force-yes -y libsdl2-image-2.0-0 libsdl2-image-dev yasm sudo apt-get install -y emscripten 

Und dann:

wget http://bellard.org/bpg/libbpg-0.9.7.tar.gz tar xzf libbpg-0.9.7.tar.gz cd libbpg-0.9.7/ make 

Es funktioniert jedoch nicht:
