Doesn't compile

Sounds like VTFLib13.so is missing a dependency. I am not sure what that is.

Unfortunately I'm not supporting this software anymore, sorry!

[Yepoleb]

It's a bug in VTFLib. I fixed it in this PR: panzi/VTFLib#7

[TamaMcGlinn]

Thanks Yepoleb. It hasn't solved the issue for me, just changed the error to an ImageMagick problem - the underlying issue in this project is of not specifying the dependencies:

vtf2tga.cpp:35:17: warning: variable ‘dstformat’ set but not used [-Wunused-but-set-variable]

[Yepoleb]

Can you show me the command line you used and the output of Magick++-config --version?

Edit: I just noticed tranek doesn't support this anymore, so maybe you want to try my vtf2tga inspired tool vtfconv.

[TamaMcGlinn]

Magick++-config --version gives 1.3.20
Unfortunately, vtfconv gives similar undefined references.
identify --version shows I am running ImageMagick 6.8.9-9

[Yepoleb]

What's your distribution, so I can test on it?
Maybe Magick++-config --libscan give us a clue about what's wrong. My output is -lGraphicsMagick++ -lGraphicsMagick -ljbig -lwebp -llcms2 -ltiff -lfreetype -ljpeg -lpng16 -lwmflite -lXext -lSM -lICE -lX11 -llzma -lbz2 -lxml2 -lz -lm -lgomp -lpthread.
Running ldconfig as root often magically solves linker problems for me, you could try that too.

[TamaMcGlinn]

$ Magick++-config --libs
-lGraphicsMagick++ -lGraphicsMagick -ljbig -llcms2 -ltiff -lfreetype -ljasper -ljpeg -lpng12 -lwmflite -lXext -lSM -lICE -lX11 -llzma -lbz2 -lxml2 -lz -lm -lgomp -lpthread

(Debian 9)

sudo ldconfig output nothing, and vtfconv make still runs into undefined references (despite praying)

[Yepoleb]

I just compiled vtf2tga and vtfconv on a fresh install of Debian jessie and stretch. It worked flawlessly, aside from the testing installer being constantly broken. That means the problem is most likely with your environment, but I'm fine with helping you with that. If you want you can add me on Steam, so we can talk about it there.
