Undefined reference to symbol 'CloneImageInfo' about timg

[hzeller]

So timg never refers to that symbol directly, so it might be an issue with the way GraphicsMagick++-config considers which libraries to link and probably misses one ?

If you do a git pull for a recent version of timg (changed the Makefile), you better see what GraphicsMagick++-config expands to, maybe you see a missing library ?

Output of GraphicsMagick-config :

-lGraphicsMagick++

It blames to /usr/lib64/libGraphicsMagick-Q16.so.3, but:

rpm -qf /usr/lib64/libGraphicsMagick-Q16.so.3
GraphicsMagick-1.3.25-6.fc25.x86_64

Any ideas?

Thanks in advance!

What you want to check is how the output of
GraphicsMagick++-config --ldflags --libs looks like.
On debian for instance it is

-L/usr/lib -L/usr/lib/X11 -L/usr/lib/x86_64-linux-gnu
-lGraphicsMagick++ -lGraphicsMagick -ljbig -lwebp -llcms2 -ltiff -lfreetype -ljpeg -lpng16 -lwmflite -lXext -lSM -lICE -lX11 -llzma -lbz2 -lxml2 -lz -lm -lgomp -lpthread

including all libraries that the graphics magic is depending on. If there is one missing, it might well be that you get a linking error.

If so, this looks like a misconfiguration in the Fedora package, which I suggest to figure out with them.

@hzeller

Yes, you're right

GraphicsMagick++-config --ldflags --libs

-lGraphicsMagick++

I've managed to compile with:

g++ -o timg timg.o terminal-canvas.o -lGraphicsMagick++ -lGraphicsMagick

Thanks!

adding -lGraphicsMagick solved my very similar issue attempting to compile with VisualGDB on stretch.

[TragicWarrior]

Adding -lGraphicsMagick fixed it for me. Anyone who tries to compile on Fedora 31 is going to run into this.

[hzeller]

can you file a bug with them to fix the config output?
