Error is returned when make

[Ririkosann]

Hi, I am a student in Japan and I am planning to use this tool in my research.
I just tried to run this tool.
I got a make compile error with fzn-gecode and compilelib as follows.
Is there any way to solve this problem?
By the way . /configure is done in any pattern.

This looks to me like the compiler cannot find Qt. I'm not sure what tools you intend to run, but try running configure like this:
./configure --disable-qt --disable-gist --disable-flatzinc
That way you eliminate many dependencies. Anyway, to get started you might as well download a pre-built Windows installer, if you need Gist and such.

By the way this repository lacks any detailed build instructions. You should have one

It might not be obvious at a quick glance, but detailed build instructions are available in the Modeling and Programming Guide, available as a PDF download from https://www.gecode.org/
