CLOCKS_PER_SEC, missing binary operator before token... [NFIQ 2.0]

I'm trying to compile NFIQ 2.0 source code by following the official guide. In the final build step I get the following error.

FRFXLLCreateLibraryContext.cpp:72:5: error: missing binary operator before token "1000000"
 #if CLOCKS_PER_SEC == 1000
     ^
<builtin>: recipe for target 'FRFXLLCreateLibraryContext.o' failed

Here is information about the gcc version present

gcc -v
Using built-in specs.

What is causing the problem, and could it be solved by using a different compiler? Here is the full build log of make command

The NFIQ library has a bug here.

It assumes that CLOCKS_PER_SEC is a macro constant that can be used in preprocessor directives like #if, but it isn't! It expands, in an implementation-defined way, to some expression… and in GCC 6.3 at least (and apparently your version too) that expression is ((clock_t)1000000). This expression will not work in a preprocessor directive.

Maybe the NFIQ authors only tested it in Visual Studio, and maybe Visual Studio just so happens to expand that macro to a basic literal. Or, maybe, they didn't test it at all.

Unfortunately there's no easy fix for that. They'd have to stop using CLOCKS_PER_SEC in a preprocessor directive altogether, but whether they can easily achieve the same thing with actual C++ code I don't know. Definitely one to raise with the authors.
