CLOCKS_PER_SEC, отсутствующий двоичный оператор перед токеном ... [NFIQ 2.0]

Question

Я пытаюсь скомпилировать Исходный код NFIQ 2.0, следуя official guide. На последнем этапе сборки я получаю следующую ошибку.

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

Вот информация о GCC версии настоящего

gcc -v 
Using built-in specs.

и здесь является информация убунту версия

uname -r

Что является причиной проблемы, и может ли она быть решена используя другой компилятор? Вот полный лог сборки подпиточной команды

Answer 1

Библиотека NFIQ есть ошибка здесь.

Предполагается, что CLOCKS_PER_SEC является константой макроса, которая может использоваться в директивах препроцессора, таких как #if, но это не так! It expands, in an implementation-defined way, to some expression & hellip; и в GCC 6.3 по крайней мере (и, видимо, ваша версия тоже), что выражение ((clock_t)1000000). This expression will not work in a preprocessor directive.

Возможно, авторы NFIQ протестировали его только в Visual Studio и, возможно, Visual Studio , так получилось, чтобы развернуть этот макрос в базовый литерал. Или, может быть, они вообще не испытывали.

К сожалению, для этого нет легкого решения. Им придется прекратить использование CLOCKS_PER_SEC в директиве препроцессора вообще, но могут ли они легко достичь того же самого с фактическим кодом на C++, которого я не знаю. Определенно один поднять с авторами.
