Question

我正试图在Kubuntu Lucid的Qt Creator中使用clucene-0.9.21b和libcue-1.3.0。 此代码可编辑：

project.pro

SOURCES += main.cpp
LIBS += -lcue
INCLUDEPATH += /usr/include/libcue-1.3/libcue

的main.cpp

extern "C" {
 #include <libcue.h>
}
int main(int argc, char *argv[]) {
 return 0;
}

这是：

project.pro

SOURCES += main.cpp
LIBS += -clucene

的main.cpp

#include <CLucene.h>
int main(int argc, char *argv[]) {
 return 0;
}

但不是这个：

project.pro

SOURCES += main.cpp
LIBS += -lcue \
 -clucene
INCLUDEPATH += /usr/include/libcue-1.3/libcue

的main.cpp

extern "C" {
 #include <libcue.h>
}
#include <CLucene.h>
int main(int argc, char *argv[]) {
 return 0;
}

后者会产生以下错误：

为什么这样以及如何使其发挥作用？

Answer 1

如果换掉cue和clucene包括在附近会发生什么？这可能是包含顺序的问题，我怀疑混合c和c ++可能使包含顺序更加重要

Answer 2

好的，这次我有机会尝试一下。问题似乎是libcue在其include文件夹中有一个名为time.h的文件。因此，如果使用-I / usr / include / libcue-1.4 / libcue进行编译，那么最终会得到libcue的time.h而不是libc。

这对我有用：

extern "C" {
 #include <libcue/libcue.h>
}
#include <CLucene.h>

int main(int argc, char *argv[]) {
 return 0;
}

显然使用-I / usr / include / libcue-1.4 /编译而不是-I / usr / include / libcue-1.4 / libcue

我可以一起使用CLucene和Cue Sheet Parser吗？
