can i use CLucene and the Cue Sheet Parser together? - c++

Question

i'm trying to use clucene-0.9.21b and libcue-1.3.0 in Qt Creator on Kubuntu Lucid. this code is compilable:
project.pro
SOURCES += main.cpp
LIBS += -lcue
INCLUDEPATH += /usr/include/libcue-1.3/libcue
main.cpp
extern "C" {
#include <libcue.h>
}
int main(int argc, char *argv[]) {
return 0;
}
so is this:
project.pro
SOURCES += main.cpp
LIBS += -clucene
main.cpp
#include <CLucene.h>
int main(int argc, char *argv[]) {
return 0;
}
but not this one:
project.pro
SOURCES += main.cpp
LIBS += -lcue \
-clucene
INCLUDEPATH += /usr/include/libcue-1.3/libcue
main.cpp
extern "C" {
#include <libcue.h>
}
#include <CLucene.h>
int main(int argc, char *argv[]) {
return 0;
}
the latter generates the following errors:

why is that and how to make it work?

Answer 1

Ok, this time I got a chance to actually try it. Problem seems to be that libcue has a file called time.h in its include folder. So if you compile with -I/usr/include/libcue-1.4/libcue then you end up with libcue's time.h instead of libc's.
This works for me:
extern "C" {
#include <libcue/libcue.h>
}
#include <CLucene.h>
int main(int argc, char *argv[]) {
return 0;
}
and obviously compiling with -I/usr/include/libcue-1.4/ instead of -I/usr/include/libcue-1.4/libcue

What happens if you swap the cue and clucene includes around? It could be a problem with include order and I suspect mixing c and c++ may make include order even more important
