 |
|
Hi
Ich hatte/hab eigentlich vor ein kleines Programm zu schreiben (um c++ richtig zu erlernen) und dieses Programm sollte ein cryptsetup Frontend werden in Qt.
Nun hab ich aber beim cryptsetup Teil das Problem das ständig "undefined reference to crypt..." auftaucht.
Selbst wenn ich vom cryptsetup Project den api-test.c (kann man von git ziehen) compilieren will bekomm ich permanent undefined reference to...
Kann mir da jemand helfen oder sagen wo es hängt? oO
Test Code:
| Code: | pycoder@gentoo ~/DBus $ cat main.cpp
//#include <main.h>
#include <QtDBus>
#include <QDBusConnectionInterface>
#include <QDBusConnection>
#include <QCoreApplication>
#include <QDBusMessage>
#include <QList>
#include <QVariant>
#include <QString>
#include <QDebug>
#include <QFile>
#include <iostream>
#include <libcryptsetup.h>
int main(int argc, char *argv[]) {
QCoreApplication app(argc, argv);
// Qt Code zur überschaubarkeit entfernt hat sowieso noch nix mit cryptsetup zu tun
crypt_device *cd; // ggf = Null;
int res = crypt_init(&cd, "/dev/md0");
std::cout << res << std::endl;
return app.exec();
|
Bei meinem einfachen Code:
| Code: | pycoder@gentoo ~/DBus $ make
g++ -c -pipe -g -Wall -W -D_REENTRANT -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/usr/include/qt4/QtCore -I/usr/include/qt4/QtGui -I/usr/include/qt4 -I/usr/include/qt4/QtDBus -I. -I. -o main.o main.cpp
g++ -Wl,-rpath,/usr/lib64/qt4 -o DBus main.o -L/usr/lib64/qt4 -lQtDBus -L/usr/lib64 -L/usr/lib64/qt4 -lQtXml -lQtGui -L/usr/X11R6/lib -lQtCore -lgthread-2.0 -lrt -lglib-2.0 -lpthread
main.o: In function `main':
/home/pycoder/DBus/main.cpp:58: undefined reference to `crypt_init'
collect2: ld gab 1 als Ende-Status zurück
make: *** [DBus] Fehler 1

Beim api-test.c vom cryptsetup git:
| Code: | gentoo tests # gcc -o api-test.out api-test.c
