Hello, trying to compile your soft I discovered that it required root priviledges and tried to install libs in /lib (which is a system directory not for installing that kind of library): g++ -c -pipe -O2 -Wall -W -D_REENTRANT -fPIC -DQT_NO_DEBUG -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. -I. -o mda.o mda.cpp rm -f libchainlink_base.so.1.0.0 libchainlink_base.so libchainlink_base.so.1 libchainlink_base.so.1.0 g++ -Wl,-O1 -shared -Wl,-soname,libchainlink_base.so.1 -o libchainlink_base.so.1.0.0 chainlink_base.o chainlink_complex.o chainlink_string.o mda.o -L/usr/lib -lQtGui -lQtCore -lpthread ln -s libchainlink_base.so.1.0.0 libchainlink_base.so ln -s libchainlink_base.so.1.0.0 libchainlink_base.so.1 ln -s libchainlink_base.so.1.0.0 libchainlink_base.so.1.0 rm -f /lib/libchainlink_base.so.1.0.0 rm -f /lib/libchainlink_base.so rm -f /lib/libchainlink_base.so.1 rm -f /lib/libchainlink_base.so.1.0 mv -f libchainlink_base.so.1.0.0 libchainlink_base.so libchainlink_base.so.1 libchainlink_base.so.1.0 /lib/ mv: cannot create regular file `/lib/libchainlink_base.so.1.0.0': Permission denied mv: cannot create symbolic link `/lib/libchainlink_base.so': Permission denied mv: cannot create symbolic link `/lib/libchainlink_base.so.1': Permission denied mv: cannot create symbolic link `/lib/libchainlink_base.so.1.0': Permission denied make[1]: [/lib/libchainlink_base.so.1.0.0] Error 1 (ignored) make[1]: Leaving directory `/tmp/chainlink/chainlink_base' Also, is ChainLink still developed ?
