crach when compil

hello
excuse me for my bad english
when i compil Librecad 2.0 (GIT), i have this message :

asciifile.cpp:45:6: attention : unused parameter ‘cmd’ [-Wunused-parameter]
asciifile.cpp:664:1: erreur: inconsistent user-defined literal suffixes ‘QT_VERSION_STR’ and ‘QPLUGIN_DEBUG_STR’ in string literal
asciifile.cpp:664:1: erreur: unable to find string literal operator ‘operator"" QT_VERSION_STR’
asciifile.cpp: In function ‘const char* qt_plugin_query_verification_data()’:
asciifile.cpp:664:1: attention : contrôle a atteint la fin non void de la fonction [-Wreturn-type]
make[2]: *** [../../generated/plugin/asciifile/obj/asciifile.o] Erreur 1

make[1] : on quitte le répertoire « /home/thierry/git/LibreCAD/plugins »
make: *** [sub-plugins-make_default-ordered] Erreur 2

i have distrib zenwalk snapshot 7.2, kernel 3.2.5, QT 4.7.0_7abde40 , GCC 4.7.0,

i make link qt and qt4 to qt4.7.0_abde40 in /usr/lib
i input in .zshrc export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib/qt/lib/
when i make "printenv" :
LD_LIBRARY_PATH=:/usr/lib/qt4/lib/:/usr/lib/qt/lib/
QT4DIR=/usr/lib/qt
QT3DIR=/usr/lib/qt-4.7.0_7abde40
CPLUS_INCLUDE_PATH=/usr/lib/qt/include:/usr/lib/qt-4.7.0_7abde40/include
i dont see where is the probleme.
thanks

hello
I found my problem on this page,
https://bugreports.qt-project.org/browse/QTBUG-22847?focusedCommentId=168644
page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel
this is a problem between GCC and QT, since I applied the change to recompile everything

good day

Hello!
