expected unqualified-id before string constant

I got an error on the cypwin compile client

g++ -DHAVE_CONFIG_H -I. -I/usr/local/lib/wx/include/msw-unicode-3.0 -I/usr/local/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXMSW__ -DNDEBUG -DLINUX -I/usr/local/lib/wx/include/msw-unicode-3.0 -I/usr/local/include/wx-3.0 -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXMSW__ -DDATADIR=’"/usr/local/share"’ -DVARDIR=’"/usr/local/var"’ -DSBINDIR=’"/usr/local/sbin"’ -DBINDIR=’"/usr/local/bin"’ -g -O2 -MT client/gui/urbackupclientgui-GUI.o -MD -MP -MF client/gui/.deps/urbackupclientgui-GUI.Tpo -c -o client/gui/urbackupclientgui-GUI.o test -f 'client/gui/GUI.cpp' || echo './'client/gui/GUI.cpp
