Linux "make" @ 100% Error: ../game/libgame.a(Channel.cpp.o):

[intension1992]

Good day,
I have now installed the source, etc. on my home PC (Win10) and works.
On the Linux root he spits me with the command "make" then at 100% following error

Cmake command was "cmake ../ -DCMAKE_INSTALL_PREFIX=/home/wow/server -DWITH_SERVERS=1 -DWITH_SCRIPTS=1 -DWITH_TOOLS=0 -DWITH_USE_SCRIPTPCH=1 -DWITH_USE_COREPCH=1 -DWITH_WITH_WARNINGS=0 -DWITH_WITH_COREDEBUG=0"

This is the Error:

../game/libgame.a(Channel.cpp.o): In function `Channel::Say(unsigned long, char const*, unsigned int)':
Channel.cpp.text+0x62ec): undefined reference to `Player::BuildPlayerChat(WorldPacket*, unsigned char, std::strin g const&, unsigned int, char const*, std::string const&) const'
collect2: error: ld returned 1 exit status

make[1]: *** [src/server/worldserver/CMakeFiles/worldserver.dir/all] Error 2
Makefile:117: recipe for target 'all' failed
make: *** [all] Error 2

I'm still not to know at the moment in a position what it is exactly because to fix let it .
If someone solves the problem + explanation I would be willing even a little pocket money by example To charged 5 €
