TurboFloat FreeBSD / Linux clang linking errorSolved

There is a problem that I dont know yet how to fix. When compiling, it produces:

c++ -g -O2 -Wl,--gc-sections -o tfltchk main.o ../lib/libTurboActivateTurboFloat.a -lpthread../lib/libTurboActivateTurboFloat.a(GlobalVars.o): In function `TF_LIB_NS::GlobalVars::GlobalVars(void (*)(), void (*)())':GlobalVars.cpp:(.text._ZN9TF_LIB_NS10GlobalVarsC2EPFvvES2_+0x15): undefined reference to `TF_LIB_NS::PowerEvents::PowerEvents(void (*)(), void (*)())'GlobalVars.cpp:(.text._ZN9TF_LIB_NS10GlobalVarsC2EPFvvES2_+0x1ce): undefined reference to `TF_LIB_NS::PowerEvents::~PowerEvents()'../lib/libTurboActivateTurboFloat.a(GlobalVars.o): In function `TF_LIB_NS::GlobalVars::~GlobalVars()':GlobalVars.cpp:(.text._ZN9TF_LIB_NS10GlobalVarsD2Ev+0x1bd): undefined reference to `TF_LIB_NS::PowerEvents::~PowerEvents()'GlobalVars.cpp:(.text._ZN9TF_LIB_NS10GlobalVarsD2Ev+0x2a2): undefined reference to `TF_LIB_NS::PowerEvents::~PowerEvents()'c++: error: linker command failed with exit code 1 (use -v to see invocation)*** Error code 1Stop.

This error also occurs when trying to link a dynamic library:

c++ -DHAVE_CONFIG_H -I. -I.. -I../include -g -O2 -MT main.o -MD -MP -MF .deps/main.Tpo -c -o main.o main.ccmv -f .deps/main.Tpo .deps/main.Poc++ -g -O2 -Wl,--gc-sections -Wl,-rpath='../lib' -o tfltchk main.o ../lib/libTurboFloat.so -lpthread../lib/libTurboFloat.so: undefined reference to `TF_LIB_NS::PowerEvents::PowerEvents(void (*)(), void (*)())'../lib/libTurboFloat.so: undefined reference to `TF_LIB_NS::PowerEvents::~PowerEvents()'c++: error: linker command failed with exit code 1 (use -v to see invocation)*** Error code 1Stop.

If compiled with TurboActivate, then there are no errors.

c++ -DHAVE_CONFIG_H -I. -I.. -I../include -Os -s -ffunction-sections -fdata-sections -m64 -g -O2 -MT mainTA.o -MD -MP -MF .deps/mainTA.Tpo -c -o mainTA.o mainTA.ccc++: warning: argument unused during compilation: '-s' [-Wunused-command-line-argument]mv -f .deps/mainTA.Tpo .deps/mainTA.Poc++ -g -O2 -Wl,--gc-sections -Wl,-rpath='../lib' -o tfltchk mainTA.o ../lib/libTurboActivate.so -lpthread

Compilation finished

I need TurboFloat (TurboAktivate does not suit me).

Why there is an error with TF_LIB_NS :: PowerEvents :: PowerEvents and how to get around it?
