[coldfire-gnu-discuss] GNU link error with code sourcery

[vika vika]

Hi All
  I could compile and link my source code with codesourcery GNU but now I am facing problem with C++ constructor. my program crash at c++ constructor. I am giving my linker file. C program works fine. 
  I am linking my code as follows 
  CF2_CC :=m68k-elf-gcc -fno-builtin -mcpu=5275 -mdiv -gstabs 
  CF2_CCP :=m68k-elf-g++ -fno-builtin -mcpu=5275 -mdiv -gstabs 
   
  //c++ code 
  $(OBJS_CC): %.o: ./xyz/xyx/%.cpp
  $(CF2_CCP) -c  -Wa,-adhls=$*.ls -o $@ $< 
   
  //similarly c code 
   
   
  //linking all with g++
   
  gnutest.obj: $(C_CPP_OBJ) linkfile.ld 
  $(CF2_CCP) $(LDFLAGS) -Tlinkfile.ld -lgcc -nostartfiles -o $@ $(C_CPP_OBJ) 
   
   
  My linker file
