Hi dear experts, In order to use the gprof in the SDE 5.02 toolchain, I compiled a program with '-p' option but the compiler responsed with a error. I have checked the startup assembly code crt0.sx. There is an address operation which need the address of '_ecode'. Which library has the symbol '_ecode'? Could you give me a clue? Thanks in advance! Best regards, Yidan PS. The following is the error messge: sde-gcc -O -g -mcpu=4kc -mips32 -EB -mno-float -DGNUSIM -D__SIM '-Afloat(no)' -I../../kit/GSIM32B/../gnusim -c -DMCRT0 ../../kit/share/crt0.sx -o mcrt0 .o sde-gcc -g -p -mcpu=4kc -mips32 -EB -mno-float -DGNUSIM -D__SIM '-Afloat(no)' -I../../kit/GSIM32B/../gnusim -c hello.c -o hello.o sde-make[1]: Entering directory `/cygdrive/c/sde/sde/kit/GSIM32B' sde-make[1]: Nothing to be done for `kit'. sde-make[1]: Leaving directory `/cygdrive/c/sde/sde/kit/GSIM32B' sde-gcc -mcpu=4kc -mips32 -EB -mno-float -Ttext 80000400 -L../../kit/GSIM32B ../../kit/GSIM32B/ramstart.o mcrt0.o hello.o -lc -lram -lgcc -lc -le -lram -l c -lgcc ../../kit/GSIM32B/crtn.o -o ex1ram mcrt0.o: In function `__fini': /cygdrive/c/sde/sde/examples/helloworld/../../kit/share/crt0.sx(.text+0x60): und efined reference to `_ecode' /cygdrive/c/sde/sde/examples/helloworld/../../kit/share/crt0.sx(.text+0x64): und efined reference to `_ecode' collect2: ld returned 1 exit status sde-make: *** [ex1ram] Error 1
