Hi I'm trying to build a very simple project composed of one source file and a linker script : file f1.c : #include <stdio.h> extern void fct1_wrongname(); void fct9() { printf("I'm fct9\n"); } int main( int argc, char** argv) { fct1_wrongname(); return 0; } end of file f1.c This file is compiled with command : gcc -O0 -xc -g -Wall -c f1.c -of1.o then build with : ld -T'Link.cmd' -O0 -Map out.map -o rename.exe f1.o file Link.cmd contains : fct1_wrongname = fct9 ; end of file Link.cmd Function fct1_wrongname doesn't exist, and I want to replace the call of this function by a call of fct9. I always get this error message : Link.cmd:4: undefined symbol `fct9' referenced in expression I need to use a linker script (here Link.cmd) to apply this to a larger project, and I can't use symbol definition (i.e. -D"fct1_wrongname=fct9") because there are to many symbols. I've been looking for a solution for a long time, but I couldn't find anything. Can anybody help me ?
