hello,everyone,there is a mistake when using gdb to debug,it said :

" Can't find a source file at "C:/repo/mingw-w64-crt-git/src/mingw-w64/mingw-w64-crt/crt/crt0_c.c" Locate the file or edit the source lookup path to include its location."

and the problem is that the path "C:/repo/mingw-w64-crt-git/src/mingw-w64/mingw-w64-crt/crt/crt0_c.c" is doesnt exsit on my computer,there is no "C:/repo" dir on my computer.how to fix it, thank you in advance!

It's not an error. GDB (Eclipse, really) is trying to display the source for crt0_c.c but can't find it. This only happens when you step into a function in crt0_c.c or when something went wrong within it which would otherwise terminate the program.

Are you stepping into this function (crt0) for a reason? If so, use the assembly view as you've been offered or go find the source for it and tell gdb (via Eclipse) where it is. Use the Source tab in debug configuration dialog

http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.cdt.debug.application.doc%2Ftasks%2Fcdt_t_run_dbg.htm
http://help.eclipse.org/mars/topic/org.eclipse.cdt.debug.application.doc/tasks/cdt_t_run_source.htm?cp=71_4_0_0_6m

If you didn't really mean to be inside the code for crt0_c.c then you can press the up arrow that bends toward the right in the Debug view tool bar and it will take you back to your code (the preceding call, actually). If you don't want these messages then don't step into library routines (with the 90 degree down arrow). Step over them instead (use the curved downward pointing arrow).
