hi.
         If I set the global  compiler flags with -gdwarf when configure the  ecos,then I get this error when compile the application:
        /cygdrive/d/ecossave/s3c44b0ram_install/lib/libminigui.a(timer.o)(.debug+0x1723): undefined reference to `.L_E453'

But if I configure ECOS with -g ,there isn't this problem? why?
