I'm trying to debug the compiler. I've gotten the gcc/Makefile to compile the programs with '-g3 -O0' so that no function called are rm'ed (the -O0 option) and so that I can see what macros to (the -g3 option). However, I had to trial-and-error edit the Makefile's to change what I thought was the macros for compile options to do it. I made several wrong guesses and had to make a different guess. I finally got it to work; however, then I had a problem with generating the docs because the compile said I didn't have 'makeinfo'. Well, after installing makeinfo, I tried again with the same result. So, I reconfigured with ../src/configure <options>; however, that erased all the changes I made to get '-g3 -O0' into the compile options.
So... I read `man gcc` which claimed passing "CFLAGS=<options>" on the command line is how to do this. Well, since <options> in my case was '-g3 -O0' I had to pass it as CFLAGS='-g3 oO0'. IOW: ../src/configure CFLAGS='-g3 -O0' However, even then, it didn't work for the gcc/Makefile. The top level Makefile did have: TOPLEVEL_CONFIGURE_ARGUMENTS=../src/configure CFLAGS='-g3 -O0' ... CFLAGS_FOR_BUILD = -g3 -O0 However, the gcc/Makefile had: CFLAGS = -g3 so, it looks like passing the CFLAGS to the submake truncated the option after the first word. How do I avoid that? TIA. -Larry
