Having done a from-clean build, and been unable to debug because my
autogen.lastrun contains --enable-symbols - and that now fails to do
anything - I did some digging to try to restore that functionality.
It appears that prepending:
CFLAGS=-Os -g
CXXFLAGS=-Os -g
to your autogen.lastrun will restore the original --enable-symbols
functionality; and of course leaving that option there does no harm if
you want to share your autogen.lastrun with older versions.
Why do I extensively use that option, though I'm not a packager:
* I like to run the code the end-user runs - warts and all.
* I like to be able to profile accurately without re-building
everything (cf. above)
* Having no symbols / debug-info is rather unhelpful for both
debugging, and profiling though perhaps it's a reasonable
default for size reasons
Anyhow - no doubt it's a big improvement to get the CFLAGS etc. pushed
through configure and used everywhere cleanly :-)
HTH,
Michael.
