Hi... I'm back to work on mod_atom and chasing a weird bug around.
Anyhow I totally can't figure out what some apr code is doing so I
wanted to step into it with the debugger. This sounds lame, but I
can't figure out how to build an httpd that has APR linked with
debug information.
What are the approved incantations to make an httpd with some
control over the -O and -g options?
It helps if you remember apr's CFLAGS are trusted by apr-util, httpd
etc, but you need to re - ./configure after rebuilding apr to utilize
this trick.
So... something like this?
> rm -rf /usr/local/apr/*
> cd srclib/apr
> "CFLAGS=-g" ./configure
> make
> make install
> cd ../..
> "CFLAGS=-g" ./configure
> make
> make install
I *think* I did that. If you tell me you think something like that
should work, I'll try again.
At the moment, the symptom is:
