 Posted: Mon Jun 24, 2002 11:24 am Post subject: Setting up a debugging system? |
 |
|
I'm a competent programmer and when I come across a bug in the system, I'd like to fix it. So I'd like to have all the source code for my system installed locally and have all programs compiled with debug symbols. Trying to do this with a "conventional" distro is tricky; gentoo seems like the answer. But I can't quite get there....
1) I've added the -g option to CFLAGS so that compilation should include debug info, but how do I stop installed files being stripped of the debug information?
2) How do I get portage to keep the source code tree after compilation?
3) When/If I do find a bug and fix it in my local source tree, what is the correct procedure to follow with portage to build the changed version?
4) How would I then stop portage clobbering my changed code in the local source tree?
Any help would be much appreciated.
Thanks

1. see /usr/portage/eclass/debug.eclass
so you can probably put
| Code: |
DEBUG="yes"
RESTRICT="nostrip"
|
in your /etc/make.conf and make sure not to define -fomit-frame-pointer in your C(xx)FLAGS. -g -O2 -march=yourproc is probably best bet for debugging
2. see FEATURES in /etc/make.conf (at bottom)
3. use ebuild instead of emerge, see documetation
4. 2 should take care of it, but portage has been a bit flakey lately and I don't know which version would play best
if you get all this worked out, let me know! I want to set up a pure debug system on another partion sometime soon. It would be nice if you could specify that static libs be debugging and dynamic not (longer compile maybe, but hey) and then when developing, link statically and for everyday apps, full speed ahead. ccache may help greatly to reduce recompiling static libs too. |
