I did the build the non-persistent way and ran my program with the
debugger. When I got to the breakpoint for the the library function it
says "no line number". See the following from gdb.
3271 pobj=xmlXPathEvalExpression(tag, pctx);
(gdb)
Breakpoint 3, 0x00002ab4493e4480 in xmlXPathEvalExpression ()
from /usr/lib/libxml2.so.2
(gdb)
Single stepping until exit from function xmlXPathEvalExpression,
which has no line number information.
Does this mean the source was removed after the emerge? If so how can I
keep the source.
Also I like the idea of using "/etc/portage/env/category/package" but
I'm not sure what to do since I don't have the env directory. Would I
just do a mkdir -p /etc/portage/env/dev-libs/ and create a file called
libxml2 with CFLAGS="$CFLAGS -g2" in it?
Thanks all,
Dave

How can I modify the CFLAGS before emerging a package? I want to add
-g2 to the compile of libxml2 so I can step through their functions. If
I add -g2 to CFLAGS in make.conf it will do it for all packages which is
not what I want.
Thanks,

Same way as with USE flags, I think.
# CFLAGS="-g2" emerge libxml2
- aegis
