Hi,
--enable-debug, right?Quote:> I'm trying to single step through khtmlpart.

No, they should be in the .so. Try nm --debug-syms libkhtml.so, to see ifQuote:> open ). It seems like the debugging information just isn't present.

1. problem with debugging flag '-g' of gcc
I am having trouble in using the debugging flag -g of the gcc compiler.
Wihout the '-g' in the linking stage I got the final executable without error.
With the '-g' in the linking stage ld complains that it can't find libX11.
/lib/ has libX11.so.3 sym-linked to /usr/X11/lib/libX11.so.3.1.0
/usr/X11/lib/ has libX11.sa and libX11.so.3, but no libX11.a ; is that
the problem ?
I have the Slackware 2.0 distribution
Following provides detail by using the '-v' option:
