possible that the new kernel was compiled with a different compiler

- The programs you want to profile should have debugging symbols, or

you won't get much usable information. On a Fedora Core system,

installing the relevant -debuginfo package should be sufficient.

On Ubuntu and Debian, the debug packages are called <package>-dbg.

The X server as shipped by most distributions uses its own home-rolled
55

module loading system and Sysprof has no way to deal with that, so if you
56
run sysprof with your normal X serverr you won't get any information about
55
run sysprof with your normal X server you won't get any information about
57
56
how time is spent inside the X server.
59
To fix this you have to compile your own X server:
58
On Ubuntu and Debian there is a package, xserver-xorg-dbg, containing a
59
binary called Xorg-debug that is built in such a way that sysprof can use
60
it. On other systems, to get an X server with usable symbols you
61
have to compile your own:
61
63
(1) Compile the X server to use ".so" modules:
64
66
xc/config/cf/xorgsite.def.
66
68
If you are compiling the CVS version of the X server
67
(the one that will eventually become 7.0), then this is
69
(the one that will eventually become 6.9), then this is
68
70
already the default.
74
- Don't run "make install" yet. (See below).
72
(2) Install the X server making sure it can't see any ".a" files. If
73
you install on top of an existing installation, just do
76
(2) Make sure the new X server can't see any old ".a" files lying
77
around. If you install on top of an existing installation, just do
75
79
find /usr/X11R6/lib/"*.a" | sudo xargs rm
77
and install the newly compiled X server.
81
then run "make install" as root to install the newly compiled
79
84
If a ".so" X server finds .a files in its module path it will
80
85
try to load those in preference to .so files and this causes
87
92
you why, but then I'd have to kill you.
