Hi,
I am having problems cross compiling LTTNG for the ARM platform. Everything
compiles fine, except the TOOLS.
The error I am getting is:
libtool: warning: library
'/home/USER/work/LTTNG/sysroot/usr/local/lib/liburcu.la' was moved.
/bin/grep: /usr/local/lib/liburcu-common.la: No such file or directory
/bin/sed: can't read /usr/local/lib/liburcu-common.la: No such file or
directory
libtool: error: '/usr/local/lib/liburcu-common.la' is not a valid libtool
archive

It is looking for "/usr/local/lib/libiconv.la" when it should be looking for
"/home/USER/work/LTTNG/sysroot /usr/local/lib/libiconv.la" which is where
the builds are being installed.
In desperation I tried setting -with-sysroot in the configuration step to
the appropriate directory but it made no difference.
My build scripts seem okay but maybe I am missing something obvious. I also
tried a couple of other build scripts that were on the web as examples of
cross compiling LTTNG with similar results, so I wonder if the build
environment I am using is a little "different", but I have no control over
that.
This is the script that I am using. It is based on one that was posted as a
successful example of cross compiling LTTNG, and I have made some changes
for my environment. Works well for everything except the tools.
All suggestions on where the problem lies are welcome.
