Public bug reported:
Binary package hint: lmbench
Lmbench uses a script called "os", that then calls "gnu-os" to find the
configuration name of the system while building and running lmbench.
When building, the result is used to deploy the bin files in a directory
with the same system configuration name. While running lmbench it then
uses the same script to find the correct location of the bin files.
Problem is that for Lucid, Maverick and Natty the target ARM system is
an armv7 compatible board, and the package was built during Karmic time,
using an armv5 machine as builder. The same package was copied to later
distro revisions without rebuilding it.
Example, in Maverick:
Lmbench bin directory: /usr/lib/lmbench/bin/armv5tel-linux-gnu
OS script output: armv7l-linux-gnu
Then when you run lmbench-run it will give many error messages, saying it can
find the scripts used during configuration:
# lmbench-run
...
Hang on, we are calculating your timing granularity.
./config-run: 138: /usr/lib/lmbench/bin/armv7l-linux-gnu/msleep: not found
./config-run: 139: /usr/lib/lmbench/bin/armv7l-linux-gnu/enough: not found
OK, it looks like you can time stuff down to usec resolution.
Hang on, we are calculating your timing overhead.
./config-run: 144: /usr/lib/lmbench/bin/armv7l-linux-gnu/msleep: not found
./config-run: 145: /usr/lib/lmbench/bin/armv7l-linux-gnu/timing_o: not found
OK, it looks like your gettimeofday() costs usecs.
Hang on, we are calculating your loop overhead.
./config-run: 150: /usr/lib/lmbench/bin/armv7l-linux-gnu/msleep: not found
./config-run: 151: /usr/lib/lmbench/bin/armv7l-linux-gnu/loop_o: not found
OK, it looks like your benchmark loop costs usecs.
...
Just rebuilding the package makes it work fine.
